7.2.1
Configuration of the secondary voltage and current ranges
The secondary voltage and current ranges are automatically configured during the automatic calibration function
(AUTOCAL). The voltage is configured in the range from 0.4 VAC to 120 VAC and the current in the range from
30 A to 500 A. If the voltage and / or current are outside of the permissible range, a detailed error message
appears on the controller (
section 8.19 "Error messages" on page 50).
If the secondary current I
2
is less than 30 A, the secondary high-current wire must be laid twice (or several times)
through the PEX-W4, or PEX-W5 current transformer (
ROPEX Application Report).
