Installing signal interface connections in a parallel system
The installation of the signal interface connections in a parallel system is done by
following the aforementioned instructors. The signal polarity must be taken into
account when putting signal inputs and EPO wiring in parallel. Signal inputs can
be paralleled between the units, that is, the same contact can be used for several
units’ signal input signaling. This concerns also the EPO signal.
