Follow-up Procedure
After connecting cables, reinstall the covers of the power distribution subrack, rear panel,
and side panel of the bypass cabinet.
After connecting cables, check that a certain clearance is reserved between the internal
switch (if any) extension pole and power cables to avoid friction.
3.2.8 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.
