(Optional) Connecting an EPO Switch
1. For UPS2000-G-15KRTL-
01/UPS2000-G-20KRTL-01, choose
Settings > System Parameters >
Other Settings and set EPO Enable
to Enable.
2. Connect an external switch to the
EPO ports of the UPS. After you
turn on the switch in the case of
emergency, the inverter stops and
the UPS does not transfer to bypass
mode. In this way, the UPS stops
supplying power immediately.
3. The customer provides the external
switch (it can be a common switch)
that connects to the EPO ports.
