PUTTING MAGIC TBR INTO OPERATION

2.3 Earthing of the system
For EMC reasons an earthing via the earthing screw on the back side of the unit
must be carried out in either case.
Earthing
A lacking earthing can cause functional deficiencies within the unit. Because of the
‘pending’ potential, unlike the protective earth conductor potential, slight electric
shocks can occur by touching the rack. These are absolutely not dangerous;
however, they can be avoided totally by earthing.
