WIRING EXAMPLE AND HOW TO SET
THE REMOTE CONTROLLER

HOW TO CONNECT WIRINGS
Methods of wiring power supply, connecting transmission
and remote controller wiring
• Power supply wiring
Remove the electric parts box lid shown in the figure, and
connect to the terminal block (power supply) inside. At this
time, run the wiring from the power supply side of the guide
plate to inside the machine.
• Transmission wiring and remote controller wiring
Connect the terminal block (remote controller / transmission
wiring) so there is no mistake. At this time, run the remote
controller / transmission wiring from the transmission wiring
side of the guide plate to inside the machine.
CAUTION
• Be sure to attach the sealing material or putty (field supplied)
to hole of wiring to prevent the infiltration of water as well as
any insects and other small creatures from outside. Other-
wise a short-circuit may occur inside the electric parts box.
• When clamping the wires, be sure no pressure is applied to
the wire connections by using the included clamping material
to make appropriate clamps. Also, when wiring, make sure
the lid on the electric parts box fits snugly by arranging the
wires neatly and attaching the electric parts box lid firmly.
When attaching the electric parts box lid, make sure no wires
get caught in the edges. Pass wiring through the wiring
through holes to prevent damage to them.
• Make sure the remote controller wiring, the wiring between
the units, and other electrical wiring do not pass through the
same locations outside of the unit, separating them by at
least 50mm, otherwise electrical noise (external static) could
cause mistaken operation or breakage.
CAUTION FOR WIRING
• For connection to the terminal block, use ring type crimp style
terminals with insulation sleeve or insulate the wirings prop-
erly.
• Connect the terminal as shown in Fig. 5.
• Do not carry out soldering finish when stranded wires are
used. (Otherwise, the loosening of wires may result in abnor-
mal heat radiation.)
(Abnormal heating may occur if the wirings are not tightened
securely.)
• Use the required wirings, connect them securely and fix
these wirings securely so that external force may not apply to
the terminals.
• Use a proper screw driver for tightening the terminal screws.
If an improper screw driver is used, it may damage the screw
head and a proper tightening cannot be carried out.
• If a terminal is over tightened, it may be damaged.
Refer to the table shown below for tightening torque of terminals.
Table 5
• Do not carry out soldering finish when stranded wirings are
used.
WARNING
• When wiring, form the wirings orderly so that the control box
lid can be securely fastened. If the control box lid is not in
place, the wirings may come out or be sandwiched by the box
and the lid and cause electric shocks or a fire.
• Use only specified wire and tightly connect wires to termi-
nals. Be careful wires do not place external stress on termi-
nals. Keep wiring in neat order and so as not to obstruct other
equipment such as popping open the electric parts box lid.
Make sure the lid closes tight. Incomplete connections could
result in overheating, and in worse case, electric shock or
fire.
