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)
may result from these inadmissible modes of
operation; their occurrence can only be prevented by
adhering to the intended use.
