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.

WARNING!
AC voltage generated either from batteries or mains 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 mains 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 ).

3.4 Economy Mode
When the UPS is running in Economy Mode, the load will be supplied directly from mains and
output voltages are UPS monitored. In the event of a mains disruption, the UPS will switch to
battery mode without affecting the load.
Prior to switching to bypass mode, leave the system running in normal mode for 8-10 hours to
charge batteries to full capacity.
To keep batteries fully charged, UPS is pre-programmed to switch back to normal operation
whenever necessary.
Economy Mode not available for parallel configurations.
At start-up, the system will at first go into normal operation to ensure a fully charged battery,
and it will then switch into bypass after the programmed time (8-10 hours).
NOTICE!
Check cable dimensions as input power factor is not corrected with UPS running in Economy
Mode.

5.4 Rectifying Alarm Messages
Following actions may rectify alarm:
• Check local mains supply. Fuses may be blown or supply switched off accidentally
• Check if UPS cooling air intake is blocked
• Check if load exceeds maximum output capacity
• If, with mains power switched on, there is no UPS output voltage - and an attempt
to restart the UPS is in vain - use the external service bypass switch to bypass UPS
1. “Battery weak” message appears: Reset “battery weak” signal according to section 4.0
Parameter Settings and initiate battery capacity test according to Section 6.3. Battery
Capacity Test. Make a record of obtained back-up time and use battery monitor to reset
alarm. Leave the UPS to recharge battery for at least 16 hours. Start up second battery test
without changing the load. If the test result shows improved back-up time, continue the test
series until no or just insignificant improvements are obtainable. If battery is still weak call for assistance.
2. “Battery Defective” message appears: Call for assistance. See section 8.0 “How to contact
APC”.

5.5 Parallel Operation Alarms
The parallel operation alarm message is: Communication to parallel IF lost
In the event of a parallel operation alarm, all parallel operation functions controlled by
Advanced Power Management will be inactive. In such situations only simple hardware control
such as load-sharing, operation mode etc. is possible.
Correction of false alarm situations during service:
When one system is isolated for service, the above alarm message will apppear if two systems
still operating. To delete this alarm message re-program the station addresses on all systems
in the following sequence:

Maintenance & Testing
6.0 Maintenance & Testing
UPS maintenance should be carried out by trained service engineers only. Service and
maintenance contract is recommended.
6.1 Fan
It is recommended to replace fans every 3 years.
6.2 Battery Monitoring Test
Systems with built-in batteries have a standard battery monitoring feature (optional in other
systems).
Battery Test Results:
1. Battery OK. Back-up time normal.
2. Reduced battery capacity - “Battery weak” message appears.
3. Battery capacity too low - “Battery defective” message appears.
Carry out battery monitoring test by discharging max. 25% of battery energy. For systems with
no battery monitor/no excess back-up time, a battery capacity test is recommended every 6
months.
Carry out battery tests when load is least affected.
6.3 Battery Capacity Test
CAUTION!
Allow 16 hours to restore full back-up time after battery capacity tests.
