
Huawei does not provide the EPO switch or cable. Prepare them by yourself. The
recommended cable is 22 AWG.

Equip the EPO switch with a protective cover to prevent misoperations, and cover the
cable with protective tubing.

Triggering EPO will shut down the rectifier, inverter, charger, and static bypass, but does
not disconnect the UPS mains input. To power off the UPS completely, turn off the
front-end input switch when you trigger EPO.
Connect the EPO switch to specified dry contacts on the UPS. Figure 3-65 uses the
UPS5000-A-30 kVA/40 kVA UPS as an example.
By default, the EPO switch is NO. When you turn on the EPO switch, EPO is triggered.
