Cable Details
For operations, 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.
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.
Separate power supply lines and signal lines when wiring.
