INSTALLATION
Before installing and using DGFIT:
-
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
(30 mA in class A for domestic application, class B for industrial
applications)
-
Ground connections
must be in compliance with Standards.
-
Check that the plate data is that required and suitable for the system
-
The
power supply cable
and the
connection cable between the inverter and the motor
must have:
o
3 wires (phase + ground) in single-phase applications
o
4 wires (3 phase + ground) in three-phase applications
-
The
cable section
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.
-
MOTOR CABLE LENGTH: If
the cable between the inverter and pump exceeds 15 m in length,
it is recommended to evaluate the application of a
sinusoidal filter
