Installation and Operating Instructions
UPS Edition One 1kVA, 2kVA, 3kVA
Emergency Power Off (EPO)
EPO is used to shut down the UPS remotely. This function can be used to shut down
the load and the UPS through a thermal relay, e.g. in case of room overtemperature.
When EPO is activated, the UPS immediately switches off the output and all its current
transformers. The UPS remains switched on to report the fault.
EPO-connections
NOTE:
Depending on the user configuration, the pins must be short-circuited or opened
for the UPS to continue running. To restart the UPS, reconnect the pins of
the EPO connector (open them again) and switch on the UPS manually. The
maximum resistance in the shorted loop is 10 ohms.
Always test the EPO function before applying your critical load to avoid
accidental loss of load.Leave the EPO plug installed on the EPO connector of the
UPS even if the EPO function is not needed.
Load Segments
Load segments are sets of receptacles that can be controlled by power management
software or through the display, providing an orderly shutdown and startup of your
equipment. For example, during a power outage, you can keep critical equipment running
while you turn off other equipment. This feature allows you to save battery power.
