Installation and Wiring
20
The control cable, power cable and motor cable must be kept apart in order to prevent intercoupling
interference. The three types of cable must be spaced at a sufficiently wide distance, especially when
they are installed parallel to each other and run for a relatively long distance. Whenever the signal cable
has to cross over the power cable, they must be vertical to each other. Refer to the following drawings:
The bigger the length and the cross section of the motor cable, the bigger the capacitance to earth and
the interference caused by intercoupling. Therefore, cables of a specified cross section and of an
appropriately minimized length are recommended.
