EPO
EPO (Emergency Power Off) is a mechanism that cuts off energy supply to
receivers at the UPS output in extreme situations (e.g. a fire).
The mechanism may be activated by short-circuiting the pins of the external EPO
connector (trip).
If the unit was in mains operation mode, it switches to zero mode (STANDBY). If, in
turn, the unit was in battery operation mode, it is switched off. Input voltage is
reinstated only after the user manually removes the EPO short circuit. If the unit is in
zero mode (STANDBY), signalling can be turned off by pressing the “OFF” button;
the unit then switches to BYPASS mode. Only then is it possible to power on the unit
When the unit is switched off and the short circuit in the EPO circuit has been
rectified, the unit may be powered on using the standard procedure.
The EPO connector pins have a safe voltage that is separated from the remaining
systems of the device.
NOTE! The EPO circuit must be a separate circuit and it is forbidden
to connect it to other systems.
COMMUNICATION BETWEEN THE UPS AND A COMPUTER
RS232 COMMUNICATION
POWERLINE series battery back-ups come with enhanced control features. The user
can work with a RS232 communications port or optionally an Ethernet port (for back-
ups equipped with SNMP card). In order to ensure correct cooperation the battery
back-up must be connected to the computer with the provided cable. After the cable
is connected, start the back-up, start the computer and install the software in
accordance with the instruction manual or the instructions provided by the PowerSoft
installation software (which can be downloaded free of charge from www.ever.eu) or
WinPower.
