  4.1 Rear mounting – Option 1 1 . Insert the ERC 102 into the cabinet . 2 . Attach the clips to each side of the ERC 102 . 3 . Place the front frame on to the ERC 102 and click it into place .

• Page 11: Unmounting

  1 . Disconnect the power cable and then the sensors . 2 . Use a flat head screwdriver (ideally the one supplied with the ERC 102 sample package) and insert it carefully between the front frame and the controller .
