General notes

Assembly and disassembly work on and with the vibration monitoring unit may only be perfor-
med by an authorised specialist familiar with the safety regulations governing handling electrical
components.

Fixing the vibration monitoring unit to the mounting surface

13.2.1 Prerequisites
• Mounting surface is clean and flat; i.e. free of paint, rust, etc.
• Measuring head area of the vibration monitoring unit must lie flat on the mounting surface.
13.2.2 Tool
• Hex key, width A/F 24
13.2.3 Work steps and instructions
• Screw vibration monitoring unit into the threaded hole of the mounting surface in a friction-lo-
cked manner using a hex key. The tightening torque should be 8 Nm.
• The tightening torque of the M12 union nut of the plug connection must not exceed 0.4 Nm
The housing of the vibration monitoring unit must be earthed via the fixing –
through the machine earth of the mounting surface or through a separate pro-
tective conductor (PE).
To obtain precise measurement values, the vibration monitoring unit must be
fixed to the mounting surface in a friction-locked manner.
Auxiliary structures for fixing are to be avoided. If unavoidable, make them as
firm as possible!
Earth/ground loops are amongst the most common problems in measurement
set-ups with sensitive sensor technology. These issues arise due to unintentio-
nal differences in potential in the electrical circuit between the sensor and eva-
luation unit. As a countermeasure, we recommend our standard earthing con-
cept or, depending on the application our Alternative earthing concept
Ensure that the earth connection is electrically secure.
