EPO
The Remote Emergency Power Off (Remote EPO) mechanism cuts the power supply
from the UPS output to loads in extreme situations or in emergency (e.g. fire).
The mechanism can be activated by the means of opening contacts of the external
EPO connector (a trigger).
Figure 10: EPO triggering signaling
If EPO is triggered when the UPS unit operates in Line mode, the unit will switch to
STANDBY mode. However, if EPO is triggered when the UPS unit is in BATTERY
mode, the unit will switch off completely. The output is switch again only after the
user's intervention (the EPO circuit is reset and the UPS unit is restarted).
If the UPS unit is in STANDBY mode, EPO signaling is switched off by pressing the
OFF button. The UPS unit switches to BYPASS mode, which is a precondition to
restart the unit.
When the UPS unit is OFF, once the EPO circuit is reset, the unit can be restarted
following the standard procedure.
The EPO connection contacts show safe voltage levels isolated from the remaining
UPS unit systems.
CAUTION!
The EPO circuit must be a separate circuit and it is forbidden
to connect it with other installations.
