6.6. ELECTRICAL CONNECTION

The CAD-COMPACT ECOWATT range are supplied without a complete operating control integrated in the unit. The elec-

trical components included in the unit (fans, by-pass servomotor, filter pressure switches and temperature probes) 

are supplied wired in an electrical cabinet located in one side of the unit. To access the electrical terminal block and 

conveniently make the electrical connection of the accessories it is advisable to remove the connection board, follow the 

following sequence:
1.  Loosen the 5 screws that are distributed by the cover of the electrical cabinet (Fig. 1)

2.  Open the cover and pull the metal plate on which the electrical terminals are located until it is outside the cabinet 

(Fig. 2).

3.  The electrical cabinet has a PG connector for the electrical power cable. Further of this, in a bag that is supplied 

inside the unit, there are 3 more connectors that can be used to route the control wiring to the control accessories or 

the control panel  of the building. Pass the necessary wiring through the connectors.

4.  Make the electrical connection to the control board and put it back inside the electrical cabinet, making it slide throu-

gh the existing guides (Fig. 3).

It is recommended to reduce the wiring lengths of the control maneuvers in order to reduce possible effects of the en-

vironment on the control signals.

To avoid interference that may affect the operation of the unit, it is recommended that the wiring be routed away from 

other electrical power lines, motors, refrigeration compressors, frequency inverters or the like.

This equipment complies with the Electromagnetic Compatibility Regulations that are applicable to them.

The use of shielded cables is recommended, although in environments with a high level of electromagnetic disturban-

ces, it may become necessary to shield the wiring using a metal tube. 

6.6.1. Wiring diagram

CAD-COMPACT models 500 to 3200 have plug-fans with EC motors 230V supply voltage, while the CAD-COMPACT 

4500 model have fans with a three-phase motor.

The electrical wiring consists of two phases: the power supply of the fans and the control wire.
Fans power wiring
The two fans are wired to the switch located on the lid of the electrical cabinet. To power the fans, wire the power 

line to the terminals of the switch.
