Grounding - WAGNER PEA-C4-HiCoat Translation Of The Original Operating Manual

VERSION 05/2019
Procedure:
1. Switch off the high-voltage generation on the control unit.
2. Mount the automatic gun on the mounting bracket and mount both parts, for example,
on the reciprocator's gun support.
Note:
For connecting and fastening the spray gun, use the parts listed in Chapter 12.
The distance of the installed spray guns to each other must be at least 300 mm;
11.81 inches for functional reasons!
3. Connect the automatic gun's electrical cable to the control unit.
4. Connect the powder feed hose to the automatic gun and to the feed system.
5. Connect the atomizing air hose to the automatic gun and to the control unit.
6.6

GROUNDING

For safety reasons, the automatic gun and the work piece must be properly grounded.
The grounding of the automatic gun takes place via the gun mounting.
Good grounding of the work piece is also necessary for optimum powder coating.
A poorly grounded work piece causes:
– dangerous electric charging of the work piece
– very poor wrap-around
– uneven coating
– back spraying to the spray gun, i.e., contamination
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).
