Remote controller and transmission wiring
Pull the wires into the unit through the wiring through hole
and connect to the terminal block (6P).
Be sure to put the part of the sheathed vinyl into the control
box.
Precautions when laying power supply wiring
•
Wiring of different thicknesses cannot be connected to the
power supply wiring terminal block. (Slack in the power sup-
ply wiring may cause abnormal heat.)
•
Use sleeve-insulated round crimp-style terminals for connec-
tions to the power supply wiring terminal block. When none
are available, connect wires of the same diameter to both
sides, as shown in the figure.
Follow the instructions are below if the wiring may get very
hot due to slack in the power supply wiring.
•
For wiring, use the designated power supply wiring and con-
nect firmly, then secure to prevent outside pressure being
exerted on the terminal board.
•
Use the correct screwdriver for tightening the terminal
screws. If the blade of screwdriver is too small, the head of
the screw might be damaged, and the screw will not be prop-
erly tightened.
•
If the terminal screws are tightened too hard, screws might
be damaged.
•
Refer to the table below for the tightening torque of the termi-
nal screws.
