Installation and commissioning
17.1
General notes
Installation and commissioning of the vibration monitoring unit may only be performed
by an authorised specialist familiar with the safety regulations governing handling
electrical components. When installing and commissioning EX-certified monitoring units
in potentially explosive atmospheres, the professional must also be familiar with the
relevant safety regulations!
The commissioning will only be carried out with the housing cover correctly screwed on
(tightening torque = 5 Nm)! If EX-certified monitoring is operated in a potentially
explosive atmosphere, there is otherwise an explosion hazard, due to spark formation!
Protect the connection cable and any extension cable from electrical interference and
mechanical damage! Local regulations and instructions must be observed in doing so!

Standard earthing concept
With the standard earthing concept, the sensor cable shield has no connection to the sensor
housing (dashed circle). The sensor housing has the same potential as the machine earth.
