Grounding Your Ultra1500; Grounding Your System To The Subpanel - Allen-Bradley Ultra1500 2092-DA1 User Manual

Grounding Your Ultra1500

All equipment and components of a machine or process system should have a
common earth ground point connected to their chassis. A grounded system
provides a safety ground path for short circuit protection. Grounding your
modules and panels minimize shock hazard to personnel and damage to
equipment caused by short circuits, transient overvoltages, and accidental
connection of energized conductors to the equipment chassis. For CE
grounding requirements, refer to Meeting Emission Requirements in Chapter 1.
To improve the bond between the Ultra1500 and subpanel,
IMPORTANT
construct your subpanel out of zinc plated (paint-free)
steel.
