Electrical Installation
Connection of system input
1. 3-in 3-out, common input configuration (default)
Connect the main input terminals (mA-mB-mC-N) and bypass input terminals (bA-bB-bC-N), and then
parallely connect them to the main input terminals as shown in Figure 3-1 . Ensure correct phase rotation.
The shorting cables of common input configuration were assembled before delivery, no need to reinstall
them again.
2. 3-in 3-out, split bypass configuration
Remove the bypass input cables (bA-bB-bC) connected to the main input terminal. Connect the bypass
input cables to the bypass input terminal (bA-bB-bC). Ensure correct phase rotation. Ensure that the main
input cables (mA-mB-mC) are connected to the main input terminal correctly and reliably.
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 3-1 for the torque value. Ensure correct phase rotation.
Warning
If there is no requirement of power supply for the load before arrival of the service engineer, ensure that the system out-
put cables are safely isolated at their ends.
Connection of batteries
If external batteries are required, 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 (see Figure 3-1 ), i.e., (+) to
(+) and (-) to (-), (N) to (N), and 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.
• When connecting the cables between external battery terminals and BCB, the connection should
begin from the BCB terminal.
