power connector from the AC power receptacle. See Figure 7-8 on page 7-28 .
6. Check the LTU/CSU functionality according to instructions provided by the
manufacturer.
7. Verify that the green Power indicator on the front panel of the PS500 AC power
supply is lit, while the red Alarm indicator is not lit.
