Step 4: Power Wiring
Grounding Requirements
The drive 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
) provides a grounding point for the motor cable
shield. It must be connected to an earth ground by a separate continuous lead.
The motor cable shield should be connected to this terminal on the drive and the
motor frame. Use a shield terminating or EMI clamp to connect shield to this
terminal.
ATTENTION: National Codes and standards (NEC, VDE, BSI and so forth) and
local codes outline provisions for safely installing electrical equipment.
Installation must comply with specifications regarding wire types, conductor
sizes, branch circuit protection and disconnect devices. Failure to do so may
result in personal injury and/or equipment damage.
