(5) Check 1PH powered devices, and ensure that no earth lines are used as neutral wires by these
devices.
(6) Do not use shielded cables as inverter power cables and motor cables.

Live device chassis
Phenomenon
After an inverter 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 inverter 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 inverter, and ensure that the jumper at "EMC/J10" on the middle casing of the inverter
is shorted.
