The preliminary startupverifies all electrical interconnections to ensure the installation was successful and thesystem operates properly.NOTE 2 Read this section of the manual and have thorough knowledge of UPS and SIAC-Boperation before attempting to operate any of the controls.66..11 SSiiddeeccaarr IInntteeggrraatteedd AAcccceessssoorryy CCaabbiinneett--BByyppaassss66..11..11 CCiirrccuuiitt BBrreeaakkeerrssFigure 54 or Figure 55 identifies and shows the location of the circuit breakers in the SIAC-B. The descriptionsprovide a brief overview of the SIAC-B breaker use.• Maintenance Bypass Breaker – The Maintenance Bypass Breaker (MBP) transfers the load from the UPSoutput to the bypass input feeder.• Maintenance Isolation Breaker – The Maintenance Isolation Breaker (MIS) isolates the UPS from thebypass feed and the load.• Bypass Input Breaker – (Optional – only three and four breaker configurations) The Bypass Input Breaker(BIB) provides a single point of input power control to the UPS on single-feed systems or bypass inputpower control to the UPS on dual-feed systems. Using the BIB easily removes power from the UPS forservicing.• Rectifier Input Breaker – (Optional – only four breaker configurations) The optional Rectifier Input Breaker(RIB) (four-breaker version only) provides a single point of rectifier input power control to the UPS on dual-feed systems and easily removes power from the UPS for servicing.66..11..22 UUssiinngg tthhee UUPPSS wwhheenn aann SSIIAACC--BB iiss IInnssttaalllleeddTo operate the SIAC-B:1. Remove the screw securing the bottom of the SIAC-B front panel. Lift the panel straight up to remove itfrom the panel hanger bracket at the top of the cabinet. Retain screw for later use.2. Close the SIAC-B bypass input feeder circuit breaker.3. If an BIB is installed, close the SIAC-B bypass input feeder breaker.4. If an RIB is installed, close the SIAC-B rectifier input feeder breaker.5. Verify that the SIAC-B circuit breakers are set as follows (see Figure 54 or Figure 55 for breaker locations):MBP OPENMIS CLOSEDBIB (if installed) CLOSEDRIB (if installed) CLOSED6. Start the UPS.
