14.4 Remote

transmitter

When the transmitter is remote, the resistive system includes a connector DIN 43650A.

14.4.1 Electrical connection

For the electrical installation it is recommended to use multiple conductor cables, and not
single cables, in order to guarantee the cable gland will stay watertight. The connector has a
PG9 cable gland for cables with outer diameters between 4.5 mm and 7 mm. The
numbering of the terminals is the following:

In the female connector:

Terminal 1:

Resistive sensor

Terminal 2:

Resistive sensor

Terminal 3:

Not connected

Earth terminal: Not connected

14.4.2 Mounting

Once the electrical connection is made and the cable gland is tightened, connect the female
connector (A) to the male base (C) in the correct position, placing the gasket (B) between
them.
