FUNCTION
1,2,3
RL 1
OUTPUT 1
Bypass / fault, the contact changes position when the UPS switches the
load onto the bypass line either during normal operation (e.g. due to
overload) or as a result of a fault in the inverter stage.
See Note below
4,5,6
RL 2
OUTPUT 2
Battery discharging, the contact changes position when the load is
powered from the battery due to a mains power failure
7,8,9
RL 3
OUTPUT 3
End of battery discharge, the contact changes position when, during a
mains outage, the remaining time for battery discharge has reached the
minimum value defined. Once this time has passed, the load will remain
unpowered (the factory-set end of discharge pre-alarm value is 5 minutes)

INPUT 1
Inverter OFF. Connect pin 11 to pin 12 (for at least 2 seconds).
- In “NORMAL OPERATION”,
If the INVERTER OFF command is received, the UPS switches the power
supply of the load onto the bypass line (load is not protected in case of a
mains outage).
- In “EMERGENCY OPERATION”,
If the STOP INVERTER command is received, the UPS shuts down (load
is not powered).
See Note below

EPO
INPUT
EPO
If the jumper on the connector is opened, the UPS will shut down.
The UPS is factory-fitted with the EPO terminals short circuited. If this input
is used, the UPS can be shut down in a hazardous situation from a remote
position simply by pressing a button.
Warning: if only the mains power supply is removed, for example by opening the switch of the power
supply panel, as a means for shut down the UPS in an emergency the UPS will keep the load
powered using the energy stored in the batteries.
Other functions of the three relays and the commands may be programmed via the display panel. The ALARMS and the
COMMAND are factory-set in the following way:
