3.7.6 Remote EPO

 Huawei does not provide the EPO switch or cable. If the cable is required, 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, open the front-end
input switch when triggering EPO.
Connect the requisite EPO switch to UPS dry contacts.
