Left: Main strands and load outputs (red: +24 V, blue: 0 V)

Right: Communication via the internal signal line (orange)

A maxGUARD station has three main internal connection 

channels: 

 

–

+24V main strand for +24 V potential

 

–

GND main strand for 0 V potential

 

–

Internal signal line for communication

The two main strands are connected to the power supply via 

a feed-in module and distribute the respective potentials for 

the entire maxGUARD station. 

The electronic load monitors form parallel junctions originat-

ing from the main strands.

Potential distribution terminals may be used to replicate the 

outputs of the load monitors as required.

The internal signal line enables communication within the 

maxGUARD station. Active feed-in modules, control modules 

and alarm modules connect the internal signal line to an ex-

ternal control board.

All connections between the modules of a maxGUARD sta-

tion are established using cross-connectors. 

The main connection channels are designed as double 

channels. For high currents, the main strands must each be 

equipped with two cross-connectors (see section 4.4). If nec

-

essary, the maxGUARD station can be extended by interleav-

ing the placement of the cross-connectors.

If a module cannot be connected to a specific main connec

-

tion channel, the corresponding cross-connection contacts 

will not be available. Installed cross-connectors will subse-

quently not be connected to the module and the individual 

contact elements of the cross-connectors do not have to be 

removed. White markings on the plastic tabs of the modules 

indicate the active cross-connection sockets.
