Observe the notes mentioned below when wiring to the power
supply terminal board.
Do not connect wires of different gauges to the same power
supply terminal. (Looseness in the connection may cause
overheating.)
When connecting wires of the same gauge, connect them
according to the figure.

Use the specified electric wire. Connect the wire securely to
the terminal, Lock the wire down without applying excessive
force to the terminal. (Tightening torque: 1.31N.m 10%).
When attaching the control box lid, make sure not to pinch
any wires.
After all wiring connections are done, fill in any gaps in the
casing wiring holes with putty or insulation material (field
supply) thus to prevent small animals or dirt from entering
the unit from outside and causing short circuits in the control
box.
Do not connect wires of different gauge to the same grounding
terminal. Looseness in the connection may deteriorate the
protection.
Use only specified wires and tightly connect wires to the terminals.
Be careful that wires do not place external stress on the terminals.
Keep wiring in neat order so that they do not obstruct other
equipment such as popping open the service cover. Make sure
the cover closes tight. Incomplete connections could result in
overheating, and in the worst case, electric shock or fire.
