9.2.6. AC POWER CONFIGURATION
The E-Series digital electronic systems will operate with any of the specified power regimes. As long as
instrument is connected to 100-120 VAC or 220-240 VAC at either 50 or 60 Hz it will turn on and after about 30
seconds show a front panel display. Internally, the status LEDs located on the Relay PCA, Motherboard and
CPU should turn on as soon as the power is supplied.
