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.
