Operation

Manual Startup

On occasion, a service technician may wish to start the UPS manually while performing diagnostic testing. The manual startup, like the auto startup, requires that the Rotary Switch be in the NOR- MAL position. To start the system manually, highlight MANUAL STARTUP and press the SELECT button on the navigation bar. This action brings up the MIMIC DISPLAY screen, prompting the Operator to close the Static Switch contactors.
