Settings on the module A23:
R2:
0 resistance as earth - reference potential M connection
On delivery, M is connected to earth. Remove this resistor only to avoid disturbances from earth loops, i.e. if the
electronic reference potential is otherwise connected to earth (e.g. via the reference potential connection
terminal of the power supply unit. The 0 resistor R210 on the A50 module must additionally be removed when
using the additional power suppy A50 (see Chapter 9.1).
S1:
Set the rated supply voltage with S1 (Piano DIP switch) (press down the applicable lever). Only one voltage
must be selected.
The setting of the system mains voltage on the switch S1 must correspond exactly with the one set on the
connected converters, thus guaranteeing a correct bypassing sequence and load current extraction (see
Chapter 4, Table 4.1 or 4.2).
S2:
The status of the bridging relays can be switched through to the "Warning" output (terminal X36) with S2
(DIP-Fix). When S2 is open, the "Warning" relay is opened only in the event of the excess temperature pre-
warning.
