Figure 51 - Typical Grounding Example
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
Installed 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.
