Use and Care Manual

e electrical installation may only be carried out by qualiﬁed electricians in compliance with the installation, operating

and maintenance instructions and the applicable national regulations, standards and guidelines:

■ ISO, DIN, EN and VDE speciﬁcations, including all safety requirements.

■ Technical connection conditions.

■ Safety at work and accident prevention requirements.

is list does not claim to be complete.

Requirements should be applied under one‘s own personal responsibility.

■ e electrical connections must be made as shown in the corresponding wiring diagrams and terminal diagrams.

■ e type of cable, size of cable and method of laying should be determined by an authorized electrician.

■ Low and extra-low voltage cables should be laid separately.

■ If no repair switch is integrated in the device, an all-pole mains disconnecting switch with min. 3 mm contact

opening must be provided in the supply line.

■ Use a separate cable inlet for each cable.

■ Any cable inlets that are not used must be sealed so that it is airtight.

■ All cable inlets must have strain relief.

■ Create equipotential bonding between the unit and the duct system.

■ Check all protective measures after the electrical connection work (earthing resistance, etc.)

■ Motor current and motor power must not exceed the values stated on the motor nameplate. e speciﬁed max.

fan speed must never be exceeded, otherwise the motor and fan will be destroyed by this overload and dissolved

or ﬂying parts can destroy other components.

11. ELECTRICAL CONNECTION

• Electricity warning (hazardous voltage)!

» Failure to observe the hazard may result in death, injury or damage to property.

→ Before performing any work on conductive parts, always disconnect the unit completely from the electri-

city supply and make sure that it cannot be switched back on again.

11.1. Unit supply cable / Electrical connection / wiring diagram

Connect the mains supply cable as shown in the wiring diagram. For the dimensioning of the line, observe the unit‘s

rating plate and the relevant guidelines. Appropriate protection with correctly dimensioned automatic safety breakers

(circuit protection breaker) must be provided.

e device must be connected according to the wiring diagram. For fans which are controlled by external control de-

vices, the corresponding operating instructions of the manufacturer must be observed.
