Verify no continuity, if multiple AC sources exist check each one separately. <br />e. Confirm there is no direct connection between each DC positive and ground. <br />Verify no continuity, if multiple DC sources exist check each one separately. <br />f, Confirm there is no direct connection between each DC positive and <br />common. Verify no continuity, if multiple DC sources exist check each one <br />separately. <br />g. Turn off all AC circuit breakers, open all AC fused disconnect terminal blocks, <br />and open all DC fused disconnect terminal blocks (if applicable) that serve <br />auxiliary DC loads (not fuses associated with 1/0 loops), and push in <br />Emergency -Stop pushbutton (if present). <br />h. Earth ground wire of AC control power source is connected to the ground bus <br />within the panel. <br />i. Connect and power -up AC control power source. Verify there is the correct <br />AC voltage (measured from line -to -neutral) on line and load sides of input <br />transient voltage surge protector (if present) and line side of AC main circuit <br />breaker. <br />j. Close AC main circuit breaker, AC main fuse, and/or AC main disconnect. <br />Verify that the correct AC voltage is present on the AC terminal blocks and on <br />the line side of all AC secondary circuit breakers. <br />k. Verify the AC main circuit breaker de -energizes and energizes all AC power <br />circuits in the panel. Close each AC secondary circuit breaker or fused <br />disconnect one -at -a -time. Verify that the correct AC voltage is present at each <br />of the devices served by these circuit breakers. <br />I. Verify each AC secondary circuit breaker de -energizes and energizes each of <br />the devices served by these breakers. <br />m. Verify receptacle is properly connected by testing with a receptacle polarity <br />tester. <br />n. If panel is equipped with a humidistat and panel heater, verify proper <br />operation of heater. <br />o. If panel is equipped with a cooling fan, verify proper operation of the fan. <br />p. Verify that the correct DC voltage is present on the output of the DC power <br />supply(s). <br />q. Verify that the correct DC voltage is present on the output of the DC <br />uninterruptible power supply (UPS). <br />r, Disconnect the battery backup to the DC UPS. Verify that DC voltage is <br />maintained on the output of the DC UPS. Following the test, reconnect battery <br />backup. <br />s. Open the AC main circuit breaker. Verify there is no DC voltage on the output <br />of the DC UPS. Following the test, close AC main circuit breaker and verify <br />the DC voltage is present on the output of the DC UPS. <br />t. Open the AC secondary circuit breaker for the DC power supply. Verify there <br />is no DC voltage on the output of the DC UPS. Following the test, close AC <br />circuit breaker for the DC power supply and verify the DC voltage is present <br />on the output of the DC UPS. <br />u. Electrically trip the AC main circuit breaker (Only if the breaker has manual <br />trip function). Verify that DC voltage is maintained on the output of the DC <br />UPS. Following the test, reset the AC main circuit breaker and verify the DC <br />voltage is present on the output of the DC UPS. <br />v. Electrically trip the AC secondary circuit breaker for the DC power supply <br />City of Santa Ana - RFP 21-100 <br />Water Resources Panel Building Services <br />Page 17 of 39 <br />
