Operating voltagerange: –40 VDC through–72VDC
NOTE: Ifthe input voltagefrom the DC powersource drops below –37.5VDCthrough–39.5
VDC,the switching platform automatically shuts down.During automaticshutdown,the
circuitremains active. Whenthe input voltagereturns to–43 VDC through–44 VDC, the
switch automaticallystartsup again and the system returnstonormal operationwithin 30
minutes.No operatorinterventionis required.
