3 Operation sequences and access inside modules
3.1
Access inside the QMT modules
Before any operation on QMT modules pay particular attention to a warning symbol (Fig. 35).
The panels provided with this symbol (See Fig. 34, 36 with A letter) can be removed only after
checking that they are voltage free.
Removal of the frontal panels (modules without mechanical interlocks) and roof panels etc. are
examples of this situation.
For the switchboards without a warning symbol there are two possibilities:
1. The panel can be removed or opened only after certain operations (For example the door, see
Fig. 34 with B letter).
2. The panel can be removed when the switchboard is energized (For example LV auxiliary box,
see Fig. 34 with C letter.)

WARNING: The indication of voltage presence
indicators alone is not sufficient to prove that the
system is dead.
