OPERATION
GROUNDING
Ground the powder coating system properly.
In order to achieve a good powder coating and for safety
reasons (see safety regulations) must the powder coating
system must be properly grounded.
Good grounding of the work piece is a prerequisite for
optimum powder coating. A poorly grounded work piece
causes:
1. Poor wrap-around
2. Uneven coating thickness
3. Back spray onto spray gun and user
4. Dangerous electric charging of the work piece
Requirements for good grounding are:
• Any hangers used to suspend work pieces must
be electrically conductive and connected to earth
ground. The ground of these hangers should be
checked at least weekly. If the resistance regularly
tests above 1 MOhm, the hangers should be cleaned
more frequently than one week.
• The powder hose must have a resistance of less
than 1 MOhm.
Important:
1. Powder residues must be regularly cleaned
from hangers.
2. The grounding cable must be connected to the
control unit.
Earth grounding is on site Form with > 16 mm

copper
conductor to the system ground. The grounding cable
must have a good metallic connection with the coating
enclosure, the recovery unit and the conveyor chain. Any
suspended objects must be connected to the earth ground
of the building.

!
The grounding of all conductive parts (for
example, hooks, chain conveyors, etc.) must be
checked at least weekly.
The Resistance to earth must be <1 MΩ
(Mega Ohm).

All electrical supply lines must be equipped with
grounding conductor and connected. Use only power
cord with ground wire.
