Grounding - WAGNER SPRINT XE Translation Of The Original Operating Manual

Operating manual Manual Powder System SPRINT XE
6 Assembly and Commissioning
6. Connect the dosing air hose (blue).
7. Connect the feed air hose (red).
8. Connect hose (black) for the fluid air to the throttle and to the tank (A). Bundle the
three hoses with Velcro cable binders.
9. Connect the powder feed hose.
10. Plug in the gun connection cable on the control unit.
11. Connect the hose (transparent) for the atomizing or Tribo air. Bundle the two hoses and
the gun cable with Velcro cable binders.
12. Connect exhaust air hose to the connection on the powder tank. The other end of the
exhaust air hose must be routed to the extraction unit of the powder spray booth!
13. Connect the compressed air hose (12.5 x 18.5 mm, order no. 9981951) to the
compressed air connection (G1/4") on the manual system.
14. Connect the trolley grounding cable to the control unit. Connect the control unit's
grounding cable with the signal ground!
15. Attach the cover to the mains output terminal from the control unit.
16. Plug in the control unit mains cable.
17. Connect mains cable to the power supply.
6.6 GROUNDING
For security reasons the manual system must be properly grounded. Normally this is done
via the mains cable.
Good grounding of the work piece is also necessary for optimum powder coating.
It is important to keep the ground cables as short as possible. Ground cables of an excessive
length must be shortened. Ground cables of an excessive length must never be wound up
on a roller.
A poorly grounded work piece causes:
– dangerous electric charging of the work piece
– very bad wrap-around
– uneven coating
– back spraying to the spray gun, i.e., contamination
Prerequisites for perfect grounding and coating of a work piece are:
– Clean suspension of the work piece to be coated.
– That a grounding resistance of the work piece of 1 MΩ is not exceeded
(resistance to ground measured at 500 V or 1000 V).
Sparks between conveyor, conveyor hooks (hangers) and work piece can occur if
electric contact points between conveyor, conveyor hooks (hangers) and work piece
are not sufficiently cleaned and therefore the work pieces are not sufficiently
grounded! These sparks can cause heavy radio frequency interference (EMC).
