EMC disturbances may occur by changing the length of the cables, their position, the type of motor used, etc. When conditions of disturbance towards other devices occur, contact the manufacturer to evaluate additional solutions to reduce electro-magnetic disturbance. flowcon VSD - S.MT Inverter... -
Page 10: Installation Hydraulic Connection
Installation Hydraulic Connection The Flowcon VSD - S.MT Inverter must be installed on the pump delivery side, either upright or horizontally and respecting the flow direction shown by the arrow on the cover. The pump outlet water flows through the device before being distributed to the various appliances connected. -
Page 11: Electrical Connection
If the device is used in one of the following situations: temperature of the fluid used higher than 30°C ambient temperature higher than 35°C Cables with a thermal resistance of at least 100°C must be used for the power supply and motor cable. flowcon VSD - S.MT Inverter... -
Page 12: Line Connection
Line Connection The device has a single-phase 230 Volt 50/60Hz power line. The electrical system to which the equipment is connected must comply with the safety regulations in force and must therefore be equipped with: - An automatic magnetothermal switch with high breaking capacity and with a trigger current proportional to the capacity of the pump installed (see chart below) - Earthing with total resistance in conformity with local standards and in any case never over 100Ω... -
Page 13: Pump Connection
Three Phase Pump The Flowcon VSD - S.MT Invertercan be fitted on three-phase pumps with a 230Vac power supply therefore a delta configuration. When used with a submerged pump the motor must be ordered from the manufacturer with a factory-installed delta connector. -
Page 14: Auxiliary Connector Connection
The Flowcon VSD - S.MT Inverteris fitted with a special connector for an auxiliary contact so that additional functions can be exploited by interfacing the device with external equipment. - Page 15 The connection terminal is removable and may be connected to the I/O board after having carried out the electrical connections. The expansion board provides an auxiliary input and output. Refer to the documentation supplied with the board for the electrical characteristics and method of connection. flowcon VSD - S.MT Inverter...
