Rail coupler
Description
The rail coupler interconnects the power supply voltage and the bus of the rail below to the modules via the sliding contact.
Overview
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.
