EARTHING

Perfect earthing of all conductive parts such as fl oors, walls, roofs, is important for
optimum coating and safety. Barriers, work pieces, transport devices, coating material
container, automatic movement system or construction parts in the spray area must be
connected to the earthing system, with exception of the high-voltage parts during normal
operation.
Parts of the booth must be grounded in accordance with EN 12215.
Discharge of electrostatically charged components in atmospheres
containing solvents!
Explosion hazard from electrostatic sparks or flames
SIHI_0027_GB
Heavy paint mist if earthing is insufficient!
Risk of poisoning
Insufficient paint application quality
SIHI_0003_GB
The imperfect earthing of a work piece will result in:
• Very poor wrap-around.
• Uneven coating thickness.
• Back spraying to 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 suspension on the building side 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 may not exceed 1 M (Mega Ohm).
Note:
Resistance to earth measured at 500 V or 1000 V.
• Connect the control unit to the mains system earth.
