Field bus coupler in interface fitted to insulated
DIN rail - TS/TPS, MW/TT series
IMPORTANT! Use only „insulated" DIN rails when fitting the field bus coupler.
Ensure that the DIN rail has no electrical contact with the earth of the power
source.

NOTE! Possible data communication error due to missing shield. Ensure that the
cable shield is connected to the plug at both ends.
IMPORTANT! Before starting up, check that the shield is connected to the robot
earth.
In systems with more than two power sources, wire the power sources in parallel.
NOTE! In order to avoid reflections and any transmission problems, fit resistors
to both ends of the field bus cable.
