WARNING
The supply common (Pin 5) and the shielding (Pin 15) must be
connected at the supply unit with protective ground.
Incorrect connection, incorrect polarity or inadmissible supply voltages
can damage the transmitter.
For cable lengths up to 5 m (0.34 mm
2
conductor cross-section) the
output signal can be measured directly between the positive signal out-
put (Pin 2) and supply common GND (Pin 5) without loss of accuracy. At
greater cable lengths, differential measurement between signal output
(Pin 2) and signal common (Pin 12) is recommended.
Reassemble the cable connector.
On the other cable end, terminate the cable according to the requirements
of the transmitter controller you are using.
