CAUTION
•
Arrange the wires and fix a lid firmly so that the lid does not float during wiring work.
•
Do not clamp remote controller wiring and transmission wiring together with power supply wiring. Doing so
may cause malfunction.
•
Remote controller wiring and transmission wiring should be located at least 50 mm from power supply wir-
ing. Not following this guideline may result in malfunction due to electrical noise.
8. HOW TO CONNECT WIRINGS AND WIRING EXAMPLE
8-1 HOW TO CONNECT WIRINGS
Methods of wiring power supply, units and connecting remote controller wiring
•
Power supply wiring and ground wire
Unscrew and remove the service lid.
Connect the power supply wiring and ground wiring to the power supply terminal block (3P).
When doing this, tie the power supply wiring and the ground wiring using the included clamp (small) (5) and
then firmly secure using the included clamp (small) (5) according to the figure.
(Refer to Fig. 21)
•
Transmission wiring and remote controller wiring
Unscrew and remove the service lid.
Connect the remote controller wiring and the transmission wiring to the terminal block (6P).
When doing this, tie the remote controller wiring and the transmission wiring using the included clamp (small)
(5) and then firmly secure using the included clamp (small) (5) according to the figure.
(Refer to Fig. 21)
•
Be sure to attach it to prevent the infiltration of water as well as any insects and other small creatures from
the outside. Otherwise a short-circuit may occur inside the control box.
[PRECAUTIONS]
Observe the notes mentioned below when wiring to the power supply terminal block and terminal block for
remote controller.
Tightening torque for the terminal blocks
•
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.
When none are available, follow the instructions below.
Do not connect wires of different gauge to the same grounding terminal.
Looseness in the connection may deteriorate protection.
