ELECTROSTATIC SPRAY CONTROL PANEL
SPRAY CONTROL PANEL
The AutoJet
®
ES250 Electrostatic Spray Control Panel supplies the required voltage to the electrostatic nozzles via a
30,000 VDC (30 kVDC) negative polarity HVPS. At the control panel, the operator can adjust the applied voltage, pump
frequency and start or stop the system modes.
GASKET
The control panel has a gasket installed which creates a seal between the door and the body of the unit. Exercise
caution when opening the unit door as to not damage the gasket. Debris inside the control panel may cause damage to
the system.
4.1 MOUNTING THE PANEL AND DOOR DIAGRAM
MOUNTING
When selecting a control panel mounting location, consider the high voltage cable routing required and your
purchased cable length in relation to the nozzle mounting location. Make sure the control panel is mounted within an
acceptable distance to the nozzle, it is easily accessible to system operators, and the grounding lug is connected to a
grounded GFCI outlet (Figure 4.1).
If mounting the panel to the wall, in a location that is close to your nozzles install wall anchors that are designed to
support at least 25 lbs. (11.34 kg) according to the anchor manufacturer
’
s specifications. The mounting holes are on
6” (152
mm) centers and are made for
1/4” (6
mm) screws with
3/8” (10
mm) diameter screw heads (Figure 4.1
