Grounding of the units: Attach a ground wire from one of the threaded studs (A) at the bottom of the housing, to the mounting plate (B). The ground resistance between. How should we protect ourselves from the safety issue? For example, for High And Low Voltage Distribution Cabinets, the distribution box needs to be grounded regardless of size. The grounding "bus" (grounding bus, PE bus) in the box is directly. Grounding is a mechanism to protect distribution equipment and people under normal operating conditions, abnormal operational (overcurrent and overvoltage) responses, and hazardous conditions such as shocks. The drive system in this manual consists of the supply transformer, input power cable of the drive, the variable speed drive (frequency converter), motor cable and motor. While both systems aim to prevent electric shocks and safeguard equipment, their working principles, implementation, and safety. Improper grounding or earthing of “Distributed Control Systems (DCS)” or “Power Electronic Systems (PES)” can result in either mal-operation of the system / controller or failure of electronic control cards or sometimes even the embedded control software getting erased.
