Electrical Installation
Procedures
1. Two protective covers exist at the rear of the cabinet. The user can process a cabling hole on the No.1
protective cover for routing the cables according to actual needs.
Note: The guard ring or flange must be installed around the cabling hole so that the cables are not cut.
2. Dismantle the No.2 protective cover.
3. In split bypass configuration, just lead the main input cables (mA, mB, mC, N, PE), bypass input cables (bA,
bB, bC, N, PE), and output cables (oA, oB, oC, N, PE) in the cabinet through corresponding cabling hole. Refer
Figure 3-1 to connect power cables to corresponding terminals and fix PE cable to PE terminal. In common
input configuration, just lead the main input cables (mA, mB, mC, N, PE), and output cables (oA, oB, oC, N,
PE) in the cabinet through corresponding cabling hole.
4. If the user adopts external battery, just lead the battery cables in the cabinet through the reserved cabling
hole at top of the routing area. Refer Figure 3-1 to connect power cables to corresponding terminals and fix
PE cable to PE terminal.
To avoid unexpected damage, add wire guard to the power cable. Refer Table 3-1 for torque value.
5. After confirming that the cable connection is firm and correct, reinstall the two protective covers at rear of
the cabinet.
Now, the connection of power cables is complete.
Warning
Before cables connection, ensure that all external and internal power switches of the UPS are off, and post necessary warn -
ing signs to prevent inadvertent operation of the switches. Meanwhile, measure the voltages between the UPS terminals
and the voltages between the terminals and the earth.
Warning
1. The earth cables and neutral line must be connected in accordance with local and national codes of practice.
2.
Failure to observe this could result in electric shock or fire risk.
Power distribution mode
Two modes are available for I/O cables: 3-in 3-out, common input configuration (default), 3-in 3-out, split bypass
configuration.
