• Power supply wire
Holding the control box lid, loosen the 2 securing screws,
remove the control box lid, match up the phases on the power
supply terminal block inside (2P), and make the connections.
After this is done, use the attached clamp (4) to bind wire
between units to the anchor point.
(Refer to Fig. 28)
• Remote controller wire and transmission wire
Holding the control box lid, loosen the 2 securing screws,
remove the control box lid.
Thread the remote controller wire and transmission wire
through the insulating tube (11) and secure with the clamp
(4), and cut off the insulating tube (11) to suitable length. The
insulating tube (11) can let the wire pass to 2. If there are 3 or
more wires, use another insulating tube (11). Pull the wires
inside through resin bush and connect the wires to the trans-
mission terminal block (6P) inside the control box. After con-
necting, use the clamp (4) to bind the remote controller wire
together with the transmission wire to the anchor.
(Refer to
Fig. 27, 28, 29)
• In the insulating tube (11), it can let the remote controller wire
and transmission wire pass to 2.
WARNING
• Never connect power supply wiring to the terminal block for
remote controller wiring as this could damage the entire system.
• Use only specified wire and connect wires to the terminal
tightly. Be careful wires do not place external stress on termi-
nals. Keep wires in neat order so as to not obstruct other
equipment. Make sure that the electric box lid fits tightly.
Incomplete connections could result in overheating and, in
worse case, result in electric shock or fire.
CAUTION
• To avoid a short circuit in the electric parts box, be sure to
apply sealing material or putty (not included) to the wiring
hole to prevent the infiltration of water as well as insects or
other small creatures.
NOTE
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 : 0.97 ft.lbf ±10%)
