11.5Grounding Configuration

This section describes the grounding configuration to be used with this UPS.

A 2 AWG (or 38 mm2) factory-installeded jumper cable is provided between the neutral terminal and ground bus in the UPS cabinet. The jumper cable location is illustrated below.

FIGURE 11.9 - JUMPER CABLE BETWEEN THE NEUTRAL TERMINAL & GROUND BUS

Since the input source is a delta-connection (3-phase 3-wire) without ground, the neutral terminal in the UPS cabinet must be connected to the ground bus with the internal jumper cable as shown in Figure 11.9.

The jumper cable should stay in place. See Figure 11.9 for the jumper cable location.
