3.2 Risk of destruction due to mechanical overload
Rigid mounting may give rise to constraining forces.
•
Never restrict the freedom of movement of the motor earthing unit. The installation instructions
must be followed.
•
It is essential that the specified clearances and/or angles are observed.
3.3 Risk of destruction due to mechanical shock
Violent shocks, e. g. due to hammer impacts, can lead to the destruction of the unit.
•
Never use force. Assembly is simple when correct procedure is followed.
•
Use suitable puller for disassembly.
3.4 Risk of destruction due to contamination
