Power supply
3.1.1
Isolation
There are no galvanic isolation zones.
Figure 6: logical wiring scheme
As you notice from the figure, on the MPNC006 there are no zones that create an
isolation between the main power supply and the internal bus (TBUS). Only on each
terminal has an isolation barrier been created which allows the masses of each
terminal to be separated from one another.
3.1.2
System power supply
The MPNC006 requires a 24VDC (±15%) power supply as shown in the figure. The
system is protected from the power supply polarity inversion.
Before turning on the device
configure the Modbus setting , see chapter:
parameters configurations
Figure 7
Attention
wrong value for the power supply can cause a damage to the
device.
