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.
Models for the gear ratio
and the round shaft type rotate as shown in
the connection diagram.
Models for the gear ratio
rotate in the opposite direction from the
connection diagram.

Contact protection
In order to protect contacts, connecting a CR circuit for surge suppression is
recommended.
It is provided as an accessory (sold separately).
Model:
EPCR1201-2
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.

Changing the cable outlet position
The cable outlet position can be changed to the left or right 90-degree direction, or
the 180-degree direction.
When changing the direction of the cable outlet position, loosen the terminal box
mounting screws, and rotate the terminal box to change the mounting direction.
