CAUTION
• Arrange the wires and x a cover rmly so that the cover does not oat 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 2in. from power supply
wiring. Not following this guideline may result in malfunction due to electrical noise.
9. WIRING EXAMPLE AND HOW TO SET THE REMOTE CONTROLLER
9-1 HOW TO CONNECT WIRINGS
Methods of wiring power supply, connecting transmission and remote controller wiring
• Power supply wiring and ground wire
Remove the control box cover. Connect wires to the power supply terminal block (3P) inside and the
ground wire to the terminal block. Then, fasten a conduit to the conduit mounting plate (13) with a
locknut securely. In doing this, pull the wires inside through the hole and x the wires securely with the
included clamp (4).
Give enough slack to the wires between the clamp (4) and power supply terminal block. (Use Fig. 26 as
a guide and allow at least 3-1/4 in. for removing the sheath.)
• After connection, attach the sealing material. (Refer to Fig. 25). Be sure to attach it to prevent
inltration of water from the outside. Make sure that the slit in the sealing material is positioned
vertically.
After attaching the sealing, screw the conduit mounting plate (13) using the 2 delivered screws (M4)
(14) to the side of the unit where the power supply cables enter the unit. (Refer to Fig. 25).

• Transmission wiring and remote controller wiring
Remove the control box cover and pull the wires inside through the hole and connect to the terminal
block (6P). Securely x the remote controller wiring and the transmission wiring with the included
clamp (4).
Give enough slack to the wires between the clamp (4) and the terminal block for the remote controller.
• After connection, attach sealing material (12).
• Be sure to attach it to prevent the inltration of water as well as any insects and other small creatures
from the outside. Otherwise a short circuit may occur inside the control box.
