(2) Lay the wires in the el. compo. box through the wire inlet on
the side of the el. compo. box.

Do not lay the remote controller wiring or transmission wiring

along with the power supply wiring or other electric wiring in

the same route. Separate the remote controller wiring and

transmission wiring at least 50 mm from the power supply

wiring or other electric wiring, or otherwise malfunctions or

failures may be caused by external electric noise that may

interfere with the remote controller wiring and transmission

wiring.

For the installation and wiring of the remote controller, refer

to the remote controller installation manual provided with the

remote controller.


For power supply wiring, refer to the wiring diagram as well.

Be sure to connect the remote controller wiring and transmis-

sion wiring correctly to the right terminal block.

(3) Follow the instructions below, and lay the wires in the el.

compo. box.

Trim and lay the wiring neatly and attach the el. compo. box 

lid  securely.

An electric shock or fire may result if the el. compo. box lid 

catches any wiring or the wires push up the lid.
(4) Put the el. compo. box lid, and wrap the wire sealing

material (Small (9)) around the wires in order to block the wire

through holes.

After all the wiring connections are done, fill in any gaps in

the through holes with putty or insulation (procured locally) to

prevent small animals and insects from entering the unit from

outside. (If any do get in, they could cause short circuits in

the el. compo. box.)

(5) Mount the provided wire fixing bracket (10) with the wire

fixing screw (11). Fix each wire with the provided clamp (7).

[Precaution s for Power Supply Wiring]

Connect round crimp-style terminals provided with insulation

sleeves to the terminal block for power supply.

Be sure to follow the instructions provided below if the specified 

terminals cannot be used.

Other wise, abnormal  heat may be generated as a result of the 

loo sening of the wires.
