BGX701-014-R03, User Manual for PT3 Transducers
8 PT3 network connections
Physical connections to the PT3 with the network are made on the front of the transducer. The connections are:
measuring voltages, measuring currents, analogue outputs, auxiliary power and connections to RS-485
communication module.
The connections must be performed in accordance with the measurement method and wiring settings
configured in the transducer. Choose the corresponding connection diagram from the figures below and ensure
that the correct polarity is followed.
Note:
The recommended size of the connection wires is 2.5 mm
2
and the terminal depth is 8 mm. Ensure that the
connections are made in accordance with the applicable regulations and best practices.
