About Your New PowerStack UPS

This Uninterruptible Power Supply (UPS) is designed to prevent
blackouts, brownouts, sags and surges from reaching your computer
and other valuable electronic equipment. This UPS also filters out
small utility line fluctuations and isolates your equipment from large
disturbances by internally disconnecting from the utility line, while
supplying power from its internal batteries until the utility line
returns to safe levels.

While running on battery, an internal alarm will sound (periodic
beeps).

If the utility power does not return, the UPS will continue supplying
power to the connected equipment until exhausted. A continuous
beeping will sound two minutes before the UPS’s final low battery
shutdown. If using a computer, you must manually save your files
and power down before the UPS turns itself off.

Installation and Setup

1. Install UPS

• Plug the power cord into the power supply.

2. Connect Equipment

• Do not power laser printers through the UPS.

• Use your equipment’s power cords to connect to

the UPS.

• Turn on all connected equipment.

3. Turn on UPS

• Press the UPS’s ON switch to turn on your UPS.

This will power-up connected equipment.

I

• The unit performs a self-test automatically when

turned on, and every two weeks thereafter.

• The UPS charges its battery whenever it is

connected to utility power. The battery charges
fully during the first 4 hours of normal operation.
Do not expect full runtime during this initial charge
period.

Troubleshooting

Use the chart below to solve minor UPS installation problems.
Contact APC for assistance with complex UPS problems. See the
User’s Manual for a location near you.

Problem and

Possible Cause

UPS will not turn on.

• ON button not pushed. Press the ON button once to power the

UPS and the load.

• UPS not connected to AC

power supply.

• UPS input circuit breaker

tripped.

• Very low or no utility

voltage.

• Battery not connected

properly.

Check that the power cable from the
UPS to the power supply is securely
connected to the AC power source.
Reduce the load on the UPS by
unplugging equipment and reset the
circuit breaker (on back of UPS) by
pressing the plunger back in.
Check the AC power supply to the UPS
with a table lamp. If very dim, have
the utility voltage checked.
Confirm the battery connections.

UPS will not turn off.

• Internal UPS fault. Do not attempt to use the UPS. Unplug

the UPS and have it serviced
immediately.

UPS operates on-battery although normal line voltage exists.

• UPS’s input circuit breaker

tripped.

• Very high, low, or distorted

line voltage..

Reduce the load on the UPS by
unplugging equipment and reset the
circuit breaker(on back of UPS) by
pressing the plunger back in.
Move the UPS to a different outlet on a
different circuit.

UPS beeps occasionally.

• Normal UPS on battery

operation.

None. The UPS is protecting the load.

UPS does not provide expected backup time.

• The UPS’s battery is weak

due to recent outage or is
near the end of its service
life.

• The UPS is overloaded. Check the UPS’s load display. Unplug

Charge the battery. Batteries require
recharging after extended outages.
Also, they wear faster when put into
service often or when operated at
elevated temperatures. If the battery is
near the end of its service life, consider
replacing the battery even if the replace
battery indicator is not yet lit.

less needed equipment, such as printers.

All indicators are lit and UPS emits a constant beeping.

• Internal UPS fault. Do not attempt to use the UPS. Turn

the UPS off and have it serviced
immediately.

Overload indicator is on and beeps constantly.

• UPS is overloaded. Unplug less needed equipment, such as

printers.

The replace battery light is lit.

• Weak batteries. Do another self test to see if it clears.

• Replacement batteries not

connected properly.

Confirm the battery connections.

Safety

This section contains important instructions that should be followed during installation and maintenance of the PowerStack 450 and
batteries. It is intended for customers who setup, install, relocate, or maintain APC equipment.

Electrical Safety

• Do not work alone under hazardous conditions.

• High short circuit current through conductive materials could cause severe burns.

• Check that the power cord(s), plug(s), and sockets are in good condition.

• To reduce the risk of electric shock when grounding cannot be verified, disconnect the equipment from the AC power outlet before

installing or connecting to other equipment. Reconnect the power cord only after all connections are made.

• Do not handle any kind of metallic connector before the power has been removed.

• Use one hand, whenever possible, to connect or disconnect signal cables to avoid a possible shock from touching two surfaces with

different electrical grounds.

• Connect the equipment to a three wire AC outlet (two poles plus ground). The receptacle must be connected to appropriate branch

circuit/mains protection (fuse or circuit breaker). Connection to any other type of receptacle may result in a shock hazard.

CAUTION! Deenergizing Safety

• If the equipment has an internal energy source (the battery), the output may be energized when the unit is not connected to an AC

power outlet.

• To deenergize: first press the Off button for more than one second to switch the equipment off. Next disconnect the equipment

from the AC power outlet. Finally, disconnect the battery.

• Pluggable equipment includes a protective earth conductor which carries the leakage current from the load devices (computer

equipment). Total leakage current must not exceed 3.5 mA.

• Use of this equipment in life support applications where failure of this equipment can reasonably be expected to cause the failure

of the life support equipment or to significantly effect its safety or effectiveness is not recommended.

WARNING! Battery Safety

• This equipment contains potentially hazardous voltages. Do not attempt to disassemble the unit. The only exception is for

equipment containing batteries. Battery replacement using the procedures below is permissible. Except for the battery, the unit
contains no user serviceable parts. Repairs are performed only by factory trained service personnel.

Batteries must be recycled. Deliver the battery to an appropriate recycling facility or ship it to the supplier in
the new battery’s packing material. See the new battery instructions for more information.

• Do not dispose of batteries in a fire. The batteries may explode.

• Do not open or mutilate batteries. They contain an electrolyte which is toxic and harmful to the skin and eyes.

• To avoid personal injury due to energy hazard, remove wrist watches and jewelry such as rings when replacing the batteries. Use

tools with insulated handles.

• Replace batteries with the same number and type of batteries as originally installed in the equipment.

Handling Safety

⇒ <18 kg (<40 lb.)

⇒ 32-55 kg (70-120 lb.)

⇒ 18-32 kg (40-70 lb.)

• Be careful. Do not lift heavy loads without assistance.

• Equipment with casters is built to move on a smooth surface without any obstacles.

⇒ >55 kg (>120 lb.)
