Safety: IMPORTANT SAFETY INSTRUCTIONS - SAVE THESE INSTRUCTIONS

User Safety
WARNING!
User functions: For safety reasons the user may only
- Remove the finishing panels for air filter exchange
- Operate the UPS display.
WARNING!
The UPS can be powered from more than one source.
CAUTION!
The system is equipped with an optional auto-start function, enabling the system to start
without any warning when power is applied.

Note

Typically, the UPS installation will be connected to an EPO (Emergency Power Off)
button located on a wall near the entrance to the room. If activated, the EPO switches off
power to the UPS, disconnects the UPS output, and switches off power to the entire
room. This action will disconnect support to the load if the UPS is online.

• Battery monitor test: Setting this value to True results in an automatic battery monitor test being
performed at regular intervals specified by the Service Engineer. The three options are:
– Auto battery test - every (N) week(s).
– Auto battery test - on one day of the week.
– Auto battery test - at a specific time of the day.
• Battery capacity test: Setting this value to True results in the batteries being discharged until a
Battery Low Voltage Level is reached. This test can only be performed manually. The test is
used to cycle the batteries in order to calibrate the backup time with the current load and battery
modules installed.
• Battery monitor reset: In the event of a weak battery or another battery problem, use this button

Operation Modes
On-line Operation
During on-line operation, the critical load is supported by the inverters. The main inverter controls
the output voltage and the delta inverter controls the input current. The delta inverter also provides
battery-charging current. While the UPS is running in this mode, a single-line diagram will appear on
the screen. The green line indicates the power flow from the utility supply through the UPS to the
load.
CAUTION!
Do not open Q2 when the UPS is in on-line operation, as this action may result in a load
drop or a failure of the UPS to support the load.

During battery operation, the load is supported by the inverters. The inverters are supplied by battery
power, ensuring uninterrupted support to the load.
While the UPS is running in battery operation, a single-line diagram will appear on the screen with a

long as the batteries are energized.
