Procedures:
1. There are two protective covers at the rear of the cabinet. The user can use the cabling hole on No.1
protective cover for routing the cables according to actual needs.
NOTE: The guard ring or flange needs to be installed around the cabling hole so as not to cut the
cables.
2. Dismantle the No.2 protective cover.
3. If 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) into the cabinet through corresponding
cabling hole. Follow Figure 3-1 to connect power cables to corresponding terminals and fix PE cable to
PE terminal. If common input configuration, just lead the main input cables (mA, mB, mC, N, PE), and
output cables (oA, oB, oC, N, PE) into the cabinet through corresponding cabling hole.
4. If the user adopts external battery, just lead the battery cables into the cabinet through the reserved
cabling hole at top of the routing area. Follow Figure 3-1 to connect power cables to corresponding
terminals and fix PE cable to PE terminal.
Add wire guard to the power cable to avoid unexpected damage. Refer to Table 3-1 for torque value.
5. After confirming the cables connection is firm and correct, then reinstall the two protective covers at
rear of the cabinet.
Now, the connection of power cables is complete.
