3.6 Grounding
Make sure grounding is done according to national and local electrical
codes. Failure to do so may impair the protection provided by the
equipment.
3.6.1 Signal cable shield grounding
Make sure the instrument cable shield is:
• Trimmed close and insulated from touching the housing.
• Continuously connected throughout the segment.
• Connected to a good earth ground at the power supply end.

3.6.2 Grounding the housing
The most effective grounding method for the metal housing is a direct
connection to earth ground with minimal impedance. Housings with NPT
conduit entries do not have an earth ground point and must use the fork
earth.
