Right screw: battery node simulation
Left screw: high current switch
The pin assignment of X4 Power I/O is located in Tab. 4-4 on page 46.
High current path configuration
• Battery node configuration (right screw as shown in Fig. 3-1) = Potential
of +VBAT is switched from X3 to HC_OUT_X
• High current switch configuration (screw installed on the left) = Potential
of HC_IN_X is switched to HC_OUT_X
Technical Data of the High Current Connections of X4 Power I/O
Note
For the high current switch configuration, ensure a defined polarity (e.g. posi-
tive potential between HC_IN_X to HC_OUT_X) between HC_IN_X and
HC_OUT_X. In case of non-observance, the current measurement will have an
inverted sign.
CAUTION!
For the high current switch configuration, ensure an external protec-
tive circuit (e.g. free-wheeling diodes, varistors, RCD networks...) to
protect against overvoltage/overload. Non-observance can destroy
the components or trip the inaccessible fuse of the respective chan-
nel.
