Risk of explosion by fixing elements becoming loose
If you use fixing elements made from the wrong material or apply the wrong tightening
torque, this could impair current transfer or cause connecting parts to become loose.
Fastening elements can work loosely, so that the minimum air clearances are no longer
maintained. Sparking formation may occur, in an explosive atmosphere it can lead to an
explosion. This could result in death, serious injury or material damage to the machine or
even in failure, which could in turn lead indirectly to material failure of the system.
● Tighten the screwed connections to the specified tightening torques.
● Observe any specifications regarding the materials from which fixing elements must
be
made
.
● When performing servicing, check the fastenings.
Take the following criteria into account when selecting the connecting cables:
● Rated current
● Rated voltage
● If required, service factor
● System-dependent conditions, such as ambient temperature, routing type, cable cross-
section as defined by required length of cable, etc.
