Installation
The safety instructions specified in chapter 1, section 1.2 must be observed!
Installation work on the bearing monitoring unit may only be carried out by qualified personnel. In particular,
the general and regional mounting and safety regulations for work on high voltage systems (e.g. VDE) must be
complied with as must the regulations concerning the use of personal protection equipment.
The unit is used for monitoring the roller bearings of fans. It is essential for the function/monitoring that the rotating ob-
