INPUT POWER SWITCH (Circuit Breaker)

The circuit Breaker is used as the main input ON/OFF control and protects the power
source from drawing excessive input current from the input AC line.
2. OUTPUT POWER SWITCH and INDICATORS
This Switch is used to control the output contactor of the AMX-Series Power Source.
Indicators show the state of the output contactor. If the power source shuts down for
the case of over-temperature or other internal fault, shutdown is reset when the
Output Power Switch is set to OFF and the fault has cleared. Refer to Paragraph 4.5
for details.
3. OUTPUT COUPLING INDICATORS
LED's which show the Output Coupling of the power source.
4. OUTPUT FORM INDICATORS
