Installation Guide
Elise3
Galvanic isolation of the inputs and outputs is provided by using a separate power supply,
see figure 10.
Figure 10.
If galvanic isolation is not needed and the Elise3 is supplied by an external
12 Vdc/24 Vdc power source, the supply voltage can be taken from the 12-24 Vdc screw
connector by connecting +V Ext to "+" and GND Ext to "-", see
Figure 11. Example of AUX output without galvanic isolation and external 12/24 Vdc
If galvanic isolation is not needed and the Elise3 is supplied by the internal
230 Vac power source, the supply voltage must also be taken from the 12-24 Vdc screw
connector by connecting +V Ext to "+" and GND Ext to "-", see
Figure 12. Example of AUX output without galvanic isolation and internal 230 Vac
The inputs In 1 and In 2 are active when they are connected to 12 Vdc/24 Vdc.
