• If the above is not available, make sure to observe the following items.

• 2 wirings of different sizes to the terminal block for power supply is prohibited.

(Abnormal heating may occur if the wirings are not tightened securely.)

• Use the required wirings, connect them securely and fix these wirings 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.

• Conduct wiring so that the earth lead comes out from the notched part of the cup washer. (Otherwise, earth

lead contact will be insufficient and grounding effect may be lost.)

• Do not carry out soldering finish when stranded wirings are used.

9-1 CONNECTION OF TRANSMISSION WIRING, EARTH WIRING AND FOR THE REMOTE

CONTROLLER WIRING

(1) Loosen the fixing screws (2 pcs.) while holding the control box lid, and then remove the control box lid.

(2) Cut off the knockout hole and put the resin bushing (10) (accessory) on the back side (sheet metal).

(3) Connect the transmission wiring through the resin bushing (10) accessory to the terminal block (X2M: 3P)

while matching up the numbers (1 to 3), and then connect the earth wiring to the earth terminal.

After this is done, use the wiring fixture (11) and clamp (4) attached to bind the wiring without applying ten-

sion to the connecting section of the wirings.

(4) Connect the remote controller wiring led from the routing hole to the terminals (P1 and P2) of the terminal

block (X1M: 4P). (There is no polarity.)

After this is done, use the wiring fixture (11) and clamp (4) attached to bind the wiring without applying ten-

sion to the connecting section of the wirings.
