4. Handling

Before proceeding with any operation, always make
sure that the spring of the operating mechanism is
discharged and that the apparatus is in the open
position.
Proceed as follows to lift and handle the circuit-
breaker (fig. 2):
• use suitable lifting equipment (1) (not supplied)
with ropes and safety hooks (2);
• insert the hooks (2) into the supports (3) fixed to
the frame of the circuit-breaker and lift. Insert
hooks (2) into holes in support (3), depending on
the type of apparatus (see table);
• once the operation has terminated (and in any
case before putting into service), release the
lifting equipment (1) and remove the supports (3)
from the frame.
When handling the apparatus, take great care to
prevent the insulating parts and terminals of the
circuit-breaker from being stressed.

Do not handle the apparatus by
inserting lifting devices directly under
it. If this technique is unavoidable, place
the circuit-breaker on a pallet or a
sturdy supporting surface (see fig. 3).
In any case, it is always advisable to lift
the apparatus by means of the supports
(3).
