General safety instructions for assembly and operation
Warning! Life threatening electrical shock hazard!
A life threatening electrical shock hazard exists if the blower cable ends are connected
without first disconnecting the electrical power.
Always disconnect power prior to working on components that are electrically
energized.
Correspondingly, the electrical hook-up may only be performed by a qualified and
trained electrician who is trained in installation procedures in explosive environments.
Trained electricians are persons who are familiar with the assembly, installation, initial
startup and operation of the equipment/machine and possess an appropriate
qualification, or who are familiar with safety technology standards in the maintenance
and use of appropriate protective gear and accident prevention procedures as a result of
a corresponding education or training.
The installation depends on the requirements placed on the blower and the function
specific conditions at the installation location (on the machine or the equipment).
Only use spark-free tools when performing assembly and installation work in explosive
environments.
