Electrical connection
m Danger to life due to electric shock!
Before any maintenance or installation work or before opening the terminal compartment, the device is to be fully
isolated from the power supply and secured against unintended restart!
− The electrical connection must be carried out only by a qualified electrician in accordance with the data in the termi-
nal box and enclosed wiring diagrams.
– The relevant standards, safety regulations (e.g. DIN VDE 0100) and the technical connection conditions of the local
electricity supply companies must be observed.
– The information on "Electrical circuit systems" must be observed.
– The information on "Trigger devices" must be observed.
− The electrical connection must be designed so that the fan operates at nominal speed in a smoke extrac-
tion situation until a mechanical failure. In this respect, any form of speed control, motor protection and
vibration monitor must be bridged and must not cause the deactivation of the fan.
− Connection data must comply with the information on the motor rating plate.
− The introduction of the supply line must be carried out professionally! The connection line in the isolator switch must
compensate for the potential fan vibrations.
− Never lay the lines over sharp corners.
− Security components, e.g. safety grille may not be dismantled, bypassed or disabled.
− Further operations see the following section "Commissioning".
− Earth connections, including any supplementary equipotential bonding must be properly installed!

Commissioning
m The rotating impeller can crush fingers/limbs .
Ensure protection against contact before commissioning!
Wear protective glasses when checking the direction of rotation!
Wear suitable protective clothing.
The following inspection work must be carried out or tested before the initial commissioning:
– The transport safety device must be removed before the functional test!
– Check for operation according to the intended purpose of the fan
– Check permissible air flow temperature
– Compare power supply voltage with data on the rating plate
− Check fan for solid fastening and professional electrical installation, check jumpers in the electrical
connection if necessary.
– Check all parts especially screws, nuts and safety grilles for tight fit. Without loosening screws!
− Check unhindered running of impeller.
− Check minimum air gap according to table in section 3.5.
− Ensure that the suction and outlet areas cannot be accessed.
− Compliance of direction of rotation and airflow direction. Check direction of rotation of impeller; by short-time acti-
vation.
− Perform visual inspection for forgotten or loose parts.
− Compare power consumption with rating plate.
− Test functionality of motor protection device, check bridging in case of fire!
− Check protective conductor terminal.
− Check sealing of connection cable in the terminal box and fixed clamping of wires.
− Commissioning may only take place if protection against accidental contact is ensured.
− Check sealing of all connections (if necessary).
− Remove assembly residues from fan and duct.
− Check fan for inadmissible vibrations and noises during test run.
− Do not operate the fan outside the specified performance curve (see catalogue / internet). The fan must run
at its specified operating point.
− Complete the attached commissioning report (see page 20) and present in case of a warranty claim.
− The attached commissioning report must be completed and delivered to the system operator.
