Electrical connection

The connections to the hood are made from above.

The connection point is a small electrical installation box with a terminal block. This small electrical installation box with a terminal block, the large electrical installation box with regulation, and the air induction fan must remain accessible (minimum 20 cm clearance from the ceiling) for harmonization, service, or potential repairs.

For the 2x36 W / 230 V fluorescent lights, connect the light fixture to the terminal block including the protective terminal via the conduit into the space with the light. The number of lights will depend on the dimensions of the hood. By arrangement, the lights can be connected to a junction box with a terminal block located on the top side of the hood. Connect L, N, PE to the designated terminals.

For the induction system 65 W / 230 V, connected to the terminal block in the junction box with the speed controller. 1 x power supply (a) CYKY 3 x 1.5, (b) CYKY 4 x 1.5) depending on the location of the switch: a) on the hood, b) off the hood for hoods OZV 9, 10, 11, 12, 13, 14, 15, 16. 2 x power supplies (a) CYKY 3 x 1.5, (b) CYKY 4 x 1.5) depending on the location of the switch: a) on the hood, b) off the hood for hoods OZV 17, 18, 20, 22, 24. Note: In the case of 2 x, it is also possible to have 1 x power supply and connect it to the hood, adhering to the applicable regulations. If access to the speed controller is restricted during installation or further mounting, it should be removed, replaced with a terminal block, and relocated to another suitable location, such as the distribution board or near the induction system switches. The controller must remain accessible for harmonization purposes.

The lighting and induction system are standardly interconnected, including the electrical installation box with regulation to the connection point – the electrical installation box with terminal block, where the entire hood is connected.

The switches for the lighting and induction air fan are not included in the delivery. The connection to the terminal block through switches on the hood can be ordered additionally. The placement of switches on the hood does not comply with applicable regulations due to the height above the floor.

From the factory, the speed of the induction fan’s electric motor is set to zero or minimal speed. Proper adjustment is then performed during harmonization by qualified personnel or service technicians.

Note: By agreement, if space above the hood is limited, these installation boxes can be placed freely on long connecting wires, allowing connection and access by pulling them out from the hood and returning them to the hood after connection and regulation.

Manipulating or arbitrarily adjusting the speed will not guarantee optimal function and may be a reason for the rejection of a claim or cause damage to the regulator or electric motor!
