Connecting the Power Supply
The power supply to the module is nominally 24V DC. The Class 2 power
supply connection provides power to the device and other XM modules
located on the DIN rail.
When wiring the DC input power supply to the terminal base unit, connection
may be made as shown in Figure 2.6. Also refer to Figure 2.1 on
.
