7.1.3.4 Connection
 If you have couplers with one transformer, connect the current inputs of the bay
units in series per phase (Figure 7-1, page 260).
 Record the isolator positions according to the configuration via the binary inputs of
the single bay units.
 Connect the TRIP command and transfer trip contacts of both bay units in parallel.
 In this case also connect further binary input functions (e.g. CBF initiation, CBF re-
lease, TRIP release) in parallel.
Figure 7-1 Connection of the current inputs of the bay units in bus couplers with only one cur-
rent transformer.
