Safety Ground - PE
This is the safety ground for the AFE that is required by code. This point must be
connected to adjacent building steel (girder or joist), a floor ground rod or bus
bar (see above). Grounding points must comply with national and local industrial
safety regulations and/or electrical codes.
Shield Termination - SHLD
The Shield terminal ( Figure 30 or Figure 31 ) provides a grounding point for the
AFE cable shield. It must be connected to an earth ground by a separate
continuous lead. The drive cable shield must be connected to this terminal on
the AFE end and the drive frame on the drive end. Use a shield terminating or
EMI clamp to connect the shield to this terminal.
