1 IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS

This manual contains important instructions that should be followed during installation of your Liebert®

EXLS1™ UPS. Read this manual thoroughly, paying special attention to the sections that apply to your

installation, before working with the UPS. Retain this manual for use by installing personnel.

WARNING! Risk of electrical shock. Can cause personal injury or death. This UPS has several

circuits that are energized with high DC as well as AC voltages. Check for voltage with both AC

and DC voltmeters before working within the UPS. Check for voltage with both AC and DC

voltmeters before making contact. Only properly-trained and qualified personnel wearing

appropriate safety headgear, gloves, shoes and glasses should be involved in installing the UPS

or preparing the UPS for installation. When performing maintenance on any part of the

equipment under power, service personnel and test equipment should be standing on rubber

mats. In case of fire involving electrical equipment, use only carbon dioxide fire extinguishers or

those approved for use in fighting electrical fires.

WARNING! Extreme caution is required when performing installation and maintenance. Special

safety precautions are required for procedures involving handling, installation and maintenance

of the UPS system. Observe all safety precautions in this manual before handling or installing

the UPS system. Observe all precautions in the Operation and Maintenance Manual, SL-26090,

before as well as during performance of all maintenance procedures. Observe all DC safety

precautions before working on or near the DC system.

WARNING! Risk of heavy unit falling over. Improper handling can cause equipment damage,

injury or death. Exercise extreme care when handling UPS cabinets to avoid equipment damage

or injury to personnel. Locate the center of gravity symbols and determine the unit’s weight

before handling each cabinet. Test lift and balance the cabinets before transporting them.

Maintain minimum tilt from vertical at all times. Slots at the base of the module cabinets are

intended for forklift use. Base slots will support the unit only if the forks are completely

beneath the unit. Read all of the following instructions before attempting to move, lift or

remove packaging from the unit, or to prepare the unit for installation. The UPS module weighs

up to 4667 lb. (2117 kg).

WARNING! Risk of electrical shock and fire. Can cause equipment damage, personal injury or

death. Only normal safety precautions are necessary under typical operation and with all UPS

doors closed. The area around the UPS system should be kept free of puddles of water, excess

moisture and debris. Only test equipment that is designed for troubleshooting should be used.

This is particularly true for oscilloscopes. Always check with an AC and DC voltmeter to ensure

safety before making contact with the UPS or using tools to work on any UPS component.

Dangerously high potential electric charges may exist at the capacitor banks and at the DC

connections even when input power is turned Off. All wiring must be installed by a properly

trained and qualified electrician. All power and control wiring must comply with all applicable

national, state and local codes. One person should never work alone, even if all power is

disconnected from the equipment. A second person should be standing-by to assist and to

summon help in case of an accident.

NOTICE

This unit complies with the limits for a Class A digital device, pursuant to Part 15 Subpart J of

FCC rules. These limits provide reasonable protection against harmful interference in a

commercial environment. This unit generates uses and radiates radio frequency energy and, if

not installed and used in accordance with this instruction manual, may cause harmful

interference to radio communications. Operation of this unit in a residential area may cause

harmful interference that the user must correct at his own expense.

2 MECHANICAL INSTALLATION

2.1 Pre-installation Planning

This section describes the requirements that must be taken into account when planning the positioning

and cabling of the UPS and related equipment.

Installing personnel should observer these general procedures and practices. The particular conditions of

each site will determine the applicability of such procedures.

WARNING! Risk of electrical shock. Can cause injury or death. Special care must be taken when

working with the batteries associated with this equipment. When the batteries are connected

together, the battery-terminal voltage will exceed 400VDC and is potentially lethal.

NOTE: All equipment not referred to in this manual is shipped with details of its own mechanical and

electrical installation.

NOTICE

Risk of incorrect input power connection. Can cause equipment damage.

The standard Liebert® EXL S1™ Installer Guide UPS is suitable for connection to 60-Hz,

3-phase, 3-wire-plus-ground input power.

NOTE: Do not apply electrical power to the UPS equipment before the arrival of the commissioning

engineer. Connecting power before the commissioning engineer determines the system is properly

installed may void the warranty.

2.2 Preliminary Checks

Before installing the UPS, carry out the following preliminary checks:

•Visually examine the UPS equipment for transit damage, both internally and externally. Report

any damage to the shipper and to your Vertiv representative immediately.

•Verify that the correct equipment is being installed. The equipment supplied has an

identification tag on the interior doors stating the type, size, and main-calibration parameters

of the UPS.

•Verify that the UPS room satisfies the environmental conditions stipulated in the equipment

specification, paying particular attention to the ambient temperature and air-exchange

system.

2.3 Environmental Considerations

2.3.1 UPS Room

The UPS module is intended for indoor installation and should be located in a cool, dry, clean-air

environment with adequate ventilation to keep the ambient temperature within the specified operating

range (see Table 5.3 on page42).

The UPS is cooled with the aid of internal fans. Do not cover the ventilation openings. Cooling air must

enter and exit the cabinets freely to prevent overheating or malfunctioning.

2 Mechanical Installation 3

The UPS is equipped with air filters behind the front doors. A schedule for inspection of the air filters is

required. The period between inspections will depend upon environmental conditions.

When using bottom-entry, the conduit plate must be installed.

NOTE: The UPS must be installed on concrete or other non-combustible surface.

NOTICE

There is a potential risk to the operational integrity of an installed UPS system by the presence

of foreign material inside or in the vicinity of the UPS module.

This risk is especially high if conductive materials find their way inside the UPS module.

The risk potentially involves damage to the installed UPS equipment and subsequent

degradation or loss of power to the connected critical site load.

Vertiv applies the highest safety standards in equipment design to ensure that no live parts

are exposed to external contact, and also to ensure that the equipment is protected against

the introduction of foreign bodies during operation. However, it is not possible for Vertiv. to

ensure that foreign bodies will not be introduced during on-site installation, or when the UPS

doors and covers are open and the electrical terminals are exposed to allow power line

connections to be made by the electrical contractor/installer.

To prevent major disruption to site operations and risk to property and personnel, including

the possibility of a fatality, each site’s facility manager or construction manager must prevent

foreign bodies from being introduced into the UPS module.

All UPS modules are thoroughly inspected by Vertiv engineers before being placed into service

and testing on-site. However, the person responsible for the site must ensure that the UPS

module and the immediate surroundings are kept clean and free from any possible conductive

material such as metal foil, food wrappers, cable shields, washers and other hardware, scrap

metal and dust.

If the UPS system is shut-down after placement into service and testing are completed, the

UPS room must be kept clean to avoid the possibility (during restart) of the considerable

volume of air-flow produced by UPS operation to dislodge and/or drag any foreign bodies into

the equipment, which would result in system failure and possible supply interruption to the

critical site load, and several hours of downtime resulting from the damage typically associated

with such events.

If the UPS is left running/operational after placement into service and testing, the room must

be kept clean to prevent foreign bodies from entering the UPS module via its forced air-flow.

Vertiv | EXL S1™ Installer Guide

2.3.2 Storing the UPS and Batteries for Delayed Installation

If the UPS system will not be installed immediately, store it indoors in a clean, dry, and cool location (see

Table 5.3 on page42). If the system includes a battery cabinet, the batteries’ requirements dictate the

storage conditions. Unpacked, install, and charge batteries as soon as possible after delivery.

NOTICE

Risk of failure to properly charge batteries. Can cause permanent damage to batteries and void

the warranty.

Batteries will discharge during storage. Batteries must be recharged as recommended by the

battery manufacturer. A notice of “Charge Before Date” is affixed to each cabinet that has

batteries inside. The “Charge Before Date” is calculated based on storing the batteries at 77°F

(25°C). Storage at a higher temperature will increase the rate of self-discharge, which requires

earlier recharge. Consult the battery manufacturer on how to determine when the batteries

need to be recharged.

2.3.3 Installation Altitude

The maximum operating altitude of the UPS, without derating, is 3300ft(1000m).

2.4 Positioning

The cabinet is structurally designed to permit lifting from the base with a forklift, pallet jack, or similar

equipment.

Access to the power terminals, auxiliary terminal blocks and power switches is from the front and top.

The doors and top low-voltage cover can be opened for access to the power connection bars, auxiliary

terminal blocks and power isolators. The front door can be opened 90 degrees for more flexibility in

installations.

2.4.1 Moving the Cabinets

Plan the travel route between the point of arrival and the unit’s position to make sure that all passages are

wide enough for the unit and that floors are capable of supporting its weight. For instance, check that

doorways, lifts, ramps, and so on, are adequate and that there are no impassable corners or changes in the

level of corridors that would prevent passage.

Ensure that the UPS weight is within the designated surface weight loading (kg/cm2) of any handling

equipment. For weight details, see Table 5.2 on page41.

Move the UPS with a forklift or similar equipment to ease the relocation and to reduce unit vibration. The

bottom structure of the UPS will support the unit only if the forks are completely beneath the unit. The

optional battery cabinets also should be moved with a forklift or similar equipment.

Ensure that any equipment used in moving the UPS cabinet has sufficient lifting capacity to transport

the unit. Care must be taken to protect the panels. Do not tilt the UPS or other system cabinet more than

15degrees.

Handling with straps is not authorized.

2 Mechanical Installation 5

WARNING! Risk of heavy unit falling over. Improper handling can cause equipment damage,

injury or death. Because the weight distribution in the cabinet is uneven, use extreme care while

handling and transporting. Take extreme care when handling UPS cabinets to avoid equipment

damage or injury to personnel. Locate center of gravity symbols and determine unit weight

before handling each cabinet. Test lift and balance the cabinets before transporting. Maintain

minimum tilt from vertical at all times. The UPS module weighs up to 4667 lb. (2117 kg).

2.4.2 Clearances

The UPS has no ventilation grilles at either side or at the rear. Leave a distance of 24in. (610mm) between

the top of the UPS and any overhead obstacles for service and adequate circulation of air from the unit.

Clearance around the front of the equipment should be sufficient to enable free passage of personnel

with the doors fully opened, about 50in. (127cm). In the rare instance of module replacement, 50in.

(127cm) of clearance is required for the Service team to perform module replacement. 50in. (127cm)

allows adequate clearance for both the module and the heavy-duty lift used by Service team to remove

and replace the modules. If 50in. (127cm) is not available, then the Service team will instead replace

components and subassemblies in the modules as part of their repair process.

2.4.3 Raised-Floor Installations

If the equipment will be installed on a raised floor, mount the UPS on a pedestal suitably designed to

accept the equipment-point loading. Refer to the base view to design this pedestal.

2.4.4 Floor Anchors—Optional

For seismic-resistant installations, special floor anchors must be used for the UPS and matching battery

cabinets; see 5on page39.

2.4.5 Kick Plate Installation—Standard

Kick plates must be installed. If the unit will be installed in a position that does not permit access to rear of

the UPS, install the kick plates before the unit is placed in its final position.

2.4.6 Special Considerations for 1+N Parallel Systems

Consider the grounding configuration of your system before finalizing module placement See Configuring

Ground Connections on page 29.

The cabling impedance must be closely matched to ensure proper load-sharing. Mismatched impedance

may cause an overload on one module in a 1+N system, triggering a shutdown and loss of power to the

connected load. Mismatched cable impedance is amplified when a 1+N system is operating on bypass

because the power on the bypass path is not controlled. We recommend matching the impedance in the

bypass path of paralleled systems as closely as possible to ensure good bypass current sharing.

The 1+N UPS Bypass Current Sharing Inductor option can be used to minimize the effects of cable

impedance mismatch.

The impedance mismatch can also be minimized by controlling the wiring length of each unit. The design

and the layout of the UPS system and associated panels and cabling should be examined closely to

ensure that cable lengths and impedance are closely matched.
