Connection Plan
1)
Terminating resistor active: Bridge A to A’ and B to B’
2) Option
ATTENTION! Connection of sensors
The inputs 1T1, 1T2, 1T3 to 8T3 and RESET Y1, Y2, S1, S2 are not potentially
separated from output RS485. Temperature-sensors must have a sufficient
insulation.
Only signals according to SELV (Safety Extra Low Voltage) may be connected.
The pluggable terminals of the measuring inputs have a special contact-material
and may only be used for the connection of the sensors.
