Connection
•
Insulate all the wire connections, such as the connection between the motor
and the capacitor connection.
•
For safety’s sake, install a breaker or fuse in the power line.

Connecting Protective Earth Terminal
Be sure to ground the motor using the Protective Earth Terminal on the motor.
Use a crimp terminal described below for grounding.
Applicable crimp terminal:
Insulated round crimp terminal
Terminal screw size: M4
Tightening torque:
1.0 to 1.3 N·m (8.8 to 11.5 lb-in)
Applicable minimum lead wire size:
AWG18 (0.75mm
2
) or thicker
Ø4.1 (0.16) or more
[ Unit: mm (in.) ]
4.8 (0.19) or less
9.5 (0.37) or less
Note
Be sure to use the screw for grounding attached on the product.
Wiring diagram
The rotation direction of the combination type varies depending on the gear
ratio of the gearhead.
Check the motor model name and the gear ratio before connecting.
The connection diagram is an example of the lead wire type.
When connecting as the connection diagram the motor rotates in
the direction as shown below.

Capacitor connection
When crimp terminals are used, use the FASTON
terminals 187 Series (TE Connectivity).
Use the supplied capacitor cap to insulate the
capacitor terminal connection.

Note
For lead wire connection, use one lead wire for each individual
terminal.
Connection method to a terminal block
Remove the terminal box cover for the terminal box type, and connect a cable.
Cables for connection are available as accessories (sold separately).
•
If the O-ring that has set in the matching surface of the terminal box cover
falls off, install it securely in the groove portion of the terminal box cover.
•
After connecting the cable, securely tighten with the tightening torque in the
table below.
Note
•
To make shielding function fully effective, use a cable of an
appropriate diameter and observe the specified tightening torque
of screws.
•
Secure the cable drawn from the motor terminal box so that it does
not receive stress.
