Attention! 
•  Do not short circuit these signal lines. 
•  Never connect any  pins on  the same plug or to any other  plug on  the MICROSPACE 
MSB900/L.  The  +/-10  Volts  will  immediately  destroy  the  MICROSPACE  core  logic.  In  this 
case the warranty is void! 
•  Do not overload the output; the maximum output of the current converters is 10mA.
