 When clamping the wires, be sure no pressure is applied to the wire connections by using the included clamping
material to make appropriate clamps. Also, when wiring, make sure the lid on the electrical components box fits
snugly by arranging the wires neatly and attaching the electrical components box lid firmly. When attaching the
electrical components box lid, make sure no wires get caught in the edges. Pass wire through the wiring through
holes to prevent damage to them.
 Make sure the remote controller wire, the transmission wire and power supply wire, ground wire do not pass through
the same locations outside of the unit, separating them by at least 2in., otherwise electrical noise (external static)
could cause mistaken operation or breakage.
PRECAUTIONS
1. Use round crimp-style terminals for connecting wires to the power supply terminal block.
If unavailable, observe the following points when wiring.w
 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.
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
protection.
4. Outside of the unit, keep transmission wire and remote controller wire at least 2in. away from power supply wire and
ground wire. The unit may malfunction if subjected to electrical noise (external static).
5. For remote controller wiring, refer to the "INSTALLATION MANUAL OF REMOTE CONTROLLER" attached to the
remote controller.
6. Never connect power supply wire to the transmission terminal block (X2M). A mistake of the sort could damage the
entire system.
7. Use only specified wire and tightly connect wires to terminals. Be careful wires do not place external stress on
terminals. Keep wiring in neat order and so as not to obstruct other equipment such as the electrical components box
lid. Make sure the lid closes tight. Incomplete connections could result in overheating, and in worse case, electric
shock or fire.
