(4) see VAC M-sheet 3101; storage temperature inside cardboard packaging (5) Constructed, manufactured and tested in accordance with IEC60664-1:2007 Isolated wires are preferred to fulfill the insulation coordination acc. to IEC 62955:2018, it is necessary to use insulated primary conductors that meet the requirements of the basic insulation for the rated voltage. If isolated primary conductors are used, the isolation coordination is acc. to: Reinforced insulation, Insulation material group 1, Pollution degree 2 and overvoltage category III. (6) The results are valid under following conditions: 55°C mean component ambient temperature by continuous operation (8760h per year); Environment condition: ground mobile, no dust or harmful substances, according to IEC61709; Fit equals one failure per 10^9 component hours. General description of sensor function: The sensor is sensitive to DC currents and can be used for fault current detection in EV-charging applications according IEC 62955:2018. In the event of a DC fault current, PIN3 and PIN4 will change its state from a low level to a high impedance state. Error conditions (e.g. an internal error) are signaled on PIN 1 (ERROR-OUT). The sensor only fulfills the switch-off characteristic of the IEC62955 standard (monitoring the residual current). An additional driver-circuit must be used for driving RCBO, RCCB or circuit breaker as defined in IEC62955. The sensor’s outputs are limited to max. 40V/50mA! Datum Änderung Patents added on sheet 1. CN-21-290 23.09.20 Final test: change value of TC1 and TC2; remove LV2. Minor change.

If a system fault is detected, PIN 1 is high impedance. In this case, PINs 3 and 4 will be set to a high impedance state (see tab. 1). A function test including an offset...
