4. Handling
Before carrying out any operations, always make
sure that the operating mechanism springs are
discharged and that the apparatus is in the open
position.
To lift and handle the circuit-breaker, proceed as
follows (fig. 2):
– use a special lifting tool (1) (not supplied) fit-
ted with ropes with safety hooks (2);
– insert the hooks (2) in the supports (3) fixed to
the frame of the circuit-breaker and lift. Put the
hooks (2) into the support holes (3) according
to the type of apparatus (see table);
– on completion of the operation (and in any case
before putting into service) unhook the lifting
tool (1) and dismantle the supports (3) from
the frame.

During handling, take great care not to stress
the insulating parts and the terminals of the cir-
cuit-breaker.
The apparatus must not be handled by
!
putting lifting devices directly under the
apparatus itself. Should it be necessary
to use this technique, put the circuit-
breaker onto a pallet or a sturdy sup-
porting surface (see fig. 3).
In any case, it is always advisable to
carry out lifting using the supports (3).
