Grounding Grounding Procedure
The fluid supply is charged with high voltage until
the voltage is discharged. Contact with the charged
components of the voltage isolation system or
spray gun electrode will cause an electric shock.
To avoid an electric shock, do not alter or bypass

the control interface to verify that the system is
discharged:
a. Check that the Ground Rod status indicator
shows the ground symbol
Run Menus, page

on the control interface reads 0 kV. See
Run Menus, page
c. Touch the gun electrode to the grounded rod
(R).
3. If service is required inside the isolation cabinet,
press the Stop button
to change to Off mode.
4. Wait one minute before entering the isolation
cabinet. Use a flat blade screwdriver to open the
cabinet.
5. Use the hand-held grounded rod (R) to dissipate
any static discharge in the cabinet before
touching any components. Pick up the grounded
rod (R) and use it to touch all major components
inside the cabinet. For example, use it to touch
the fluid pump (K), the Merkur pump (L), and the
