Creating Potential Groups
Bus Refreshing and Power Feeding modules can be used to create
potential groups. The potential isolation of potential groups to the
left of the respective power distribution modules is provided by the
base modules.
Attention
Ensure that the correct base modules are planned for when using
Bus Refreshing modules.
