The two pole connector is based on
the 3 pole variation with one pole left
empty.
Basically there are three variations: a
connector for low-voltage applications
(e.g. LEDs), a connector for AS
Interface and a connector for
applications covering protection class
II. The latter are downward compatible
with the 3 pole system with ground
connector (RST 20i3). Thus you can
change from the system with ground
connector to the 2 pole system – but
not vice versa!
Both connectors are mechanically
coded. This means that only associated
pairs of male and female can be
connected with the correct polarity.
You therefore have the security of
a clear separation of different
applications without having to redo
any incorrect connections.
The color of the connectors indicates
the links that belong together.
