Grounding Requirements
The safety ground-PE must be connected to system ground. Ground impedance must conform to the requirements of national and local industrial safety regulations and/or electrical codes. The integrity of all ground connections should be periodically checked.
Shield Termination—SHLD
The shield terminal provides a grounding point for the motor cable shield. The motor cable shield terminal must be connected to an earth ground by a separate continuous lead. Connect the motor cable shield to this terminal on the drive end and the motor frame (motor end). Use a shield terminating or EMI clamp to connect shield to this terminal.
Radio Frequency Interference (RFI) Filter Grounding
Using an optional RFI filters can result in relatively high ground leakage currents. Therefore, the filter must only be used in installations with grounded AC supply systems and be permanently installed and solidly grounded (bonded) to the building power distribution ground. Be sure that the incoming supply neutral is solidly connected (bonded) to the same building power distribution ground. Grounding must not rely on flexible cables and must exclude any form of plug or socket that would permit inadvertent disconnection. Some local codes can require redundant ground connections. Periodically check the integrity of all connections. See the instructions that are supplied with the filter.
