Special operating conditions
If the vacuum circuit-breaker is operated under unfavourable conditions indoors
(heavy and frequent condensation, dusty air, etc.), we recommend cleaning the in-
sulating parts and possibly the outer parts of the circuit-breaker at shorter intervals.
Service life of the vacuum interrupters
If switching operations occur frequently under overload or short circuit, the service
life of the vacuum interrupters may be reached prematurely.
Accessories and spare parts
To ensure that the switchgear operates reliably, spare parts must be replaced only
by trained and certified personnel.
CAUTION
Risk of injury!
The vacuum circuit-breaker should be taken out of the switchgear or switch cab-
inet for servicing.
Separate vacuum circuit-breakers from the control feed voltage or switch it off
and release low-voltage plug or clip connection.
