EFC1P2
Control system
The control panel contains a potentiometer with a circuit breaker built into the control knob.
Installation of EFC1P
The supply cable must be dimensioned in accordance with applicable regulations and legislation. The conditions at the installation location, including temperature and the path of the cable must be taken into consideration.
The EC/FC motor has current overload and overheating protection. The motor needs no additional protection. The fault indication output of the motor cannot be used for external fault reporting, as it is used with the EFC1P.
When installing multiple single-phase ventilators with EC/FC motors in the same network with a shared neutral conductor, special requirements apply to the dimensioning of this conductor, as the current is not a pure sine wave. For example, if three single-phase ventilators with EC/FC motors are installed and divided between three phases, the current in the neutral conductor is equal to that of the three ventilators combined.
If you are fitting fan units to an existing installation, make sure that the neutral conductor can cope with the resultant load.
