Power supply wire, Ground wire (Refer to Fig. 17)
Connect the wire to L and N on the power supply terminal block (X1M). Also, connect the ground wire to the
ground terminal. Take the power supply wire and the ground wire into the unit through the wiring through hole
<1>, and firmly secure them together using the clamp (Accessory 10)).
Transmission wire, Remote controller wire (Refer to Fig. 17)
Connect the transmission wire to F1 and F2 on the transmission terminal block (X2M). Connect the remote
controller wire to P1 and P2 on the transmission terminal block (X2M). Take them into the unit through the wiring
through hole <2>, and firmly secure the wires using the clamp (Accessory 10)).
CAUTION
Wire the electric parts box so that the wiring is at least 10 mm above the bottom of the electric parts box.
Be sure to attach the sealing material or putty (field supplied) to the wiring through holes to prevent the infiltration
of water as well as any insects and other small creatures from outside. Other-wise a short-circuit may occur inside
the electric parts box.
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 electric parts box fits snugly by
arranging the wires neatly and attaching the electric parts box lid firmly. When attaching the electric parts 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 50mm, 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.
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.
