INSTRUMENT CONECTION
3.
The instrument supply leads should not be in proximity of the incoming low-potential signals.
Contactors, motors with larger input power should not be in proximity of the instrument.
The leads into the instrument input (measured quantity) should be in sufficient distance from all power leads and appliances.
Provided this cannot be secured it is necessary to use shielded leads with connection to ground (bracket E).
The instruments are tested in compliance with standards for use in industrial area, yet we recommend to abide by the above
mentioned principles.

Recomendation
1-2
connect L+ to (+) source
terminalconnected
3-4 termination of line 120 Ohm disconnected
connect at the end of line
5-6 connect L- to (-) source
terminalconnected
do not disconnect
RS 485 line should have a linear structure - wires (ideally shielded and twisted)
should lead from one device to another.
