Safety Symbols used in this manual
WARNING! Indicates a hazard which, if not avoided, could result in injury or death.
CAUTION! Indicates a hazard which, if not avoided, could result in damage to the product or
other property.
NOTICE!
Read and pay attention to this important information.
WARNING!
This UPS unit 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!
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”
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 de-activation.
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.
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.
PLEASE RECYCLE
The shipping materials for the APC Silcon UPS are recyclable. Please save for later use or dispose of
them appropriately.

Introduction
1.0 Introduction
This UPS system is designed to offer reliable and problem-free power supply for several years.
The system requires only a minimum of maintenance, but we recommend you follow the
maintenance guidelines described in Section 6.0 Maintenance & Testing.
1.1 Display Unit
The display unit (located on the front of the UPS) is the link between the user and the UPS and
consists of a display, an alarm LED indicator and a keyboard. The display reads parameters,
measured values and alarm messages. Alarms and the pressing of keys will activate a back
light which is set to switch off automatically after 5 minutes of inactivity.
By pressing and simultaneously you increase the back light contrast. The pressing of
and simultaneously decreases the contrast.
The LED alarm is linked to an acoustic signal indicating incorrect operation. Alarms will
change the LED light from green to red. Use keyboard to program operating parameters and
to display parameters / alarm messages.
