7.7.5 Live device chassis

After the VFD is started, there is sensible voltage on the chassis, and you may feel an electric
shock when touching the chassis. The chassis, however, is not live (or the voltage is far lower
than the human safety voltage) when the VFD is powered on but not running.
Solution
1. If there is power distribution grounding or ground stud on the site, ground the cabinet
chassis of the drive system through the power ground or stud.
2. If there is no grounding on the site, you need to connect the motor chassis to the ground
terminal PE of the VFD, and ensure that the jumper at "EMC/J10" on the middle casing of
the VFD is shorted.
