To prevent electrical shock or damage to the equipment, verify that the Eaton 9170+ UPS is OFF before you remove the entrance panel. The circuit breaker or disconnect switch must also be OFF at the AC input service panel.

To install the UPS without an external bypass switch:

1.Unscrew and remove the rear cover(s) of the UPS (top cover on 3- or 6-slot; top two covers on 9- or 12-slot). See Figure 26.

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 26.

Wiring for optional emergency power-off (EPO) 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 8 and 9 on page 47.
