3.6 Installing a remote EPO switch

NOTE

Remove the UPS cabinet interface entry plates to punch holes (see Figure 3-3).

NOTE

This switch must be a dedicated switch not tied into any other circuits.

NOTE

This procedure is intended to be used for the installation of the Powerware remote EPO switch. If installing another manufacturer’s switch, only use this procedure as a guide.

A remote EPO switch can be used in an emergency to shut down the UPS and remove power to the critical load from a location away from where the UPS is installed. Figure 3-12 shows a remote EPO switch.
