16 Installing the XM Electronic Overspeed Detection System
Figure 2.2 XM System DIN Rail Grounding
1 Use 14 AWG wire. If it is desired to isolate the power supply because of possible ground loops, do not connect
24V Common to earth as illustrated in Figure 2.2. When the 24V supply is isolated from earth, it is
recommended to use an isolator on the RS-232 lines. Refer to the XM-220 Dual Speed Module User Guide.
The grounding wire can be connected to the DIN rail using a DIN Rail
Grounding Block (Figure 2.3).
