Multiple double-shielded twisted-pair cables
Multiple shielded twisted-pair cables
For low-voltage digital signals, double-shielded cables are recommended, but shielded or
unshielded twisted pairs (as shown in figure b) also can be used. For frequency signals,
however, only shielded cables can be used.
Relay cables need to be those with metal braided shield layers.
Keypads need to be connected by using network cables. In complicated electromagnetic
environments, shielded network cables are recommended.
Note:
Analog signals and digital signals cannot use the same cables, and their cables must be
arranged separately.
Do not perform any voltage endurance or insulation resistance tests, such as high-voltage
insulation tests or using a megameter to measure the insulation resistance, on the VFD or its
components. Insulation and voltage endurance tests have been performed between the main
circuit and chassis of each VFD before delivery. In addition, voltage limiting circuits that can
automatically cut off the test voltage are configured inside the VFDs.
Note:
Check the insulation conditions of the input power cable of a VFD according to the local
regulations before connecting it.
