Stop running tests prior to mounting or disassembling the PA-adapter
To prevent loss of test data and in terms of a structured mode of operation you should
solely mount or disassemble the PROFIBUS PA-adapter BC-700-H1 when there is no running
test function.
Two light emitting diodes directly give a check-back indication with respect to the operational state of
the PA-adapter and to the DC voltage (supply voltage), see figure.

3.5.4 Bus connection
The supplied test equipment set allows to easily connect the BC-700-H1 adapter to the PROFIBUS PA
segment. Alternatively you can use a short length of PROFIBUS PA standard cable to connect the tool to
the bus.
In general it is sufficient to use PA+ and PA-
Protocol analysis, testing DC voltage level (supply voltage) and AC signal levels (MPB peak-
peak voltage) require only a proper connection to signal wires PA+ and PA-. To guard
against and prevent errors in test and parasitic coupling (EMC) it is additionally
recommended using cable shielding or interconnecting the shield connector.

Do not use in hazardous areas
The BC-700-PB and BC-700-H1 adapter must not be used in hazardous areas and must not
be connected to an intrinsically safe MBP-IS segment (blue terminals of fieldbus coupler; in
some cases blue bus cables).
