INTRODUCTION
This appendix contains the information that your electrician needs to verify that your office meets the
electrical requirements of your HP 3000 Series 37. If you meet the requirements outlined in Section 2,
you do not need to have an electrician use this appendix.
POWER SPECIFICATIONS
The power specifications for the HP 3000 Series 37 are:
Line Voltage
The Series 37 requires a single phase power system with nominal voltage of:
100 - 120
VAC
+/-10% (90 - 132
VAC)
or
200 - 240
VAC
+/-10% (180 - 264
VAC)
Power voltages outside the specified operating range can cause intermittent system errors or shutdown.
Low voltage is the most common power problem, and is usually caused by inadequate wiring.
Line Frequency
The required line frequency is 48 Hz to 66 Hz. Line frequency usually depends on the local electric
company. Power is rarely generated by a motor inside your building. Incorrect line frequency can cause
intermittent system errors or display jitter.
