WAGO-I/O-SYSTEM 750 XTR
Firmware Update 279
750-495/040-00x 3-Phase Power Measurement Module 690 V
Manual
Version 1.2.0
No hardware adjustment values available with setting “Secondary Voltage
≤
120 V
RMS
” with firmware versions 05 and above
After an update from firmware versions < 05, there are no hardware adjustment
values for voltage measurement with a secondary voltage setting ≤
120 V
RMS
.
Therefore, the measured values are not available with the specified accuracy.
To use the existing hardware adjustment values even after the firmware update,
set a voltage > 120 V
RMS
on the I/O module under “Secondary Voltage” even for
voltages < 120 V
RMS
and adjust the value for the primary voltage accordingly.
