Network Wiring for Ground Fault Detection
•
EXAMPLE 5:
Example 4 above shows the HS-NCM shared by two network nodes. If the network wiring is being monitored by an
adjacent node (refer to Figure 3.9), the Ground Fault switch (SW4) on the shared HS-NCM should be set to OFF. The power supply
Ground Fault detection for each is dependent on the requirements of their respective network nodes.
