5.1.5 EARTHING
Perfect earthing of all system components (work pieces, conveyor, paint supply system,
control unit, spray booth or spraying stand, see illustration) is a prerequisite for optimum
coating effi ciency and safety.
A badly earthed work-piece will result in:
•
Very poor wrap-around
•
Uneven coating thickness
•
Spray-back onto the spray gun, i.e. contamination
The prerequisites for perfect earthing and coating are:
•
Clean work piece suspension
•
Earthing of spray booth, conveyor system and hangers to the building earth in
accordance with the operating instruction or the manufacturer‘s information
•
Earthing of all conductive parts within the working area
•
The earthing resistance of the work piece must not exceed 1 MΩ (Mega Ohm).
•
Connect the control unit to the mains system earth.
