Voltage: Fluctuations in the line voltage should not
exceed 10% of the rated nominal voltage shown on
the data plate.
Frequency: 6750 Proximate Interface units can be
operated from either a 50 or 60 Hertz power supply
without affecting their operation or calibration.
Current: The total current drawn should not exceed
the rating shown on the data plate on the unit by
more than 10 percent.
