5.4.4 Connecting the signal and magnet coil cables
The outer shielding of the signal and magnet coil cable is attached to the busbar via the clip (4)
(from the accessory bag in the connection area) (dual-compartment transmitter housing only).
In the case of the single-compartment transmitter housing, the outer shielding of the signal and
magnet coil cable is connected to the corresponding terminal for the signal and magnet coil
cable.
The shielding for the signal wires functions as a driven shield to transmit the measurement
signal.
The cable is attached to the flowmeter sensor and transmitter according to the connection
diagram.

Important (Note)
The power supply for the optional pre-amplifier is provided via terminals 1S and 2S.
The transmitter automatically detects the sensor and switches to the required supply voltage
on terminals 1S and 2S.
