9. WIRING EXAMPLE AND HOW TO SET THE REMOTE CONTROLLER
9-1 How to connect wirings
Connection of wiring between units, ground wire and for the remote controller cord (Refer to Fig. 25)
•
Wiring the units and ground wire
Remove the terminal box lid and connect wires of matching number to the terminal block for wiring the units
(3 P) inside. And connect the ground wire to the ground terminal. In doing this, pull the wires inside through
the hole and fix the wires securely with the included clamp (4) (2 points).
•
Remote controller cords (not neccessary for slave unit of simultaneous operation system)
Remove the terminal box lid and pull the wires inside through the hole and connect to the terminal block for
remote controller (6 P). (no polarity) Securely fix the remote controller cord with the included clamp (4) (2
points).
•
After connection, attach sealing pad (13).
•
Be sure to attach it to prevent the infiltration of water from the outside.
[ PRECAUTIONS ]
1.
Use round crimp-style terminals for connecting wires to the power supply terminal block.
If unavailable, observe the following points when wiring.
•
Do not connect wires of different gauge to the same power supply terminal.
(Looseness in the connection may cause overheating.)
•
Use the specified electric wire. Connect the wire securely to the terminal. Lock the wire down without
applying excessive force to the terminal. (Tightening torque: 131N·cm ±10 %)
