6-2 Wiring Connection Method
(1) Remove 2 mounting screws of the electrical component box to open it.
(2) Perform installation of remote controller and power supply wiring.
Fix the power supply wiring, earth wires, and transmission wiring
(signal line and remote controller) securely in place with the clamp
③ (accessory) as shown in the figure on the right.
(3) When closing the electrical component box, make sure that the cover
catches no wire, and then fix it securely with 2 mounting screws.
Form the wiring orderly so that the electrical component box can be securely attached.
Electric wires that got pinched or the electrical component box that does not sit properly may
cause electric shock or fire.
<Connecting power supply wiring and earth wires>
Pass the power supply wiring and the earth wires through the wiring through-hole
(upper) into the electrical component box, as shown in the figure on the right.
Connect the power supply wiring to the terminal block (X1M).
Connect the earth wires to the earth
terminals.
Take out the earth wire from the notch of the
cup washer and lay the wire carefully so that
the washer will not catch other wires.
Otherwise, the earth wire may not contact sufficiently, and the earthing
effect of the wire may be lost.
Fix the power supply wiring and earth wires securely to the resin clamps
(1 locations) with the clamp ③ (accessory). (Enlarged view – 1)
<Connecting remote controller wiring and transmission wiring (low voltage)>
See the "Remote Controller Installation Manual" that comes with the remote
controller for details on installation of and wiring for the remote controller.
Pass the remote controller wiring and the transmission wiring through the
wiring through-hole (lower) into the electrical component box, as shown in
the figure on the right.
Connect the remote controller wiring to [P1/P2] and the transmission wiring
to [F1 / F2] of the terminal block (X1M), respectively. (No polarity: Enlarged view – 2)
Fix the remote control wiring and transmission wiring securely to the resin
(1 location) and push mounts (2 locations) with the clamp ③
clamp
(accessory). (Enlarged view – 3, Enlarged view – 4)
<CAUTION>
Make sure that all wiring is securely connected to the respective
terminal, using the specified wires, and the sheath section is fixed with a
provided clamp, ensuring that external forces do not act on the terminal.
Use the correct screwdriver for tightening the terminal screws.
If the screwdriver's blade 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, the screws might be
damaged.
Refer to the table below for the tightening torque of the terminal screws.
Terminal block (X1M, X2M, X3M) (M3.5)
When installing the unit upside down, fix the external wiring (power
supply wiring, earth wires, remote control wiring, and transmission
wiring) to the push mounts (1 location each) with the clamp ③
(accessory) as shown in the figure on the right. (Enlarged view – 4)
Condensation water may enter the electrical component box and cause
a failure.
