Commissioning

m
Danger to life due to electric shock!
An electric shock can result in death or serious injuries.
> The commissioning may only be carried out by an authorised electrician.
m
Risk of injury due to ejected parts!
Loose parts can be ejected from the fan and cause injuries e.g. to the eyes.
> Wear protective glasses.
m
Risk of injury due to the rotating impeller!
The rotating impeller can sever or trap your fingers or arms.
> Operation only with mounted safety fittings.
> Do not reach into the rotating impeller.
The following inspection work must be carried out or checked before commissioning:
• Check the intended use of fan
• Check permissible transport media temperature
• Compare mains voltage with the performance data on the type plate
• 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 motor impeller unit must be freely accessible.
• Ensure that the inlet and outlet areas cannot be accessed by unauthorised persons.
• Check tightness of all connections (if necessary)
The direction of rotation may only be checked once the unit has been deactivated and the fan has come to
a standstill! Wear protective glasses when checking!
• Check free movement and direction of rotation of impeller by briefly switching on.
• Compare power consumption with rating plate data
• Test functionality of motor protection device. Check fan for inadmissible vibrations and noises 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!
• Check the waterproofing of the connection cable and tight clamping of the strands.
• Do not operate fan outside of specified characteristic curve (see catalogue / internet) . The fan must run at its spe-
cified operating point.
• In order to ensure sufficient motor cooling, a minimum speed/voltage, which also depends on on-site resistances,
wind pressure, etc., must be observed for voltage control through phase control. It must be selected so that a safe,
jolt-free start-up and operation are ensured.
5.4 Operation
m
Danger to life due to electric shock!
An electric shock can result in death or serious injuries.
> Before any maintenance and cleaning work or before opening the cover, the unit must be fully isolated from the
power supply.
m
Risk of injury due to ejected parts!
Loose parts can be ejected from the fan and cause injuries e.g. to the eyes.
> Wear protective glasses.
m
Risk of injury due to the rotating impeller!
The rotating impeller can sever or trap your fingers or arms.
> Operation only with mounted safety fittings.
> Do not reach into the rotating impeller.
m
Risk of burns due to hot surfaces!
Hot surfaces on the fan casing can cause serious burns.
> Wear suitable protective gloves.
Regularly check the proper functioning of the fan:
• Free movement of the impeller
• Power consumption in the range of the type plate data
• Check any vibrations and noises
• Formation of dust or dirt deposits in the casing or on the motor and impeller
• In case of problems with one of the aforementioned points, maintenance must be carried out according to the inst-
ructions in section 6.3 "Unit maintenance", page 10.
