1 Safety Description

This chapter introduces the safety announcements. Prior to performing any work on the UPS, please read the

user manual carefully to avoid human injury and device damage by irregular operations.

1.1 Safety Announcements

This section introduces the safety announcements that must be complied with and pay special attention while

installing, using, maintenance and other relative operations.

CAUTION!

Before operating, please read the announcements and operation instructions in this

section carefully to avoid accident.

The DANGER, WARNING, CAUTION, etc. in the manual are not all the safety announcements

that you must abide by, they are just the supplements for the safety announcements

during operating.

NOTE!

Our company does not undertake the responsibility caused by violating common safety

operation requirements or the safety standard of design, manufacture, and use.

1.1.1 Safety Instructions

CAUTION!

There exists high temperature and high voltage inside the UPS. During usage, strictly

comply with all warnings and operation instructions on the UPS and in the user manual.

CAUTION!

The UPS is class C3 device. If it is used in residential purpose, it may cause wireless

interference. User should take actions to avoid the interference.

• No liquid or other objects should be allowed to enter the UPS.

• UPS must be well grounded.

• In case of ﬁre, please use dry powder ﬁre extinguisher. If liquid ﬁre extinguisher is used, it may cause

electric shock.

1.1.2 User Instructions for Battery

CAUTION!

Please use speciﬁed battery. Non-speciﬁed battery will damage the UPS.

• Only authorized professional can replace battery. Do not wear conductive objects, such as watches,

bracelets, and rings while handling. Wear rubber shoes and gloves and use tools with insulated

handle.

• Don't put tools or other conductive objects on the battery.

• Shorting the positive and negative poles of the battery or connecting them in reverse is prohibited.

This is done to prevent the risk of ﬁre or electric shock.

PREMIUS 7.5 KVA - 20 KVA UPS USER MANUAL

• Before connecting or disconnecting the battery terminals, disconnect the charger ﬁrst.

• The battery must be of the same type, model and manufacturer.

• Battery should be kept away from ﬁre source or other electrical equipment that may easily cause

spark to avoid human injury.

• Don't open or destroy the battery. The electrolyte in the battery includes strong acid, which will be

harmful to skin and eyes. If you come in contact with the acid, clean it by running water immediately

and visit the hospital.

• The waste battery should be disposed according to the local regulations.

1.1.3 Anti-Static Protection

CAUTION!

The static electricity generated by human bodies may damage the electrostatic-

sensitive components on PCB. Before touching the sensitive component, please wear

anti-static device and connect the other end of the anti-static device to the ground.

1.2 Operation and Maintenance Requirements

CAUTION!

Only authorized professionals are allowed to open the UPS chassis, or it may cause

electric shock and failure of the UPS. This will make it out of warranty.

• If the UPS needs to be moved, rewired, or maintained, disconnect all electrical connections, including

AC power, battery power, etc., to isolate the power input. Do not work on the UPS until it has been

completely powered off (wait for at least 10 minutes). Otherwise, there may still be electricity present

in the output, which could lead to an electric shock.

• When dismantling the fan, avoid placing your ﬁngers or tools into the rotating fan to prevent damage

to the device or injury to yourself.

1.3 Environment Requirements

DANGER

Do not place the UPS in an environment where there is inﬂammable, explosive gas,

or smog. Avoid conducting any operations in such an environment.

• Avoid using the UPS in places with direct sunlight, rain, or moisture.

• The normal operating temperature range for the UPS is 0ºC to 40ºC, with a relative humidity of 0%

to 95%, and without condensation (the recommended operating temperature is 20ºC to 25ºC with a

humidity of about 50%).

• Place the UPS on a ﬂat, vibration-free surface with a vertical gradient of less than 5°. Ensure there

is good ventilation around the UPS. Maintain a clearance of at least 300mm to 500mm between the

rear or sides of the UPS and adjacent devices or walls. Insufﬁcient ventilation can lead to increased

temperatures inside the UPS, potentially reducing the lifespan of internal components and affecting

the overall UPS lifespan.

• The UPS must be operated at altitudes below 2000m. If the altitude exceeds 2000m, it is necessary to

reduce the rated power in accordance with IEC62040-3:2011 before usage.

NOTE!

• The wiring terminals for the 31 mode exhibit slight differences. For speciﬁc

information regarding the wiring terminals for each mode, please refer to Section

3.4.1 Wiring Operations.

• The intelligent slot is an optional feature and includes the following components:

a built-in SNMP card, an RS485 + dry contact card, and a communication protocol

transfer card.

• If the BMD (Bypass Maintenance Device) and EPO (Emergency Power Off) detection

functions are not required, kindly short the ports using the provided 4P terminal.

When these functions need to be activated, remove the short wire from the BMD or

EPO port and connect it to the corresponding status signal input on the maintenance

bypass breaker or EPO system.

CAUTION!

• The UPS can operate normally only when both the bypass maintenance switch state

detection (BMD) and the EPO port are separately shorted.

• If the BMD port is disconnected, the UPS will switch to bypass power supply mode,

and simultaneously, the LCD will display a BMD fault notiﬁcation. Upon reconnecting

the port with a short connection, the fault will automatically clear.

• In the case of the EPO port being disconnected, the UPS will initiate a shutdown

of both the inverter and bypass output. Simultaneously, the LCD will indicate an

EPO fault. To rectify this, the UPS must be completely powered down, and the EPO

port should be short-circuited. Following this action, the fault will be automatically

cleared.
