11.7.2Grounding Configuration (without input neutral)

When the input source is wye-connected, the neutral line out to the bypass input should be left open. The UPS is grounded by connecting the neutral terminal to the ground bus with the internal jumper cable. See Figure 11.18.

The jumper cable should stay in place. See Figure 11.17 for the jumper cable location.

If a ground fault interrupter is installed, the UPS is likely to trip the interrupter during transferring to/from the bypass circuit. It is recommended that the ground fault interrupter be set to a minimum delay of 0.5 seconds.

11.7.3Recommended Configuration (for delta-input)

If 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 11.19.

The jumper cable should stay in place. See Figure 11.17 for the jumper cable location.
