7.16 GROUNDING
For security reasons the Pro Tech M system must be properly grounded.
Wagner recommends the use of a copper cable of at least 16 mm² with su cient mechanical
resistance for connection to the signal ground.
It is important for system's safety and to achieve an optimum coating, that all system
components such as work pieces, conveyors, paint supply, control unit and booth are
perfectly grounded.
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 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).
(Resistance to ground measured at 500 V or 1,000 V).
The footwear worn by the operators must comply with the requirements of
ENISO 20344. The measured insulation resistance must not exceed 100 MΩ (megohms).
No Grounding!
Risk of explosion and risk of electric shock.
Electrostatic control units and the associated spray equipment
may only be connected to mains supplies with a protective
conductor connection (PE conductor)!
DANGER
Heavy powder mist if grounding is insu cient!
Danger of poisoning.
Insu cient paint application quality.
Ground all device components.
Ground the work pieces to be coated.
