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!
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.
Read and pay attention to this important information.
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 are recyclable. Please save for later use or dispose of them appropriately.

Introduction
1.0Introduction
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.
1.1Display 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.

WARNING!
AC voltage generated either from batteries or utility may be present at UPS output.
Always disconnect AC input supply source, switch off UPS, AND switch off DC.
TEST BEFORE YOU TOUCH!
Some UPS systems have a factory-set autostart feature, automatically switching on UPS
whenever utility supply is switched on (AC line). See section 4.0 Parameter settings for
instructions on how to switch off this function.
Only qualified electricians should start up or shut down APC Silcon UPS systems and
instructions in the Installation Guide should be followed. Prior to being serviced, the APC
Silcon UPS must be left in shut-down mode for a minimum of 5 minutes.
CAUTION!
Refer to the Maintenance & Testing section in this guide if the UPS is to be taken out of
operation for more than 48 hours.
Users without electrical qualifications may switch UPS to and from stand-by-mode/normal
operation, following instructions below. ( In stand-by mode, the UPS has no output
voltage ).

WARNING!
TEST BEFORE YOU TOUCH!
A special design feature switches the system into bypass operation in the event of internal power
supply failure or controller circuit failure to ensure uninterrupted output voltage.
Because of this special feature, the UPS may contain output voltage even when it is switched off.

The UPS is now isolated. Maintenance/repair, disconnection or removal can now be carried out.
CAUTION!
Recharge batteries out of service every 3 months to prevent damage.
WARNING!
Internal DC capacitor may contain energy even after the UPS has been switched off. Allow for
automatic discharge by waiting at least 5 minutes after switching off UPS and battery breakers
before working on the UPS.
2.4Start UPS (from complete power down)
2.4.1 UPS start-up
CAUTION!
Make sure all cable connections are in place prior to first start-up.
NOTICE!
After first system start-up, check that battery temperature is displayable (press and
simultaneously on the display – it reads NV (not valid) if incorrectly installed). A battery capacity
test is recommended after the electric installation.
NOTICE!
If for any reason the start-up procedure is interrupted, wait for the display to show the step 4
message: “Stop charge DC capacitors : YES” and repeat procedure from there.
CAUTION!
Do not close the MCCBs in the Battery Breaker Box unless the display reads: “Insert fuse or
close MCCB” – otherwise the UPS may be damaged. If the display reads “DC capacitor charge
error”, do not close MCCB.
Call for assistance.
WARNING!
If “Autostart” is active the UPS will start automatically after step 9 (with a 1-minute delay)
