Safety instructions for electrical connection

WARNING — Risk of electric shock

• Observe the safety rules of electrical engineering. Before taking off covers and before installing the electrics, shut down all supply circuits, switch off mains fuse, check that no voltage is present, secure against being accidentally switched back on and position a visible warning sign.

• Observe the applicable regulations for electrical installations, e.g. DIN EN 50110-1 and DIN EN 60204-1, in Germany in particular VDE 0100 with the corresponding parts → In case of non-observance danger due to electric shock, fire or short circuit.

• Only connect the fan according to the circuit diagram/wiring diagram. A permanent electrical installation is mandatory. Note the voltage and frequency stated on the rating plate. Use a mains isolation device with contact openings of at least 3 mm at each pole.

• Use cables of type NYM-O or NYM-J, with 3 x 1.5 mm² or 5 x 1.5 mm², suitable for the unit type.

• The degree of protection stated on the rating plate is only guaranteed if installation is undertaken correctly and the connection cable is inserted correctly.

• With protection class I, connect the PE conductor and check the connection.

• Perform a function test after completing installation, maintenance and repair work.

• Proceed with caution in the event of a malfunction. The fan may also be energized when at a standstill and may be switched on automatically by sensors (time delay, humidity etc.) or by the thermal switch in the motor winding. Maintenance and fault finding only permissible when carried out by qualified electricians.
