8700 W AC-Input Power Supply
Remote Power Cycling Feature
The 8700 W power supply is equipped with a remote power cycling feature that allows you to remotely
turn on or turn off the power supply through an external relay controller box. Figure A-18 shows a
typical remote power on/off setup. A three-position terminal block and a switch, located on the lower
right quadrant of the power supply faceplate (see Figure A-17), provide the interface to the external relay
controller box.
Front panel LEDs
INPUT OK 1, INPUT OK 2, and
INPUT OK 3
• Green—Source 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.
220VAC 1, 2, and 3
• Green—High-line AC is present on the respective
AC inputs. (Input voltage is 170 VAC or higher.)
• Off—Source AC voltage falls below 170 VAC, 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—One or more of the power supply DC-output
voltages is out of the normal operating range:
– For +3.3 VDC output: 2.7–3.0 VDC (min);
3.6–3.8 VDC (max)
– For +12 VDC output: 10.5–11.5 VDC (min);
12.6–13.0 VDC (max)
– For +42 VDC output: 38.0–40.0 VDC (min);
45.0–52.0 VDC (max)
• Off—All DC-output voltages are within normal
operating ranges.
