This section first describes the terminal assignments, followed by
some typical connections.
Sections 3.1 to 3.5 contain specific instructions and the specifica-
tions for the individual terminals. The two inputs and outputs are as-
signed to two plug-in screw terminals. The two 15-pole screw-type
terminals are coded to prevent reversed polarity.
