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
supporting surface (see fig. 3).
In any case, it is always advisable to carry out
lifting using the supports (3).

4. Handling
Before carrying out any operations, always make sure that
the operating mechanism spring is 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) fitted 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 circuit-breaker.
