8EMC AND LOW VOLTAGE DIRECTIVE

(b)Positioning modules

MELSEC-Q

Precautions to be followed when the machinery conforming to the EMC Directive is configured using the A1SD75P1-S3/A1SD75P2-S3/A1SD75P3- S3 (hereafter referred to as the A1SD75) are described below.

1)When wiring with a 2 m (6.56 ft.) or less cable

•Ground the shield section of the external wiring cable with the cable clamp. (Ground the shield at the closest location to the A1SD75 external wiring connector.)

•Wire the external wiring cable to the drive unit and external device with the shortest practicable length of cable.

•Install the drive unit in the same panel.

2)When wiring with cable that exceeds 2 m (6.56 ft.), but is 10 m (32.79 ft.) or less

•Ground the shield section of the external wiring cable with the cable clamp. (Ground the shield at the closest location to the A1SD75 external wiring connector.)

•Install a ferrite core.

•Wire the external wiring cable to the drive unit and external device with

the shortest practicable length of cable.
