7-5 GIST OF FIELD LINE CONNECTION
•
Remove the side cover of the electric parts box shown in the figure below and connect each wire.
NOTE
•
Keep transmission wiring a minimum of 5’’ from other electric wires so as to avoid the effects of external
noise. (Bundle transmission wiring separate of other wires, with the included tie-wrap.)
•
Do not connect power wiring to the transmission wiring terminal.
Doing so could damage the entire system.
•
Clamp power wiring and the grounding wire together with the included clamp.
•
When clamping wiring, use the included clamp 2) to prevent outside pres-
sure being exerted on the wiring connections and clamp firmly. When doing
the wiring, make sure the wiring is neat and does not cause the electric
parts box lid to stick up, then close the cover firmly. When attaching the elec-
tric parts box lid, make sure you do not pinch any wires. To prevent the wires
from damaging, be sure to pass all wires through the wiring guide.
•
After wiring work is complete, block all gaps in the holes for passing out wir-
ing using sealing material (locally procured).
(This is to prevent insects from entering the machine.)
PRECAUTIONS
1.
Use ring-type crimp-style terminals for connecting wires
to the power supply terminal board. 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 the right figure.
•
Use the specified electric wire. Connect the wire
securely to the terminal. Lock the wire down without
applying excessive force to the terminal.
•
Use an appropriate screwdriver for tightening the termi-
nal screws. A screwdriver with a small head will strip the head and make proper tightening impossible.
•
Over-tightening the terminal screws may break them.
•
See the following table for the tightening torque of the terminal screws.
Tightening torque (ft-lbf)
Remote controller/branch wiring terminal block (4P)
0.58~0.72
Power supply terminal block (2P)
0.87~1.06
Grounding wire
1.12~1.37
