Fasten electrode ring
Prerequisite:
- The flange assembly is installed on the atomizer slot or the elbow
and fully connected and grounded.
- High voltage connection is secured to the flange assembly.
- Cable for potential equalization is fastened on the flange assembly.
The electrode ring is screwed to the flange assembly.
The electrode ring is provided in individual parts and must be
assembled first.
Before assembling the parts of the electrode ring (ring and fingers),
they must be stored at a temperature between 20 °C and 26 °C for at
least 24 hours.
• Protective caps on the electrode ring must be removed.

Risk of damage to property and production disruption
Penetration of moisture can cause electro-chemical corrosion of
insulating components and thus lead to malfunctions during the high
voltage operations.
Before assembly of the electrode ring to the flange assembly, the
sealing surface and groove on the backside of the electrode ring must
be filled with petroleum jelly. The petroleum jelly seals and insulates
the gap between flange assembly and electrode ring.
