With the system supply, it must be ensured that the same ground
potential and ground connections are used. Compensating currents
flow via the module bus if different ground potentials or ground
connections are used, which can lead to the destruction of the Bus
Refreshing module.
All Bus Refreshing modules are connected to one another via the
same ground potential.
The power to the module bus is supplied via the connections 11 and
21 on the base module.
