3. Cutting order
Figure 4 illustrates the cutting order on the front side of the switchgear door when the cutout is widened to the right.
The left side cutting is symmetrical but to the left.
Ensure the needed free space before starting the cutting procedure.
If offcut gatherer is not used, protect the personnel and the switchgear panel from flying offcuts.
It is recommended to use the gatherer. Figure 4 illus-
trates the needed free space when the gatherer is in use.
If there is not enough free space for the gatherer (see
Figure 5 and Figure 6), the cutting head can be used
without the gatherer. However, safety concerns must be
addressed. As the cutoffs may fly from the cutting head,
make sure to pick up all the cutoffs and clean dust after
the work is completed.
