Grounding The Powder Coating System; Safety Checks - WAGNER PEM-X1 CG Operating Manual

VERSION 05/2019
Prerequisites for perfect grounding and coating of a work piece are:
– clean suspension of the work piece to be coated,
– the grounding resistance of the work piece must not exceed 1 M
(resistance to ground measured at 500 V or 1000 V).
Sparks between conveyor, conveyor hooks (hangers) and work piece can occur
if electric contact points between conveyor, conveyor hooks (hangers) and work
piece are not sufficiently cleaned and therefore the work pieces are not sufficiently
grounded! These sparks can cause heavy radio frequency interference (EMC).
