GROUNDING
For safety reasons, the control unit must be properly grounded. The grounding connection
to the energy supply (socket) takes the form of the mains connection cable's protective
conductor, while that to the work piece/system is via the knurled screw on the rear of the
control unit. Both connections are absolutely essential. If installed correctly as described
above, the spray gun is grounded via the gun cable between the control unit and spray gun.
Good grounding of the work piece is also necessary for optimum powder coating.
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
