• 17,065 BTU/hour (approx.) AC-input power
supply
• 17,730 BTU/hour (approx.) DC-input power
supply
Front panel LEDs
• INPUT OK AC-input power supplies:
• Green—Source AC voltage is OK. (Input voltage
is 85 VAC or greater.)
• Off—Source AC voltage falls below 70 VAC, is
not present, or the power supply is turned off.
DC-input power supplies:
• Green—Source DC voltage is OK. (Input voltage
is –40.5 VDC or greater.)
• Off—Source DC voltage falls below –33 VDC, is
not present, or the power supply is turned off.
• FAN OK • Green—Power supply fan is operating properly.
• Off—Power supply fan failure is detected.
• OUTPUT FAIL • Red—Problem with one or more of the DC-output
voltages of the power supply.
• Off—DC-output voltages within acceptable
margins.
