CAUTION
Be sure to attach the sealing material and putty (field supplied) to hole of wiring to prevent the infiltration
of water as well as any insects and other small creatures from outside. Otherwise a short-circuit may
occur inside the electric parts box.
When clamping the wirings, be sure no pressure is applied to the wire connections by using the included
clamp to make appropriate clamps. Also, when wiring, make sure the lid on the control box fits snugly by
arranging the wirings neatly and attaching the service lid firmly. When attaching the service lid, make sure
no wirings get caught in the edges. Pass wiring through the wiring through holes to prevent damage to
them.
Make sure the remote controller wiring, and transmission wire the wiring between the units, and other elec-
trical wiring do not pass through the same locations outside the machine, separating them by at least
50mm, otherwise electrical noise (external static) could cause mistaken operation or breakage.
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 popping open the
service cover. Make sure the cover closes tight. Incomplete connections could result in overheating, and in
worse case, electric shock or fire.
[ PRECAUTIONS ]
1.
Use round crimp-style terminals for connecting wires to the power supply terminal board.
(Refer to Fig. 21)
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.)
•
When connecting wires of the same gauge, connect them according to Fig. 22.
•
Use the specified electric wire. Connect the wire securely to the terminal. Lock the wire down without
applying excessive force to the terminal. (Tightening torque: 131N·cm ±10 %)
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.
Keep transmission wiring at least 50mm away from power supply wiring. The equipment may malfunction
if subjected to electrical (external) noise.
5.
For remote controller wiring, refer to the “INSTALLATION MANUAL OF REMOTE CONTROLLER”
attached to the remote controller.
6. Never connect power supply wiring to the terminal block for remote controller. A mistake of the
sort could damage the entire system.
