Tripp Lite UPS Start-Up Procedure for SU120KX2 Models

8 – Start-Up, Shutdown and Bypass (continued)

8-3 Standard Start-Up Procedure (Single UPS—SUS)

•With the external battery cabinet connected, switch on the circuit breaker of the external battery cabinet.

•Confirm that the manual bypass circuit breaker switch Q3 is off.

•Switch on the bypass input breaker switch Q2 and then output circuit breaker switch Q4 . After a brief initialization process, the LCD screen will show “ON AUTO BYPASS”, the “BYPASS” LED will illuminate and UPS system output will be supplied by the input power source via the bypass path.

•Switch on the main input circuit breaker switch Q1 . If the AC input power source is normal, the UPS system is ready for start-up.

Note: In addition to the external battery cabinet breaker being turned on, the normal on-line running status of the four (4) circuit breakers is: Q1 , Q2 and Q4 On (closed); Q3 Off (open). This is shown in the diagram to the right.

•Press the ON button for 3 seconds (until you hear a beep), then release the button. The inverter will activate and synchronize with the bypass source, then automatically switch from auto bypass

mode to online (normal) mode. The “BYPASS” LED will turn off and the “NORMAL” LED will illuminate.
