Step
Action
1
Mark the intended installation site following the installation dimensions
2
Drill the mounting holes into the wall with an adequate tool.
5
Depending on the accessibility of the cable connections we recommend to connect all cables (current,
CAN etc.) before mounting the device.
Important: A cable connection must only be established if the main switch is OFF. Check the cables
with regard to correct polarity and ensure that the max. permissible operating voltage is not exceeded.
Please do not forget the terminating resistor if the device is the first or last participant on the CAN bus.
