Wiring of control circuit

(1) Standard control circuit terminal layout
Recommend wire size:
0.3mm 2 to 0.75mm 2
NOTE
 Do not remove the shortening wires across the terminals S1 and SC and the terminals S2 and SC. Removing either
shortening wire disables the drive unit operation.
(2) Wiring method
Wiring
Use a blade terminal and a wire with a sheath stripped off for the control circuit wiring. For a single wire, strip off the sheath of
the wire and apply directly.
Insert the blade terminal or the single wire into a socket of the terminal.
1) Strip off the sheath about the length below. If the length of the sheath peeled is too long, a short circuit may occur
among neighboring wires. If the length is too short, wires might come off.
Wire the stripped wire after twisting it to prevent it from becoming loose. In addition, do not solder it.
2) Crimp the blade terminal.
Insert wires to a blade terminal, and check that the wires come out for about 0 to 0.5 mm from a sleeve.
Check the condition of the blade terminal after crimping. Do not use a blade terminal of which the crimping is
inappropriate, or the face is damaged.
Refer to page 292 for the blade terminals available on the market.
