3.3. Special instructions from the product standards
The above mentioned product standards describe the safety requirements for the sta-
tionary equipment for electrostatic coatings. For information and in the interest of safety
the following sections of these standards are especially noted:
Section
5.2.1
(5.3.2)
The distance between the workpiece and the parts under
high-voltage must be so large that in normal operation an
electrical arcing can be prevented.
5.2.3
5.2.4
(5.3.4)
(5.3.5)
[5.2.3]
After switching off the high-voltage all high-voltage carrying
parts must be discharged less than
350 mJ
before these
parts can be reached.
If flammable liquids must be used for cleaning purposes,
there is a valid value of
0.24 mJ.
5.4.5
(5.5.2.3)
[5.3.2]
When using walls, covers, signs and labels made of non-
conducting material there is the risk of propagating brush
discharges. These can occur if low thickness plastics have
contact with large surface grounded conductors (e.g., met-
als). The dielectric strength of the coating must not exceed
4 kV
.
5.5.
[(5.4)]
Description of all requirements for the high-voltage power
supply which the HV generator is a part of.
High-voltage must be switched off and the voltage carrying
parts must be discharged to a safe voltage before interven-
tion on parts under live power.
5.6.
(5.5.2.1)
[5.5]
The electrical equipment that is not a part of the high-voltage
power supply must conform to EN 60204-1.
5.7.
(5.5.2.2)
[5.6.1]
All conductive components of the system, e.g., floors,
transport equipment, etc., with the exception of the normal
operational high-voltage carrying parts, must be grounded.
The bleeder resistance may be max. 1 MΩ.
The sections refer to the corresponding standards:
Without terminals:
EN 50176:2009 and EN 50177: 2009

EN 50223:2015

EN 50348:2010
