3. Fix power source wiring to terminal bed box by using buffer bushing for tensile
force. (PG connection or the like.) Connect transmission wiring to transmission
terminal bed through the knockout hole of terminal bed box using ordinary
bushing.
4. Connect the power source, Earth, transmission and remote controller wiring.
The dismounting of the terminal bed box is not needed.
[Fig. 9.3.3] (P.5)
E
Use PG bushing to keep the weight of the cable and external force from being
applied to the power supply terminal connector. Use a cable tie to secure the
cable.
Wind the wire around the cable strap once to keep it from being pulled out.

5. After wiring is complete, make sure again that there is no slack on the connec-
tions, and attach the cover onto the terminal bed box in the reverse order of
removal.
Notes:
•
Do not pinch the cables or wires when attaching the terminal bed box
cover. Doing so may cause a risk of disconnection.
•
When accommodating the terminal bed box, make sure that the connec-
tors on the box side are not removed. If removed, it cannot operate nor-
mally.
