4. Handling

Before proceeding with any operation, always
make sure that the springs of the operating
mechanism spring are discharged and that the
apparatus is in the open position.
When handling the apparatus, take great care to
prevent the insulating parts and the terminals of
the circuit breaker from being stressed.
The apparatus must not be handled by
inserting lifting devices directly under the
apparatus itself. If this technique is
unavoidable, place the circuit breaker on a
pallet or a sturdy supporting surface.
