DEMA CPM 310 G User Manual page 39

Terminal numbers and descriptions are given on the table below.
CAUTION!
The "Notes" columns on the table suggests a sample application and is not normative. "DC(+)" notes,
e.g., are given assuming that the circuit breaker, the power transformer and auxiliary devices are
cabled in the way that their common terminals are supplied with DC(-). If an application does not
correspond to the case here assumed, do not take the note columns into consideration and create the
actual cabling project required to provide the healthy operation of the system. ↺
