Refer to Figure 4.2 on page 38 to Figure 4.3 on the previous page, open the front door of the UPS, and remove the protective
cover to reveal the power cable connection terminals (see Figure 4.3 on the previous page). Connect the protective earth
cable to the PE input terminal in the cabinet.

Connection of system input
1. Common input configuration
Connect the AC input cables to the bypass input terminals (bA-bB-bC) in the cabinet. Connect the input
neutral line to the neutral terminal N in the cabinet. Ensure correct phase rotation.
2. Split bypass configuration (factory default)
Connect the rectifier input cables to the rectifier input terminals (mA-mB-mC) in the cabinet, and connect the
bypass input cables to the bypass input terminals (bA-bB-bC) in the cabinet. Connect the rectifier input
neutral line and bypass neutral line to the neutral terminal N in the cabinet. Ensure correct phase rotation.
Connection of system output
Connect the system output cables between the output terminals (oA-oB-oC-N) in the cabinet and the load. Refer to Table
4.1 on page 34 for the torque value. Ensure correct phase rotation.

Connection of batteries
Ensure correct polarity of the connections from the battery string terminals to the BCB and from the BCB to the battery
input terminals (+, N, -) in the UPS cabinet, that is, (+) to (+) and (-) to (-), (N) to (N), but disconnect one or more battery cell
links in each tier. Do not reconnect these links and do not close the BCB before authorized to do so by the service engineer.
