3.4 Grounding the Drive
The drive Safety Ground - PE terminal 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.
For installations within a cabinet, a single safety ground point or ground bus bar
connected directly to building steel should be used. All circuits including the AC input
ground conductor should be grounded independently and directly to this point/bar.
Safety Ground - PE
This is the safety ground for the drive that is required by code. This point must be
connected to adjacent building steel (girder, joist), a floor ground rod or bus bar.
Grounding points must comply with national and local industrial safety regulations
and/or electrical codes.
Shield Termination - SHLD
The SHLD terminal located on the cable entry plate provides a grounding point for the
motor cable shield.
The motor cable shield should be connected to this terminal (drive end) and the
motor frame (motor end). A shield-terminating cable gland may also be used.
When shielded cable is used for control and signal wiring, the shield should be
grounded at the source end only, not at the drive end.
!
ATTENTION: The user is responsible for conforming with all applicable
local, national and international codes. Failure to observe this precaution
could result in damage to, or destruction of, the equipment.
