Network Wiring for Ground Fault Detection Network Configurations
• EXAMPLE 2: By setting the ground fault detect switch (SW4) on the repeater to the OFF position, both nodes may provide their
own ground fault detection (refer to Figure 3.6). The left node provides ground fault detection up to the repeater, and thus must be
one of the ground fault detection nodes defined on page 12. S2 (Port B) is set to the ON position to enable ground fault detection on
the left HS-NCM.
The Port A switch on the right HS-NCM is also set to the ON position, providing ground fault detection up to the repeater. This
node must also be one of the ground fault detection nodes defined on page 12.
• EXAMPLE 3: Ground fault detection is effective for a maximum of two serially connected (point-to-point) repeaters. Therefore, a
maximum of five HS-NCMs configured as repeaters can be connected in series when ground fault detection is required. Figure 3.7
shows how the ground fault detection switches must be arranged in order to achieve this maximum configuration.
• EXAMPLE 4: The HS-NCM can be shared between two network nodes. In this example, the HS-NCM is shared between two
nodes with separate power supplies. Ground Fault detection should only be enabled for one of the power supplies.
