Shield Termination – SHLD
The shield terminal (see page 157) provides a grounding point for the motor
cable shield. It must be connected to an earth ground by a separate continuous
lead. Connect the motor cable shield to this terminal on the drive (drive end)
and the motor frame (motor end). Use a shield terminating or EMI clamp to
connect shield to this terminal.
RFI Filter Grounding
An optional RFI filter 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. Do not use flexible cables for ground connections, and do not use 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.
