It must be ensured that the same ground potential and ground
connections are used. If different ground potentials or ground
connections are used, compensating currents flow via the module
bus, 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.
Attention
In order to comply with radiation limit values in accordance with
EN 55 011/ 2 000, the supply lines of the XN-BR-24VDC-D module
for supplying the gateway with power are to be fed through a ferrite
ring. This is to be placed immediately next to the connection terminals.
From there on, it is not permitted to make connections to further
devices.
