Connecting the spraygun

Before you start making connections, switch off the high voltage generator. Refer to the
operating instructions of the corresponding control unit for this.
•
Connect the electrical cable to the control unit.
•
Connect the powder hose to the spraygun an to the powder injector.

Grounding

Good grounding of the workpiece is necessary for optimum powder coating. A poorly
grounded workpiece causes:
•
very bad wrap-around
•
uneven coating
•
back-spray onto spraygun and user
•
dangerous electric charging of the workpiece
If the mains cable does not have a separate protective ground terminal, it
is absolutely necessary to connect the control unit to the system ground
by a separate grounding cable via the grounding screw at the back plate of
Warning
the control unit!
Sparks between workpiece and conveyor hooks (hangers) can occur if
hooks or other hanger parts are not completely cleaned! These sparks can
cause heavy radio frequency interference.
