Verify the power specification
of the motor cooling when
performing wiring.
Refer to page 103.
Avoid frequent ON-OFF.
Repeated inrush currents at
power-on will shorten the
converter life.

CAUTION
• To prevent a malfunction caused by noise, separate the signal cables more than 10cm (3.94 inches)
from the power cables.
• During wiring, do not leave wire offcuts in the inverter.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean. When drilling
mounting holes in an enclosure etc., take care not to allow chips and other foreign matter to enter the
inverter.

REMARKS
When the motor used is not the vector
inverter motor, the pin numbers are different.
The N pin of the PLG designed for vector
inverter motor is case-earthed.
