(single system)
REQUIREMENT
•
Be sure to connect the wires matching the terminal
numbers.
Incorrect connection causes a trouble.
•
Keep a margin (approx. 100 mm) on a wire to hang
down the electrical control box at servicing, etc.
•
The low-voltage circuit is provided for the wired
remote controller.
(Do not connect the high-voltage circuit)

3
Insert the system interconnection wire
(according to the local rule) into the pipe
hole on the wall.
4
Take the system interconnection wire out
of the cable slot on the rear panel so that it
protrudes about 150 mm from the front.
5
Insert the system interconnection wire fully
into the terminal block and secure it tightly
with screws.
Tightening torque: 1.2 N·m (0.12 kgf·m)
Secure the earth wire with the earth screw.
6
