DIN Rail and Phoenix Connectors
Power supplied to the Instruments is fed through an assembly of
Phoenix Connectors snapped onto the DIN rail. Additional Phoenix
Connectors can be purchased directly from
www.phoenixcontact.com .

Green connect
ors are the “DC ground” connection.

Gray connectors are the “positive DC voltage” connection.
The pair of larger connectors (size 4) on the far left bring power into
the DIN rail from Main Line Power, Batteries, Solar Power System, or
Wind Power system.
The smaller pairs of connectors (size 2.5) are used to supply power to
various instruments in the enclosure. Additional connectors can be
added to power additional instruments as needed.
All
“power connectors” require a strong insertion force to fully seat the
connector.
The red plug-in bridge clips distribute power from a Gray connector to
the adjacent or the next Gray connector. Note the different sizes of
red jumper clips.
