6�4 Installation example: Suspended ceiling
When installing directly in pipeline, e.g. in suspended ceilings (see Fig. 5), the units with small installation
depths fit everywhere. Installation is possible in any position – horizontal, vertical and diagonal.

6�5 Electrical connection / Commissioning
m
DANGER!
Touching live parts will lead to electric shock�
Isolate the unit from the mains power supply before connection!
m
DANGER!
Waiting period of at least 5 minutes!
When using capacitors, there is a danger to life after deactivation due to the direct touching of live parts� Ter-
minal compartment access is only permitted after the power supply is disconnected and a 5 minute waiting
period�
m
WARNING!
The rotating impeller can crush fingers�
Ensure protection against contact before commissioning!
– The electrical connection and initial commissioning must only be carried out by qualified electricians
according to the information in 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!
– A multipole mains section switch/isolator, with a minimum contact opening of 3 mm (VDE 0700 T1 7.12.2/
EN 60335-1) is mandatory!
– Network configuration, voltage and frequency must be consistent with the rating plate information..
– Check the waterproofing of the connection cable and tight clamping of the strands.
– Metal cable screws must not be used when connecting to plastic terminal boxes.
– Insert the supply line so that no water can get in along the cable in case of water exposure.
– Check designated use of fan
– Compare mains voltage to rating plate data
– Check fan for solid mounting and professional electrical installation
– Check all parts for tightness, particularly screws, protection guards. Do not loosen screws in the process!
– Check free movement of the impeller. Wear protective gloves when checking unhindered running of impeller!
– The motor will start automatically when the operating voltage is applied, a setpoint specification exists
(0-10V) and a release exists (type-dependent)� Accordingly, appropriate measures must be taken to protect
against access to touchable, dangerous, moving parts�
– When the impeller is turned by hand, there will be slight resistance due to the permanent magnets. This is for
technical reasons and it is not a malfunction
– Compare power consumption to rating plate data
– Check protective conductor connection
If a residual current device is installed in the supply line of the EC fan, the residual current device must have the following
technical features:
Type A or B with a rated differential current of 300 mA and delayed triggering (super resistant, characteristic K).
The EC fan has a leakage current of <= 3.5 mA, calculated according to DIN EN 50178 image 4.
ATTENTION:
The EC fan is intended exclusively for fixed installation, connection via plug is not permitted.
6�6 Operation
In order to ensure the proper functioning of the fan, the following must be checked regularly:
– Formation of dust or dirt deposits in the casing or on the motor and impeller
– Freewheeling of impeller. Wear protective gloves when checking freewheeling of impeller!
– Occurrence of excessive vibration and noise
If excessive vibration or noise occurs, maintenance must be carried out according to the instructions in CHAPTER 8.
