GROUNDING
Perfect grounding of all conductive parts such as fl oors, walls, roofs is important for
optimum coating and safety. Barriers, work pieces, transport devices, coating product
tank, coating product supply or construction parts in the spray area 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 fl ames.
Ground all device components.
Ground the work pieces to be coated.
WARNING
Heavy paint mist if grounding is insuffi
cient!
Danger of poisoning.
Insuffi
cient paint application quality.
Ground all device components.
Ground the work pieces to be coated.
WARNING
A poorly grounded work piece causes:
- very bad wrap around,
- uneven coating,
- back spraying to the spray gun (contamination) and coater.
Prerequisites for perfect grounding and coating are:
- Clean work piece suspension.
- Grounding of spray booth, conveyor system and suspension on the building side in
accordance with the operating manuals or the manufacturer's information.
- Grounding of all conductive parts within the working area.
- The grounding resistance of the work piece may not exceed 1 MΩ (megohm).
(Ground leakage resistance measured at 500 V or 1000 V)
- Connect the control unit to the signal ground.
- Connect all ground cables using a short and direct route.
- Safety shoes and gloves, if used, must be static dissipative.
