6 Malfunctions
Faults may result from inadmissible modes of
operation. Such improper operation – even
brief ones – may cause serious damage to the
unit.
In connection with explosion protection, potential
sources of ignition (overheating, electrostatic and
induced charges, mechanical and electric sparks) can
result from these inadmissible modes of operation;
their occurrence can only be prevented by adhering to
the intended use.
