change the UPS system’s output voltage by accessing the output setup menu described in Section 10-5-2. You must place the UPS system in
bypass mode before changing the output voltage. Do not connect your equipment to the UPS system’s output until you have set the proper	2
parameters.

9-2 Preliminary Checklist (Single UPS)

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

•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.

9-3 Standard Start-Up Procedure (Single UPS)

•1 If there is an external battery cabinet connected, switch on the circuit breaker A of the external battery cabinet. On the SU20KX or SU40KX, turn on the battery breaker on the back of the UPS.
