Grounding - Graco ProControl 1KE Instructions - Parts Manual

Installation

Grounding

The equipment must be grounded to reduce the
risk of static sparking and electric shock. Electric
or static sparking can cause fumes to ignite or
explode. Improper grounding can cause electric
shock. Grounding provides an escape wire for the
electric current.
NOTE: The ProControl 1KE does not provide 500
VAC isolation through the coupling nuts on the
enclosure. The associated apparatus and the field
apparatus cable shields must not be connected to
the ProControl 1KE coupling nuts.

IS system, the ProControl 1KE also is grounded
by connection to the grounded power supply.

308778 (G3000) or manual 313599 (Coriolis) to
ground the flow meter and check its electrical
grounding continuity.
