3.3.6 Connecting a Remote EPO Switch
● The Company does not provide the EPO switch or cable. Prepare them by
yourself. The recommended cable size 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
rectier, inverter, charger, and static bypass,
but does not disconnect the UPS mains input. To power
o the UPS completely,
open the front-end input switch when triggering EPO.
Connect the requisite EPO switch to UPS dry contacts.
● Figure 3-39 shows the cable connections for an NC EPO switch.
