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 blacks, <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($). <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. Fallowing 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 /> er supply <br /> City of Santa Ana - RFP 21-100 IF <br /> Water Resources Panel Building Services <br /> Page 17 of 39 <br />
