Transmission wire
• 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 specifi ed wire and connect wires to the terminal
tightly. Be careful wires do not place external stress on ter-
minals. Keep wires in neat order so as to not obstruct other
equipment. Make sure that the electric box lid fi ts tightly.
Incomplete connections could result in overheating and, in
worse case, result in electric shock or fi re.
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 specifi ed 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%)

Connect wires of the
same gauge to both side.
2. Tightening torque for the terminal screws.
• Use the correct screwdriver for tightening the terminal
screws. If the blade of screwdriver is too small, the head
of the screw might be damaged, and the screw will not be
properly tightened.
• If the terminal screws are tightened too hard, screws
might be damaged.
• Refer to the table below for the tightening torque of the
terminal screws.

3. Do not connect wires of different gauge to the same ground
terminal. Looseness in the connection may deteriorate pro-
tection.
4. Outside of the unit, keep transmission wire at least 5 in.
away from power supply wire. The equipment may malfunc-
tion if subjected to electrical (external) noise.
5. For remote controller wire, refer to the "INSTALLATION
MANUAL OF REMOTE CONTROLLER" attached to the
remote controller.
