Installation

A connected controller, power supply or a rail coupler must be used at the left beginning of every DIN rail.

Follow the steps below to install the rail coupler:

1    Click the rail coupler onto the left beginning of the DIN rail.

2    Connect all four connection terminals (+, –, B1, B2) to the corresponding connection terminals of the connected controller (light), rail coupler or the power supply on the previous and next rails.

3    Each module is fitted with a sliding contact. Slide the sliding contact to the right until it clicks into the next module. This will ensure that the bus and the power supply are connected.


  • Bus cables can be used between terminals B1/B2 of any rail coupler and a control point.

  • A rail coupler can be interconnected to another rail coupler located in a different electrical cabinet.The cable length between both rail couplers should not exceed 20 m. If the distance between the electrical cabinets exceeds 20 m, you use a new power supply for the second cabinet.
