Installation Information

11.The Remote EPO feature opens all contactors in the UPS cabinet and isolates power from your critical load. Local electrical codes may also require tripping upstream protective devices to the UPS.

12.A jumper wire must be connected between pins 8 and 9 on TB1, if the normally-closed EPO contact is not used.

13.Remote EPO wiring should be a minimum of 22 AWG.
