750-495/040-00x 3-Phase Power Measurement Module 690 V
voltage is monitored as a voltage input signal; with all other topologies, the
phase voltage is.
Voltage clipping due to input overloading is signaled by the "G" LED and
current clipping by the "C" LED.
All 3 error states are also indicated in the process image by setting the
corresponding bits in "Expanded status word 1", byte 2.
The clipping limit is:
- 252 V
Voltage" setting
- 505 V
Voltage" setting
2. The I/O module is designed for operation at a constant line frequency
between 45 Hz and 65 Hz. With a constantly changing line frequency, the
measurement errors can be greater than indicated in section "Measurement
Accuracy."
3. All 3 phases of the 3-phase network must be connected.
Observe limit values
Ensure that all limit values indicated in the technical data are observed. Values
above or below the limits can lead to destruction of the device.
Note the firmware update information
Performing firmware updates in the field can have effects on measurement
accuracy.
Note the corresponding information in the section "Firmware Update."
Measurement Accuracy in Phase Angle Measurement
Measurement accuracy for phase angle measurement decreases with weaker
current and voltage signals.
