Power on the AC mains at the service panel by closing the switch or circuit breaker. - All LEDs illuminate for three seconds as part of the system initialization. - Each module powers on in sequence (with approximately 10 seconds between modules), synching up with the utility power. - The Utility LED (1) rapidly flashes green during this startup process. - The UPS enters Standby mode, indicated by the Utility LED (1) slowly flashing green, after all electronics modules have synchronized. - The system begins charging the batteries but does not assume the load. - The UPS will remain in Standby mode indefinitely until the UPS On command is received. NOTE: The time required to transition from Startup mode to Standby mode can range from 45 seconds to several minutes, depending on the charge status of the batteries. NOTE: On initial utility startup, you may receive an Inverter Uncalibrated alarm. Press the On button to start the autocalibration process, which lasts approximately 2 to 4 minutes. Until you start this process, the UPS will remain in Standby mode and continue to sound the alarm. NOTE: Verify that the UPS is NOT in Bypass mode.
