Design and Installation
2-2-4 Wiring for Noise Resistance
j Wiring Method for FND-X06
Noise resistance will vary greatly depending on the wiring method used. Resistance to noise can be
increased by paying attention to the items described below.
Ground the motor’s frame to the machine ground when the motor is on a movable shaft.
Use a grounding plate for the frame ground for each Unit, as shown in the illustration, and ground to a
single point.
Use ground lines with a minimum thickness of 3.5 mm
are as short as possible.
If no-fuse breakers are installed at the top and the power supply line is wired from the lower duct, use
metal tubes for wiring and make sure that there is adequate distance between the input lines and the
internal wiring. If input and output lines are wired together, noise resistance will decrease.
No-fuse breakers, surge absorbers, and noise filters (NF) should be positioned near the input terminal
block (ground plate), and I/O lines should be isolated and wired using the shortest means possible.
Wire the noise filter as shown at the left in the following illustration. The noise filter should be installed
at the entrance to the control panel whenever possible.
