8.3 Cleaning insulating
components
To ensure the specified insulating le-
vel, the insulating components must
be clean.
On principle, general cleanliness of
the circuit-breaker or of its external
parts should be ensured.
Use a dry cleaning cloth for slight
soiling:
Clean by means of a dry, lint-free
cloth. Depending on dirt collected,
replace cloth as often as necessary.
Use cleaning agents for severe
soiling:
Cleaning agent, 1 l can (see Chapter
9.2).
The use of other cleaning agents is
not admissible.
•
Wear protective gloves
•
Use cleaning agent according to
manufacturer's instructions
•
Soak the cloth thoroughly and
wipe the insulating components.
Keep duration of exposure as
short as possible.
•
Expose the cleaned surface to
the air for at least two hours.
When performing cleaning, make
sure that the lubrication in the drive
mechanisms is not removed. If the
drive mechanisms are no longer suf-
ficiently lubricated, new lubrication
must be applied.
8.5 Avoid
condensation
To ensure the specified insulating le-
vel, the circuit-breaker - especially its
insulating components - must not be
exposed to condensation.
Measures to take in case
of condensation:
1. If condensation of the circuit-
breaker is detected, the swit-
ching device must be cleaned
according to section 8.3.
2. Inspect or install heating. It must
provide a sufficient heating per-
formance to prevent condensati-
on on the circuit-breaker.
8.4 Corrosion
protection
Drive mechanisms and covers have a
long-term protection against corrosi-
on. Any damage to the paint, scrat-
ches and other damage must be re-
paired immediately to avoid corrosi-
on. Contact the manufacturer's Ser-
vice Center.
