•All circuit breaker switches should be off, including the breaker of the external battery cabinet.

•Confirm that no voltage potential exists between Neutral and Ground.

•Confirm that the input power source matches the rating (voltage, frequency and phase) of the UPS system.

Note: After start-up, the UPS system will perform a brief self-test and display the results on the LCD screen. After a successful self-test, the UPS system will provide AC power to the connected equipment load.
