3. Connections GBM-8.2 

The module is equipped with modular terminals into which you insert the connection cables
and screw them tight.

3.1. Connecting the power supply and the track sections  

Connections to 2-rail systems

Connections to 3-rail systems

Connecting the power supply

Please note that all track sections must be in one booster circuit or must be supplied via a
common driving transformer.

 Please note: 

If you use a DC voltage transformer as the 

driving transformer, you must always observe the polarity when 
connecting it. If you use an AC voltage transformer, the polarity is 
not important.
