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.
 When the EPO switch is in the NC state, remove the jumper between EPO_NC and EPO_12V
before connection. When the EPO switch is turned off, EPO is triggered.
