Observe the notes mentioned below when wiring to the terminal block for wiring the units.
CAUTION
•
When clamping wiring, use the included clamping material to prevent outside pressure being exerted on
the wiring connections and clamp firmly. When doing the wiring, make sure the wiring is neat and does not
cause the control box lid to stick up, then close the cover firmly.
•
When attaching the control box lid, make sure you do not pinch any wires.
•
After all the wiring connections are done, fill in any gaps in the through holes with putty or insulation (pro-
cured locally) to prevent small animals and insects from entering the unit from outside. (If any do get in, they
could cause short circuits in the control box.)
•
Outside the machine, separate the weak wiring (remote controller cord) and strong wiring (interunit,
ground, and other power wiring) at least 50 mm so that they do not pass through the same place together.
Proximity may cause electrical interference, malfunctions, and breakage.
•
Do not connect wires of different gauge to the same power supply terminal. (Looseness in the connection
may cause overheating.)
(Refer to Fig. 20)
•
Observe the notes when wiring to the terminal block for wiring the units.
(Use a round crimp-style terminal with insulation sleeve for connection to the terminal block for wiring the
units. In case it cannot be used due to unavoidable reasons, connect wires of the same gauge to the both
side as shown in Fig. 20.)
Follow the instructions below if the wiring gets very hot due to slack in the power wiring.
•
In wiring, make certain that prescribed wires are used, carry out complete connections, and fix the wires so
that outside forces are not applied to the terminals.
•
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 screw are tightened too hard, screws might be damaged.
•
Refer to the table below for the tightening torque of the terminal screws.
Tightening torque (N·m)
Terminal block for remote controller
0.79 to 0.97
Terminal block for wiring the units
1.18 to 1.44
Ground terminal
1.44 to 1.94
Connect wires of the
same gauge to both
side. (GOOD)
Do not connect wires
of the same gauge to
one side.(WRONG)
Do not connect
wires of different
gauges.(WRONG)
