Precautions for configuring the machinery compliant with the EMC Directives
using the A1SD75P -S3 (abbreviated as A1SD75 hereafter), AD75P -S3
(abbreviated as AD75 hereafter) are described below.
1) When wiring with a 2 m (6.56 ft.) or less cable
• Ground the shield of the external device connection cable with a cable
clamp. (Ground the shield at the closest location to the A1SD75/AD75
external wiring connecter.)
• Wire external device connection cables to drive modules and external
devices by the shortest distance.
• 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 of the external device connection cable with a cable
clamp. (Ground the shield at the closest location to the A1SD75/AD75
external wiring connecter.)
• Wire external device connection cables to drive modules and external
devices by the shortest distance.
• Install a ferrite core.
