3.7 Basic Initial Functional Test
CAUTION: Work carefully when performing these tests; hazardous voltages
are present on the input and output during this test.
Figure 3-7: Functional Test Setup
Refer to Figure 3-7 for the required functional test set up. Proceed as follows to perform a basic
functional check of the power system:
1. Verify the correct AC line input rating on the nameplate of the FCS unit(s) and make sure

2. Connect a suitable resistive or other type load to the output of the power source. Suggested
load values for the low voltage range rounded up to the nearest 0.1 Ohm are shown i
3-13.
For the high voltage range, the resistor values must be multiplied by four. For models
HV or –EHV voltage range option, recalculate these values by adjusting for the voltage
range value. Make sure the power resistor
