Page 5: Safety Instructions
Only use manufacturer’s and manufacturer recommended accessories with this equipment. Failure to do so may damage the equipment beyond repair. The RCMB101 is designed in compliance with the requirements described in UL 2231-2, "Standard for personnel protection systems for electric vehicle (EV) supply circuits: Particular requirements for protection devices for use in charging systems."... - Page 6 Safety Instructions NAE1045320 / 11.2011...

Page 7: Function
2.2 Description The RCMB101 is a ground fault current module (CCID20) for monitoring AC/DC ground faults in elec- tric vehicle charging stations. The CCID20 shall be mounted into the charging station as an open- type circuit board. The electrical connection is made with circuit board plug connectors. -
Page 8: Cyclical Self Test
Function 2.3.2 Cyclical self test Before each charging cycle, a reset with subsequent calibration has to be activated by the charging control electronics via the input X10. This requirement can only be met when sufficient supply volt- age +U /- U is available. -
Page 9: Control Input X10
Enabling for measuring operation Start of residual current measurement A RESET of the RCMB101 can be carried out at any time via the control input X10. NOTE: The ground fault current measurement is interrupted during this time. For activating the RESET function, a LOW level is to be applied across the control input X10 for at least T1 >... -
Page 10: Reset And Subsequent Calibration Of The Rcmb101
Function 2.6.2 Reset and subsequent calibration of the RCMB101 ~ ~ ~ ~ NAE1045320 / 11.2011... - Page 11 Once the calibration procedure is completed (X12 to LOW), calibration can be repeated as frequently as desired by applying a HIGH level at X10 for T2 = 50...100 μs. The RCMB101 starts the ground fault current measurement when a HIGH level is applied at X10 for at least T5 = 5 ms.

Page 12: Measuring Sequence Without Charging Electronics Reset
Function 2.6.3 Measuring sequence without charging electronics reset If a LOW level is applied across the control input X10 of the residual current monitoring module for T < 530 ms, no RESET will be carried out. The outputs X1 and X12 will remain unaffected. The residual current measurement will stay active. -

Page 14: Starting Sequence
Function 2.7 Starting sequence The RCMB101 is supplied by an external power supply. Supply voltage fluctuations can influence measurements. To exclude this effect (calibration is considerably affected!), the following starting se- quence is applied: The starting sequence of the module begins when a supply voltage of U 5 V is applied. - Page 15 Function Starting sequence Us+ >= 5 V X12 = HIGH US+ >= 11 V Offset measurement US+ >= 11 V 0,5 s X12 = LOW 0,1 s Start I-measurement Switch on test current through test winding 2,0 s Stop I-measurement Switch off test current 0,1 s through test winding...

Page 16: Values Outside The Permissible Measuring Range
If the ground fault current exceeds the measuring range ( 20mA), the RCMB101 will switch the Open-Collector output to HIGH once the measuring time T1 has elapsed. In comparison to the switching output X12, the voltage at the analog output X1 increases with a de- lay of U = 4.85 V within the time T2. -
Page 17: Measuring Range And Switching Times
2.9.2 Switching times without a contactor The time the RCMB101 needs for signaling a disconnection with switching output X12 is at least 10ms below the disconnection time required by the UL 2231 standard. Please consider that the actual interruting device/contactor chosen by the... -
