DANGER
Use an AC power supply conforming to the power supply specifications of this product.
Use a power supply cable conforming to the power supply capacity. (See the table below.)
Do not connect the power supply cable to the ground terminal.
The ground terminal is connected with the motor frame. Ensure Class D (former Class 3) or higher
grounding condition.
When unsheathing the cable, be careful not to damage the conductors.
Be careful that the cable conductors do not protrude from the terminal block.
CAUTION
For connection of the power supply cable, attach a crimp terminal to the tip of the cable.
The cable inserted into the cable clamp should be a multi-core cable as those recommended below.
If two or more cables are inserted into the clamp, the cable clamp does not conform to the specified
protection rating because of a gap between the cables and the cable clamp.
When connecting the cable, be careful not to drop a screw into the housing.
