The BCS is designed primarily as a hand-held operator terminal. As an alternative, a
bracket is available, which can be screwed onto any surface. The service terminal can
be clipped onto this bracket when not in use. The BCS may, however, also be mounted
in a control panel front, if required. The service cable, which incorporates the LON bus
and power supply, can be plugged into the service socket of a controller.
– Case for protection of service terminal (e.g. in tool boxes) and User Manual, R23
– Service cable, 3 m long
– Wall bracket. See Manual R21 section 04.20 for detailed installation instructions.
