To avoid a short circuit in the control box, be sure to apply sealing material or putty (not included) to the
•
wiring hole to prevent the infi ltration of water as well as insects or other small creatures. Otherwise a
short-circuit may occur inside the control box.
CAUTION
When clamping the wirings, be sure no tension is applied to the wire connections by using the included
•
clamp. Also, when wiring, make sure the cover on the control box fi ts snugly by arranging the wirings
neatly and attaching the control box cover fi rmly. When attaching the control box cover, make sure no
wirings get caught in the edges. Pass wiring through holes to prevent damage to them.
Make sure the remote controller wiring and transmission wiring between the units, and other electrical
•
wiring do not pass through the same locations outside the unit, separating them by at least 5”, otherwise
electrical noise (external static) could cause incorrect operation or breakage.
Use only specifi ed 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 popping
open the control box cover. Make sure the cover closes tight. Incomplete connections could result in
overheating, and in worse case, electric shock or fi re.
[ PRECAUTIONS ]
Use round crimp-style terminals for connecting wires to the power supply terminal block.
1.
(Refer to Fig. 23)
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: 0.97ft.lbf ±10 %)

2.
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.
