Power Requirements
Before installing the system, be sure that the required ac power is available at all necessary locations.
• Three-wire power cables (which provide a safety ground) must be
used with all instruments.
• Air-conditioning equipment (or other motor-operated equipment) should not be placed on
the same ac line that powers the system.
• The table below lists the maximum VA ratings and BTU/hour ratings for all instruments in
the system. This table can be used to determine both the electrical requirements and the air
conditioning requirements of the system.
Notes:
(1) Values are based on 120 Vac supplie
d to each instrument at 60 Hz.
(2) The N5260A millimeter head controller supplies power to the test head
modules.
