Single-unit UPS
◗green "load protected" light 5 goes off,
◗red "load not protected" light 2 on the control panel goes on,
◗the inverter stops;
◗if transfer to Mains 2 conditions are correct, the inverter shuts down and the load is transferred to Mains 2;
◗if transfer to Mains 2 conditions are not correct, the inverter does not shut down;
◗special action on the hidden control panel is required to force inverter shutdown,
◗to force inverter shutdown, press
simultaneously the security button 14 and button 5 "Forced inverter shutdown" 17 on the hidden control panel,
◗the load is transferred to Mains 2 with a 0.8 second interruption in the supply of power.
Multi-bypass modular UPS:
◗the UPS shuts down (the other
◗green "load protected" light 5 goes off,
Modular UPS with external maintenance bypass:
◗all the UPSs shut down:
◗green "load protected" light 5 goes off,
◗red "load not protected" light 2 on the control panel of each unit goes on,
◗orange "operating problem" light 3 on the other units goes on, all shut down due to the overload.
Frequency converter:
◗if the system is redundant, i.e. the other
◗green "load protected" light 5 goes off,
◗red "load not protected" light 2 lights on the control panel of the line; The load is not affected in that the other inverters continue to supply it normally;
◗if the system is not redundant, all the inverters shut down;
◗green "load protected" light 5 goes off,
◗red "load not protected" light 2 on the control panel of each line goes on,
◗orange "operating problem" light 3 on the control panel of the other lines goes on, all shut down due to the overload.
Parallel UPS with SSC:
◗if the system is redundant, i.e. the other
◗green "load protected" light 5 goes off,
◗red "load not protected" light 2 lights on the control panel of the line. The load is not affected in that the other inverters continue to supply it normally;
◗if the system is not redundant and the transfer to Mains 2 conditions are correct, all the inverters shut down;
◗green "load protected" light 5
goes off,
◗ red "load not protected" light 2 lights on the control panel of each line,
◗orange "operating problem" light 3 on the control panel of the other lines goes on (all shut down due to the overload),
◗the load is transferred to Mains 2 without an interruption in the supply of power;
◗if the system is not redundant and the transfer to Mains 2 conditions are not correct, the inverter does not shut down;
◗special action on the hidden control panel is required to force inverter shutdown,
◗to force inverter shutdown, press
simultaneously the security button 14 and button 5 "Forced inverter shutdown" 17 on the hidden control panel,
◗the load is transferred to Mains 2 with a 0.8 second interruption in the supply of power.
◗red "load not protected" light 2 on the control panel goes on.
The load is not affected and continues to be supplied by the other unit.
Shutdown of an rectifier/charger
Except in frequency converters without a battery, it is recommended not to stop the rectifier/charger because the battery will no longer be charged. Except in the case of a test of the inverter on battery power, the rectifier/ charger should be shutdown after the inverter to avoid unnecessary battery discharge.
Proceed in the following order:
◗open battery circuit breaker QF1;
◗open Mains 1 input switch Q1;
◗the rectifier/charger shuts down,
◗all control panel lights go off because the device is powered down.
Note:
In a frequency converter without a battery, rectifier/charger shutdown automatically results in inverter shutdown.
