Control panel
Forced transfer to inverter with load interruption
Forced inverter shutdown with load interruption
Light A - emergency shutdown
Light B - rectifier-charger on
Light C - rectifier-charger fault
Light D - Mains1 outside tolerances
Light E - battery room ventilation fault and/or harmonics filter temperature outside tolerances
Light F - battery temperature outside tolerances
Light G - battery charging
This button transfers the load to the inverter. If the transfer conditions (Mains 2 characteristics outside tolerances) are
not correct, the transfer will result in a 0.8 second interruption in the supply of power to the load.
Note:
– for parallel-connected modular UPSs, forced transfer of the load will not take place if the number of operating UPSs
required by the load is greater than one;
– for parallel UPSs with centralised SSC, this function is available only on the SSC.
This button :
– transfers the load to Mains 2;
– shuts down the inverter.
It may be used if the transfer conditions (Mains 2 characteristics outside tolerances) are not correct, in which case the "inverter
off" button on the visible control panel produces no effect;
– is disabled on the SSC.
This red light signals that the remote "emergency shutdown" button was pressed (external information received and stored
in memory).
This green light indicates that the rectifier-charger is on.
This red light is an alarm stored in memory signaling a rectifier-charger fault. It can signify one or several of the following faults:
– input switch Q1 open;
– RC input protection fuse (FU1-2-3) blown;
– RC internal over-temperature;
– battery charge over-current;
– battery over-voltage;
– RC electronic control board faulty, not calibrated or not personalized;
– power supply board fault.
This yellow light signals that the Mains1 voltage and/or frequency characteristics are outside tolerances.
This yellow light is an alarm stored in memory signaling a battery room ventilation fault (external information that must be
supplied from the room).
If the installation includes a harmonics filter, this light will also signal an overtemperature of the filter’s inductor (information
supplied).
This yellow light signals that the battery temperature is outside tolerances (external information supplied by special board
("Temperature Monitor" option).
This yellow light signals that the battery is being recharged (vented batteries only). This light is deactivated in systems with
sealed lead-acid batteries.
