3. Remove the rear panels of the UPS (top panel on 3- or 6-slot;

top 2 panels on 9- and 12-slot) as shown in Figure 21.
The entrance panel contains knockout openings for entrance

and exit conduits and for conduit to an optional external

battery cabinet. The entrance panel is located on the top 3-slot

section for 3- and 6-slot cabinets; on the second section for 9-

and 12-slot cabinets as shown in Figure 21.
Wiring for optional EPO and bypass input signals passes

through the opening at the top back of the cabinet. Wiring for

an optional generator input signal must pass through a separate

opening. Installing this wiring is described in Steps 11 and 12.

4. Remove the knockouts in the entrance panel for AC input and

AC output wiring.
