DAB MCE-150/C Nstrucciones De Instalación Y Mantenimiento página 43

Mains terminals and motor terminals may still have dangerous voltage when the
motor is stopped.
3. APPLICATIONS
The inverter of the MCE/C series is a device conceived for the management of circulation pumps allowing
integrated regulation of the differential pressure (head); it is thus possible to adapt the performance of the
circulation pump to the actual demands of the system.
This determines considerable energy saving, a greater possibility of control of the system, and reduced
noise.
The MCE-150/C inverter is designed so that it can be housed directly on the pump motor body.
