● 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
rectier, inverter, charger, and static bypass,
but will not disconnect the UPS mains input. To power o the UPS completely,
turn o the upstream input switch when you trigger EPO.
Connect the EPO switch to the dry contact on the UPS using a cable.
