Precautions on wiring of power supply

Use a round crimp‐style terminal for connection to the power supply terminal
board. In case it cannot be used due to unavoidable reasons, be sure to observe
the following instructions.
-
Do not connect different gauge wires to the same power supply terminal.
(Loose connections may cause overheating.)
-
When connecting wires of the same gauge, connect them according to the
figure below.

Use the correct screwdriver to tighten the terminal screws. Small screwdrivers can
damage the screw head and prevent appropriate tightening.

Over‐tightening the terminal screws can damage the screws.

Attach a ground fault circuit interrupter and fuse to the power supply line.

In wiring, make certain that prescribed wires are used, carry out complete
connections, and fix the wires so that outside force cannot affect the terminals
Safety device requirment
1. Select the wire diameters ( minimum value) individually for each unit based on the
table 8‐1 and table 8‐2, where the rated current in table 9‐1 means MCA in table
9‐2. In case the MCA exceeds 63A, the wire diameters should be selected
according to the national wiring regulation.
2. Select circuit breaker that having a contact separation in all poles not less than 3
mm providing full disconnection, where MFA is used to select the current circuit
breakers and residual current operation breakers:
