AUXILIARY INPUT AND OUTPUT CONNECTIONS
CAUTION: The remote connections are insulated from the network power by a "reinforced"
type insulation (reinforced insulation according to EN 60730-1). Therefore it is recommended to
make electrical connections with a type of cable that guarantees double or reinforced insulation,
using insulated voltage-free contacts for the digital inputs.
Nettuno has various auxiliary connections located on the I/O board. The following diagram identifies
the various connections.
