The insulating parts must be clean if their dielectric strength is to be guaranteed.
Rub insulating parts with a moist cloth.
As a cleaning agent, use only warm water with a mild, liquid household cleaner add-
ed and leave to dry.
For joints and bearing points that cannot be disassembled, only wipe off with a dry,
lint-free cloth.
Under no circumstances may these joints and bearing points be cleaned with clean-
ing agents or water!
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.

Replacing spare parts
To ensure that the device operates reliably, spare parts are permitted to be replaced
only by personnel trained and certified by Siemens.
The vacuum circuit-breaker should be taken out of the switchgear or switch cabinet
for servicing.
