System Requirements
A safe, well designed voltage isolation system should have the following features:
•All components of the isolation system that are charged to high voltage must be contained within an enclosure that prohibits persons from making con- tact with the high voltage components before the system voltage is discharged.
•A bleed resistor to drain off the system voltage when the spray gun is not in use.
•The system should not have any severe arcing occurring when the isolation mechanism opens and closes. Severe arcing will shorten the life of the sys- tem components.
•The system must include a means for automatically discharging the system voltage when anyone opens the isolation enclosure.
CAUTION
The Graco warranty is void if the spray gun is connected to a
