Handling - ABB VD4 Installation And Service Instructions Manual

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.

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).
