CAUTION

When clamping wiring, use the included clamping material and clamp firmly to prevent outside pressure 
being exerted on the wiring connections.
When doing the wiring, make sure the wiring is neat and does not cause the control box lid to stick up, then 
close the cover firmly.
When attaching the control box lid, make sure you do not pinch any wires.
After all the wiring connections are done, fill in any gaps in the through holes with putty or insulation (pro-
cured locally) to prevent small animals and insects from entering the unit from outside.
(If any do get in, they can cause short circuits in the control box.)
Outside of the unit, separate low-voltage wires (remote controller cords) by a minimum of 50 mm from high-
voltage wires (inter-unit lines, ground lines, and other electrical lines) to avoid routing the two through the 
same locations. Proximity may cause electrical interference, malfunctions, and breakage.

[ Precautions for wiring ]

2 power wires of different diameters cannot be connected to the power terminal block. 
(Slack in the power wiring may cause abnormal heating.)
Use sleeve-insulated round pressure terminals for connections to the power terminal block.
If none are available, connect wires of the same diameter to both sides, as shown in the figure.

Follow the instructions are right if the wiring may get very hot due to slack in the power wiring.

For wiring, use the designated power wire and connect firmly, then secure using the included clamping 
material to prevent outside pressure being exerted on the terminal board.

Use the correct size of screwdriver when tightening the terminal screws. A screwdriver with a small head 
will strip the screw heads and make proper tightening impossible.

Over-tightening the terminal screws may break them.

For the tightening torque of the terminal screws, refer to the table below.

Tightening torque (N·m)

Remote controller wiring terminal block

0.79~0.97

Inter-unit wiring terminal block 

1.18~1.44

Ground terminal

1.44~1.94

Connect same-thickness
wiring to both sides.

GOOD

WRONG

WRONG

It is forbidden to 
connect the two 
wires to one side.
