3. 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.
Version
Fixed
Withdrawable
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).
