6.7 Connecting a Remote EPO Switch
NO TICE
● 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
protect the cable with a protective tube.
● Triggering EPO will shut down the rectifier, inverter, charger, and static bypass,
but will not disconnect the UPS mains input. To power off the UPS completely,
turn off the upstream input switch when you trigger EPO.
Use a cable to connect the EPO switch to the dry contact port on the control
module of the UPS.
