Max. connectable cross-section: 1.5 mm²
Type: Screw terminal 1 (see Appendix A)
1) AI: analog inputs; P10/N10: auxiliary voltage; M or GND: ground reference
Caution
A current of 40 mA must not be exceeded during current measurement.
The common-mode range must not be infringed, that is, the analog differential voltage
signals can have a maximum offset voltage of +/- 30 V with respect to the ground potential.
If the range is infringed, incorrect results may occur during analog/digital conversion.
