To ensure safety, ground the motor using the
inside the terminal
box. On the three phase round shaft motor type, refer to the following
specification.

For wiring, be sure to use cable that meets the following specifications.
Cable: Diameter is Ø6.0 to 12.0 mm (Ø0.236 to 0.472 in.)
Lead Wires: Thickness is AWG24 to 12 (0.2 to 3.5 mm
2
)
Length of strip is 8 mm (0.31 in.)
•
When sealing the terminal cover, ensure that no scraps or particles get
caught between the contact surfaces.
•
The terminal cover screws are specifically designed for mounting the
terminal cover. They are provided with a rubber seal and metal washer
that keep the terminal box splashproof. In order to maintain a tight seal
around the terminal box, use only the provided screws.
Also, this terminal box is constructed to hold a gasket. If this gasket
comes out of the box, please reseal it correctly on the box.
Also refer to the tightening torque table to determine the appropriate
tightening torque to use when fastening the terminal box cover and
cable outlet.

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.
Directions of rotation in the diagram are shown as viewed from the flange
surface of the motor. “CW” indicates clockwise and “CCW”
counterclockwise.
