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.
Dielectric withstand tests have been performed between the main circuit and housing of each VFD
before delivery. In addition, the VFD has the internal voltage limiting circuit, which can automatically
cut off the test voltage. Do not perform any voltage withstand 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.
Note: Before connecting the input power cable of the VFD, check the insulation conditions of the
cable according to local regulations.
