Configuring the Neutral/Earth Jumper
The UPS contains an isolation transformer that generates a neutral conductor for the connected load.
The UPS is a separately derived source and contains a neutral/earth jumper. A factory-installed
neutral/earth jumper copper bar may require removal to comply with local codes and regulations.

Connecting Cables
To connect the cable:
1. Remove the knockouts at the junction box (see
Figure 37
) and pull the cables through them,
leaving some slack for installation.
Figure 37 Knockouts
2. Connect the cable to the corresponding terminal of the power input and output terminals. Using a
torque wrench, tighten the screws to 4.52 Nm (40 in-lb). The connections are shown in
Figure 38
.
NOTE
Input and output cables must be run in separate conduit before cable connection.
