Quick Installation Guide; Self-Limiting Overload; Starting Up - DGFLOW STEADYPRES V2.0 Manuel D'utilisation Et D'entretien

Before installing and using STEADYPRES:
- read this manual thoroughly and carefully and refer to the Safety Standards.
- Before making the connections, make sure that the ends of the line wires are not live.
- Make sure also that the electric power supply network is protected by thermal magnet and differential
protections according to the applicable Standard in force. The differential switch must be high-
sensitivity type
- Ground connections must be in compliance with Standards.
- Check that the plate data is that required and suitable for the system
- The cable section (power supply cable and connection cable between the inverter and the
motor) must be dimensioned according to:
o Voltage (230 V single-phase, 230 V three-phase, 400 V three-phase)
o Pump power
o Cable lenght
- The power supply cable and the motor cable must be sized to curb any power voltage drop within
3%.
- The power supply cable and the motor cable must be suitably shielded to comply with EMC
standards.
- In case of long cables between Inverter and pump motor, evaluate the application of inverter output
sinusoidal filter. It aids smooth running of motors eliminating negative effect of voltage peaks

Before running, this Manual must have been carefully read and the instructions followed; wrong
-
settings and operations are thus prevented that could cause operating faults
Before starting the system, the pumps must be primed (filling and air bleeding)
