4E ectiveness of grounding All the system's conductive
elements, such as oors, walls,
ceilings, protective grating,
transport equipment, work
pieces, powder tanks, machines or
construction parts etc. in the spray
area, with the exception of parts
which carry high-voltage during
operation, must be connected to
the grounding system. Parts of
the booth must be grounded in
accordance with EN 12215.
SP
VI/ME/CM
Visual check of ground
connections, perform function
test on grounding switch,
measurement of grounding
resistors.

5 Measures to take if conductive
components are insu ciently
grounded
If su cient grounding of
conductive parts cannot be
ensured, their discharge energy
must not exceed the permissible
value.
SP ME/CM
Measurement of discharge
energy.
weekly
6 Ground leaking resistance from the
workpiece attachment point
The resistance to ground of
every work piece's locating point
must not exceed 1 megohm
(measurement voltage must be
1000 V). The form of construction
of the workpiece mount must
guarantee that the workpieces
remain grounded during coating.
SP ME/CM
Measure resistance to ground
(work piece receiver - ground
potential)
max. 1 megohm @ 1000 V.
