Important: Shield must be terminated in cable clamp to frame.
Ground wire must be connected to GRD terminal.
Important: For use with a 1305 drive with metal conduit entry
panel (frame). Using an RFI filter may result in relatively high
ground leakage currents. Therefore, the filter must be
permanently installed and solidly grounded to the supply
neutral. Grounding must not rely on flexible cables and should
not include any form of plug or socket that would permit
inadvertent disconnection. The integrity of this connection
should be periodically checked. Refer to the instruction manual
for RFI filters for CE compliance and for proper installation
instructions.
