Start-Up Procedure Parallel UPS-MUS | Tripp Lite SU120KX2 manual

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

8-8 Start-Up Procedure (Parallel UPS—MUS)

•Connect the parallel configuration cable (shipped with each UPS) to the DB9 parallel configuration port of each UPS system. Note: Before starting up the Parallel UPS system, ensure that the “Parallel ID” is different for each UPS and parallel group is set to 2. See Section 10-5-5for more details.

Refer to Section 6-8 or 6-9for the appropriate settings of the parallel port DIP switches and parallel cable connections.

•With each UPS system’s external battery cabinet connected, switch on the external battery cabinet circuit breaker switch of each battery cabinet.

•Confirm that the manual bypass breaker Q3 on each UPS system is off. Switch on the bypass input circuit breaker switch Q2 of each UPS system. After a brief initialization process, the LCD screen will show “ON AUTO BYPASS” and the “BYPASS” LED will illuminate.

•Switch on the main input circuit breaker switch Q1 of each UPS system.

•Press the ON button of one of the UPS systems for 3 seconds (until you hear a beep), then release the button. The inverter will activate and synchronize with the bypass source. Press the ON button for each of the other UPS systems for 3 seconds (until you hear a beep), then release the button. When the inverter of each UPS system is operating normally, they will automatically switch from auto bypass mode to on-line (normal) mode at the same time.

The “BYPASS” LEDs will turn off and the “NORMAL” LEDs will illuminate.

•Check the output voltage of each UPS system. The phase voltage deviation between each UPS system should be less than 5V. If the phase deviation is within the acceptable range, switch on the output circuit breaker switch Q4 of each UPS system. Note: For more information on checking the output voltage of each UPS system, see Section 10-4.
