Connection diagram
Drawings of the individual modules may be
ordered from Danfoss.
Format = dwg and dxf.
You may then yourself write the module
number in the circle and draw the individual
connections.
The supply voltage for the pressure
transmitter should be taken from
the same module that receives the
pressure signal.
