WARNING
The fan must be isolated from the mains power supply and secure against being switched on again before
all maintenance and installation work or before opening the terminal compartment!
– The electrical connection and start-up must only be carried out by qualified electricians according to the information
in the terminal box / isolator switch and the attached wiring diagrams.
– All relevant standards, safety regulations (e.g. DIN VDE 0100), as well as the technical connection conditions of
energy suppliers are to be adhered to!
– Network configuration, voltage and frequency must be consistent with the rating plate information.
– In principle, the motors are wired in the clockwise field of rotation for clockwise rotation.
– Protective conductors, including additional equipotential bonding, must be properly installed!
– Check the waterproofing of the connection cable and tight clamping of the strands.
– The insertion of the supply line must be carried out by specialists! The connection line in the terminal box/ isolator
switch (IP 65) must compensate for the potential fan vibrations.
Installation accessories for the terminal box/isolator switch must meet the requirements of IP 65.
Never lay cables over sharp edges!

m
WARNING
The rotating impeller can crush fingers.
Ensure protection against contact before commissioning!
The following inspection work must be carried out or checked before commissioning:
– Check designated use of fan
– Check permissible transport media temperature
– Compare power consumption to rating plate data
– Check fan for professional electrical installation
– Check protective conductor connection
– Remove installation residues from the fan or duct
– Check all parts for tightness, particularly screws, nuts, protection guards. Do not loosen screws in the process!
Loose parts must not enter the fan.
– Check fan for solid mounting! The terminal box / isolator switch and motorised impeller unit must be freely acces-
sible.
– Ensure that the suction and outlet areas cannot be accessed by unauthorised persons.
– Check tightness of all connections (if necessary)
– Check free movement and direction of rotation of impeller by briefly switching on;
Wear protective glasses when
checking
.
– Compare power consumption to rating plate data
– Check fan for vibration and noise during test run. In case of excessive vibration and/or noise, it can be assumed that
the fan is operating outside of its operating range. In this case, contact the manufacturer by all means!
