1. INTRODUCTION

1.1 SYSTEM DESCRIPTION

The MINUTEMAN CP Series UPS is an advanced true on-line sinewave uninterruptible power system

with bypass switch. It provides reliable, regulated, transient-free AC power to your sensitive

equipment, ranging from computers and telecommunication systems to computerized instruments.

Because the UPS is an on-line design, conditioned power is provided continuously to the attached

devices. Unlike the standby UPS, its on-line structure is constantly regulating, filtering the output

power when commercial power is present. During electrical power failure, the unit employs its

internal maintenance-free battery to supply back-up power without any transfer time.

In the event of overload or inverter failure, the UPS will transfer to the bypass as an alternate source.

The UPS can transfer back to the inverter automatically after the overload condition has been

cleared. All the above transfer time is within four (4) milliseconds that can ensure your equipment

operating uninterruptedly.

INSTRUCTIONS

1.3 SAFETY

This manual contains important instructions for MINUTEMAN CP series that should be followed

during installation and maintenance of the UPS and Batteries.

CAUTION:



The UPS contains voltages, which are potentially hazardous. Qualified service personnel

should perform all repairs.



The UPS has its own internal energy source (battery). The output receptacles maybe live

even when the UPS is not connected to an AC supply.



Symbol meaning:

Alternating current supply

Symbol for equipment grounding conductor.

On and standby symbol for 220V, 230V, 240V version.

On and Off symbol for 110V, 120V version.



Internal Battery supply voltage _______

UPS MODEL CP500: 24V _ _ _

UPS MODEL CP1K: 60V _ _ _



An insulated grounding conductor —— The wire shall be 18 AWG minimum PVC UL

1015 green or green with yellow strip.



The grounding conductor described in above item is to be grounded to earth at the

service equipment.



Plug the UPS into a grounded 3-wire AC receptacle.



Replacement of batteries should performed or supervised by personnel knowledgeable of

batteries and the required precautions. Keep unauthorized personnel away from battery.



When replacing batteries, use the same number and the following type batteries:

Matsushita (or Panasonic) Electric Works. Type LCR12V6.5P, rated 12V.



Do not dispose of battery or batteries in a fire, the battery may explode.



Do not open or mutilate the battery or batteries, released electrolyte is harmful to the skin

and eyes. It may be toxic.



A battery can present a risk of electrical shock and high short circuit current. The

following precautions should be observed when working on batteries.



Remove watches, rings or other metal objects.



Use tools with insulated handles.

For safe and continuous operation of the UPS depend partially on the care taken by user. Please

observe the following precautions:



Do not disassemble the UPS.



Do not attempt to power the UPS from any receptacle except a 2-pole 3-wire grounding

receptacle.



Do not place the UPS near water or in environment of excessive humidity.



Do not allow liquid or any foreign object to get inside the UPS.



Do not block air vents in front of the UPS or air exhausts in the back.



Do not plug appliances, such as hair dryers, into the UPS receptacles.



Do not place the UPS under direct sunshine or close to heat-emitting source.



A certified detachable power supply cord is to be used with this equipment. For a related

current up to 10A, a type not lighter than HO5VV-F3G 0.75mm2shall be used. For

CP3K/2, rated current 16A, a type not lighter than HO5VV-F3G 1.5 mm2 shall be used.



Caution - Electric shock hazard. Battery circuit is not isolated from the input voltage.

There may be hazardous voltage between battery terminals and ground. Check that

there is no voltage before touching!



Caution -- Electric shock hazard. Even after disconnection from the mains input

voltage, components inside the UPS are still connected to the battery and are at

hazardous potential. Disconnect the battery supply circuit before carrying out servicing or

maintenance work.

1.4 DISPLAYS AND SWITCH

MAIN switch: Turn on the UPS by depressing the front panel switch into the position " | " and

turn off the UPS by depressing switch to the position " ".

LINE LED: This light means that the incoming AC line is normal.

BYPASS LED: The light means that the UPS is providing power directly from the incoming

AC line through the bypass line.

FAULT LED: The light is on when the UPS is in fault condition. In the meantime, the alarm

beeps continuously.

LOAD LEVEL LED: The light is a bar graph and indicates how much load is on the UPS.

The lights are in 25% increments. If the UPS is overloaded, the LED's show over 100%, then

you have connected too many devices into the UPS. Unplug the least critical equipment,

such as a printer etc.

1.5 COMMUNICATION PORT

The communication port on the back of the UPS may be connected to a computer. This port allows

the computer to monitor the status of the UPS and control the operation of the UPS in some cases.

Its major functions normally include some or all of the following:

A. COMUNICATION PORT INTRODUCTION



To broadcast a warning when power fails.



To close the files before the battery reserve is exhausted.



To turn off the UPS and the computers.

Some computers are equipped with a special connector to link with this communication port.

Some computers require a special plug-in card. Some computers may need a special UPS

monitoring software. Contact your dealer for the detail of different interface kits.

Pin 2: The relay will close when

input power fails.

Pin 3: The relay will become open

when input power fails.

Pin 4: Common for pins 2, 3, and 5.

Pin 5: The relay will close when the

battery inside the UPS has

less than about 3 minutes

(CP500: 1.5 minutes) of

backup time left.

Pin 6: User may send a high level

signal (+5V ~ + 12V) for

over 500 ms to turn off the

UPS. But it can only

activate when input power

fails.

PIN 7: Common for pin 6.

NOTE:

1. Relay rating +24V 0.5A

2. Pin 7 should be connected to ground only.

B. RS232 COMMUNICATION PORT INTRODUCTION (FOR CP3K/2 ONLY)



INTRODUCTION:

The RS232 communication port provides the following features:

1. Monitor charger status.

2. Monitor battery status and condition.

3. Monitor inverter status.

4. Monitor UPS status.

5. Monitor the utility status.

6. Provide the power switch function for computer to turn on and off the utility to the

computer on schedule for power saving.

Computer will control information exchange by a query followed by <cr>. The UPS will

respond with information followed by a <cr> or action.
