User Safety
WARNING!
This UPS contains hazardous AC and DC voltages. Only qualified electricians
should connect the UPS, AC line and external batteries, and must be familiar with
batteries and battery installation.
Before installing, maintaining or servicing the UPS, shut off the UPS and
disconnect all sources of AC and DC power.
As the UPS has no built-in disconnection devices to switch off external AC and DC
input power, ensure that disconnection devices are available as separate parts in
connection with the installation!
AC and/or DC voltage will always involve a potential risk of AC voltage at UPS
output generated from either batteries or utility. To avoid equipment damage or
personal injury, always assume that there may be voltage at UPS output.
This system is equipped with an auto-start function. If activated, the system may
start without warning. Refer to the “Programming” section for information on deactivation.
The installer must provide each external disconnecting device for this UPS system
with labels with the following text:
“Isolate the Uninterruptible Power Supply (UPS) as instructed in this guide before
working on circuit”
Caution
WARNING!
TEST BEFORE YOU TOUCH!
To reduce the risk of fire or electric shocks, install the UPS and external batteries
in a temperature and humidity controlled indoor area, free of conductive
contaminants.
WARNING!
UPS batteries are high-current sources. Shorting battery terminals, DC terminals
or DC busbars can cause severe arcing, equipment damage and injury. A short
circuit can cause a battery to explode. Always wear protective clothing and eye
protection and use insulated tools when working on batteries.
CAUTION!
This unit contains components sensitive to electrostatic discharge (ESD). If you do not
follow the ESD procedures, you may cause severe damage to electronic components.

Site Requirements
Receiving and inspecting the UPS
Your AIS 5000 UPS system has been tested and inspected for quality assurance prior to shipment
from APC. To ensure that the UPS has not been damaged during transportation, carefully inspect both
the exterior and interior of the equipment immediately upon receipt as described in the Receiving and
Unpacking folder.
Type label. Copy type label data (serial number) to label copy below for easy identification of the
system. The type label is placed on the inside of the UPS front door.

990-2440AIS 5000 400V Installation Manual4
General Information - Site Requirements
Moving the equipment to site:
Before moving the equipment to the installation site, the following should be checked:
• Can the transport equipment handle the weight of the system?
• Is there enough space to transport the system to its final destination?
• Can the raised floor (double floor) handle the weight of the system?
The equipment is delivered on a pallet and can be transported on a fork-lift or a pallet truck.
The UPS is contained in a cubicle with a stable frame. This frame can carry heavy components such
as transformers, chokes etc. The frame can be placed directly on a levelled concrete floor.
Clearance at installation site. The system can be installed with the back to the wall or back-to-
back - however, a distance of minimum 4 inches (approx. 100 mm) between the wall and the UPS is
necessary. 20 inches (approx. 500 mm) is the preferred distance (see below illustration).
A clearance of 20 inches (approx. 500 mm) above the system is necessary to ensure sufficient space
for air circulation.
UPS
Clearance; minimum 100 mm – preferably 500 mm.

990-2440AIS 5000 400V Installation Manual5
Air Filter
The air filter must be fitted at the air inlet of the UPS, and is designed for extra protection of UPS
systems installed in environments with conductive dust.
Fitting the air filter
Insert the air filter in the brackets and slide it completely into the UPS enclosure.
The air filter can be mounted/replaced during normal operation of the UPS.

Operation Modes
The display automatically indicates the current UPS operation mode. See the table below for
examples of operation modes and their descriptions.
Operation mode descriptions:
Operation ModeDescription of Operation Mode
Normal OperationThe inverter supplies the load. The charger uses the mains supply to feed the
inverter.
Battery OperationThe inverter supplies the load. The battery bank supplies the inverter. In battery
operation the load support time is limited; when the batteries are discharged the
UPS is unable to supply the load.
Bypass OperationThe bypass static switch supplies the load, meaning that the load is supplied
directly from the bypass mains. When working in bypass operation the UPS can
switch to battery operation if the bypass mains fails.
