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
