Connection of system input
1.
Common input configuration
Connect the AC input cables to the bypass input terminals (bA-bB-bC) in the cabinet and ensure that the
shorting copper bars between the rectifier input terminals and the bypass input terminals are connected
correspondingly. Connect the input neutral line to the neutral terminal N in the cabinet. Ensure correct phase
rotation.
2.
Split bypass configuration
Remove the shorting copper bars, 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 40 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 (BAT+, N, BAT-) in the UPS cabinet, that is, (BAT+) to (+) and (BAT-) 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.
