•
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 or 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.
•
Separate power supply lines and signal lines when wiring.
•
The noise filter must be installed as close as possible to the entrance of the control panel. Wire as
shown at the left in the following illustration.
•
Use twisted-pair cables for the power supply cables, or bind the cables.
