standard IEC 320 power receptacle located on the rear panel of the instrument. From
there it is routed through the ON/OFF switch located in the lower right corner of the front
panel.
AC line power is converted stepped down and converted to DC power by two DC power
supplies. One supplies +12 VDC, for various valves and valve options, while a second
supply provides +5 VDC and ±15 VDC for logic and analog circuitry as well as the TEC
cooler. All AC and DC Voltages are distributed through the Relay Board.
A 6.75 ampere circuit breaker is built into the ON/OFF switch. In case of a wiring fault or
incorrect supply power, the circuit breaker will automatically turn off the analyzer.
Should the power circuit breaker trip correct the condition causing this
