2.2 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.
• Connect the hose for atomizing air to the spraygun and to the control unit.
2.3 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
Warning
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
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.
