Page 7: Warranty
This device complies with the directive ROHS 2002/95/EC. Description Flowcon VSD - B Inverter is an electronic control device for single phase electric pumps which enables automatic start-up and shutdown of the pump, protecting it in the event of adverse operating conditions (failure of water supply, motor overload, risk of ice). -
Page 8: Dimensions
In both operating modes, the device protects the pump from dry running in the absence of water on intake, by means of a combined control on flow and pressure.Operation of twin pumping units is admissible only in "P+P" mode. Dimensions Technical Data Mains power: single phase 115-230Vac ±10% - 50/60Hz... -

Page 10: Installation Hydraulic Connection
Installation Hydraulic Connection Flowcon VSD - B Inverter Inverter must be installed on the pump delivery in a horizontal or vertical position, in observance of the flow direction indicated by the arrow on the cover. The water on the pump outlet passes through the device for subsequent distribution to the various utilities. - Page 11 Connect the intake lines of the pumps to a common manifold and install one inverter on the delivery line of each electric pump. The device outlet couplings must be connected to a single delivery manifold, which must be connected to the expansion vessel. flowcon VSD - B Inverter...

Electrical Connection Insert the electric wires in the cable clamps, observing the correct order of assembly for all components Tighten down the threaded nuts to avoid traction and rotation of the cables from the exterior. The central cable clamps for the auxiliary contact is blank; if you wish to insert a wire for remote control (or electric float), pierce the plastic nut by means of a screwdriver after removing the nut from the unit. -
Page 13: Line Connection
The type of electric cable must correspond to the conditions of use (use in domestic rooms, dry or wet, for installation indoors or outdoors). Pump Connection Flowcon VSD - B Inverter can be installed on single phase pumps with 230Vac power supply, already fitted with capacitor. Therefore at the time of electrical connections, ensure that... -
Page 14: Auxiliary Connector Connection
Auxiliary Connector Connection The Flowcon VSD - B Inverter is equipped with a connector to make auxiliary contacts available for additional functions, interfacing the device with other external equipment. The functions of each terminal depend on the settings of the parameter “Aux. Con.” According to the diagram below. - Page 15 5 and 6 provide a relay output that is activated in the event of an alarm. The parameter "Aux. Con.” can only be set to “4” if the current operating mode is “P+P” (pressure+pressure). flowcon VSD - B Inverter...

Page 16: Start Up
After making all the electrical connections and ensuring the correct condition of all components, close the unit cover and power up the system. The Flowcon VSD - B Inverter Inverter starts up the pump automatically to enable circuit filling. If the pump does not start, or anomalous vibrations are detected, ensure correct connection of the pump and relative capacitor. -
