Powerware 9315s manual Table N. Remote EPO, Remote Emergency Power OFF

1.The Remote EPO feature shuts down the UPS modules, opens all breakers in the Switchboard System Bypass Module and isolates power from your critical load. Local electrical codes may also require tripping upstream protective devices to the UPS modules.

2.To open all UPM breakers, a separate twisted pair of wires and an EPO Kit (sold separately) must be installed to the modules from the SSBM.

3.Use Class 1 wiring methods (as defined by the NEC) for control wiring. Install the control wiring in separate conduit from the power wiring. The wire should be rated at 24 volts, 1 amp minimum.

4.Refer to Table N of this drawing and to applicable chapters for information about installing control remote EPO.

5.Refer to drawings 164201373---4 and 164201373---13 for location of the Customer Interface panel and drawing 164201373---4 for the terminal block location on the Customer Interface Panel.
