Ground leaking resistance
from the work piece attach-
ment point
The resistance to ground of the hold point of ev-
ery work piece may be 1 MΩ at the most (mea-
suring voltage must be 1000 V). The design of
the work piece holder must ensure that the work
pieces remain grounded during coating.

Measure resistance to ground
(work piece receiver - ground po-
tential)
max. 1 MΩ @ 1000 V

Link between technical ven-
tilation equipment and high
voltage, compressed air and
powder feed
The technical ventilation should be interlocked
such that the powder feed and high voltage can-
not be switched on, while the technical ventila-
tion is not working effectively.
SP
FT
Testing whether the system is
stopped by the safety technology
and the powder feed, supply air
and high voltage are switched off
in case of ventilation deactivation.

Checking the electrostatic
manual coating system for
damage
Electrostatic manual coating systems may only
be operated in an undamaged condition. Dam-
aged devices must be decommissioned immedi-
ately and repaired immediately.
SP
FT
Inspect and test (e.g., by measure-
ment) whether all parts carrying
high voltage do not result in dis-
charge which puts people at risk.
