In the power supply system of the air-handling unit and its accessories, a double-pole
switch must be foreseen with a minimum distance of 3 mm between contacts in each pole.
For correct management and use of the air-handling unit and its accessories, an EURAPO controller
is recommended. The control has to be chosen according to the requirements of the installation
6
and use of the unit.
On sizes 020–030 in standard configuration (example CBL00), it is not possible to
connect more than one motor in parallel to the same speed selector or controller.

For this requirement, a special optional card (CBL20) and the relevant electric
diagram are necessary.
Each air-handling unit is provided with:
8
•
Screw terminal board for the electrical connections, located inside the electric box;
•
Supporting relays for the three fan speeds, installed in the electric box only for sizes 040 –
050 – 060 – 070;

•
Electric wiring diagram, specific for the ordered unit and its accessories, located on the
electric panel;
•
Ground protection terminal marked with the symbol

1.
Remove the plastic cover of the electric box by loosening the screw.
2.
Connect the power supply (phase, neutral and earth) to the existing cable or directly to the
terminal block (Fig. 5 and Fig. 6). Passing through one of the available cable glands, complete
the connections to the terminal blocks as indicated in the wiring diagram (located inside the
electrical panel) and in the diagram of the regulator sent with the unit. Keep the cables with
mains voltage (230V) separate from those at very low voltage (BUS cables, NTC probes, etc.).
3.
Fix back the plastic cover of the electric box to the base with the screw (Fig. 5a and Fig. 6a).
