Operating Procedures
This chapter defines the operating procedures to be followed to activate, deactivate and manage the UPS.
The instructions shall be applied with the sequence, in which they are written.
5th1
Commissioning
Make the connections according to the installation section.
Switch the circuit breaker on the input distribution panel “ON” / “I”.
Switch the circuit breaker on the by-pass distribution panel “ON” /”I”.
If the by-pass mains input is separated, bring the by-pass circuit breaker (F4) to “ON”/ “I” position.
Bring the input circuit breaker (F1) and inrush circuit breaker (F6) to “ON”/ “I” position.
Bring the output circuit breaker ( F2 ) to “ON” / “I” Position.
Wait for the LCD to start up. Set the date and time.
See the “NORMAL” message on the LCD.
Bring the circuit breaker of the external battery cabinets to “ON”/ “I” position.
Bring the battery circuit breaker (F5) to “ON”/”I” position.
The UPS starts up in bypass mode and automatically switches to normal mode. “NORMAL”
message
will
not
be
displayed,
until
the
UPS switches to normal mode.
Frequency/waveform/rms value of the bypass mains voltage shall be in acceptable limits and
bypass shall be enabled for the UPS to start-up. Voltage and frequency of the mains input shall be
in their tolerance limits, and both the rectifier and the inverter shall be enabled for the UPS to
operate in normal mode.
5th2
Decommissioning
Bring the output circuit breaker (F2) to “OFF”/”0” position.
Bring the input, inrush and manual by-pass circuit breakers (F1, F6 and F3) to “OFF”/”0” position.
If the by-pass mains input is separated, bring the by-pass circuit breaker (F4) to “OFF”/”0” position.
Bring the battery circuit breaker (F5) to “OFF”/”0” position.
Bring the circuit breaker of the external battery cabinets to “OFF”/”0” position.
Switch the circuit breaker on the input distribution panel “OFF” / “0”.
Switch the circuit breaker on the by-pass distribution panel “OFF” / “0”.
In the event of an extended period of UPS inactivity, the batteries must be charged periodically
in order to prolong battery life. The charge period, which depends on the temperature, is given
in the “storage” section of the manual.
