D.4.2 Control cables
All analog control cables and cables used for frequency input must be shielded cables. Analog signal
cables need to be double-shielded twisted-pair cables (as shown in figure a). Use one separate
shielded twisted pair for each signal. Do not use the same ground wire for different analog signals.

Figure D-2 Configuration of the power cable
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.
