• Transmission wiring and remote controller wiring
Unscrew and remove the service cover.
Connect the remote controller wiring and the transmission wiring to the terminal block (6P).
When doing this, tie the remote controller wiring and the transmission wiring using the included clamp (small)
(5) and then firmly secure using the included clamp (small) (5) according to the figure. (Refer to Fig. 23)
• Be sure to attach it to prevent the infiltration of water as well as any insects and other small creatures from
the outside. Otherwise a short-circuit may occur inside the control box.
CAUTION FOR WIRING
• For connection to the terminal block, use ring type crimp style terminals with insulation sleeve or insulate
the wirings properly.
• Connect the terminal as shown in Fig. 21.
• Do not carry out soldering finish when stranded wires are used. (Otherwise, the loosening of wires may
result in abnormal heat radiation.)
(Abnormal heating may occur if the wirings are not tightened securely.)
• Use the required wirings, connect them securely and fix these wirings securely so that external force may
not apply to the terminals.
• Use a proper screw driver for tightening the terminal screws.
If an improper screw driver is used, it may damage the screw head and a proper tightening cannot be car-
ried out.
• If a terminal is over tightened, it may be damaged.
Refer to the table shown below for tightening torque of terminals.

• Do not carry out soldering finish when stranded wirings are used.
WARNING
• When wiring, form the wirings orderly so that the control box lid can be securely fastened. If the control box
lid is not in place, the wirings may come out or be sandwiched by the box and the lid and cause electric
shocks or a fire.
