To ensure safety, ground the motor using the
inside the terminal box.
•
Use a cable of the following specifications:
Applicable cable diameter:
∅
12 to 16 mm (
∅
0.47 to 0.63 in.)
Applicable lead wire: AWG18 (0.75 mm

) or more
•
When sealing the terminal cover, ensure that no scraps or particles get
caught between the contact surfaces.
•
This terminal cover is constructed to hold a O-ring. If this gasket comes
out of the cover, please reseal it correctly on the cover.
•
Refer to the tightening torque table to determine the appropriate tightening
torque to use when fastening the terminal cover and cable gland.
Loosening and then tightening the nut again may cause the nipple to
become loose. In this case, securely tighten the nipple again to the
applicable torque specified in the table below [unit: N·m (lb-in)].
Terminal cover (M3)
0.5 to 0.7 N·m (4.4 to 6.1 lb-in)
Cable gland (tightening nut)
2.0 to 2.5 N·m (17.7 to 22 lb-in)
Cable gland (nipple)
10 to 12 N·m (88 to 106 lb-in)
Protective Earth Terminal
1.0 to 1.3 N·m (8.8 to 11.5 lb-in)
Terminal block
0.8 to 1.0 N·m (7.0 to 8.8 lb-in)
Note
•
To make shielding function fully effective, use a cable of
an appropriate diameter.
•
Securely affix the cable exposed outside the motor so
that it does not receive stress.
Wiring diagram
Connect the motor according to the figure. The direction of motor rotation is
as viewed from the side of the motor’s output shaft. The motor rotates in a
clockwise (CW) and counterclockwise (CCW) direction.

Connecting the capacitor (single-phase motor only)
Capacitor terminals are internally electrically connection in twos; A-B and
C-D for easy connection. For easy to install terminals use187 series FASTON
terminals (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.
Simplified connection
Note
Wiring cannot be simplified for vertical drive applications or
three-phase motors.
If the “RUN/STOP” operation of the motor and “RUN/STOP” operation of
the electromagnetic brake are controlled via a single switch (contact),
connect the lead wires as shown in the figure below.
Note that the motor’s magnetic energy affects the electromagnetic brake
windings, resulting in a longer braking time than that of the basic wiring by
approximately 50 ms and thus increased overruns.
