7. Electrical Connection
Make sure the terminals in the box are not under power (Use shielded cable 6 x 0.5
mm2 suggested in the technical data or stronger).
After powering the necessary programming can be performed.
Wire colours:
Green – relay C1 output
Yellow – relay CC output
Grey – relay C2 output
White – I, one of the points of current loop, power supply and HART (polarity
independent)
Brown – I, other point of current loop, power supply and HART (polarity
independent)
Black – GND, functional earthing and shielding point
Extension of the integrated cable:
Should extension be needed the use of connection box is suggested.
The shielding of the two cables should be connected and grounded at the signal
processing device.
