Measuring input
If power supply is taken from the measured voltage
internal connections are as follow:
Application (system) Internal connection
Terminal / System
Single-phase AC current 2 / 11 (L1 – N)
4-wire, 3-phase 2 / 11 (L1 – N)
symmetric load
All other (apart from 2 / 5 (L1 – L2)
A15 / A16 / A24)
Bus Cable Termination
Both ends of the bus cable must be fitted with bus
terminators. This ensures that:
– the conductor has a fixed rest voltage,
– reflections in the cable are minimized and
– the bus has an almost constant load.

BF = Bus Failure LED
The slave is in the state “Baud Search” and does not
receive valid telegrams
