If a control cable and power cable must cross each other, ensure that the angle between them is 90°.

The cable trays must be connected properly and well grounded. Aluminum trays can implement local
equipotential.
For inputs of such as relay signals and other non-differential signals, non-twisted pair cables can be used,
and the wiring should minimize the loop area and a pair of signal lines should be routed as close as possible.
When laying multiple types of cables, the cables should always be routed along the alignment grooves or
metal pipes in equipotential connection, with different types of cables separated as much as possible. You
can better improve electromagnetic compatibility by using metal spacers to isolate different types of cables
in the same metal groove or metal pipe.
