4. Handling
Before carrying out any operations, always make sure that the operat-
ing 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 special lifting ropes with safety hooks;
– insert the hooks in the supports (1) fixed to the frame of the circuit-
breaker and lift.
– on completion of the operation (and in any case before putting into
service) release the lifting tool and dismantle the supports (1) from
the frame.
During handling, take great care not to stress the insulating parts and
the terminals of the circuit-breaker.
The apparatus must not be handled by putting lifting de-
vices 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).

Storage
When a period of storage is foreseen, our workshops can (on request)
provide suitable packing for the specified storage conditions.
On receipt the apparatus must be carefully unpacked and checked as
described in Checking on receipt (chap. 2).
If immediate installation is not possible, the packing must be replaced,
using the original material supplied.
Insert packets of special hygroscopic substances inside the packing,
with at least one standard packet per piece of apparatus.
Should the original packing not be available and immediate installation is
not possible, store in a covered, well-ventilated, dry, dust-free, non-
corrosive ambient, away from any easily flammable materials and at a
temperature between –5 °C and +40 °C.
In any case, avoid any accidental impacts or positioning which stresses
the structure of the apparatus.
