1.6.8 Start-Up Procedure (Parallel UPS) (continued)

•Switch on the bypass input circuit breaker switch 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 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 the other UPS system 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 (reserve) mode to online (normal) mode at the same time. The “BYPASS” LED will darken and the “NORMAL” LED will illuminate.

•Check the output voltage of each UPS system. The phase 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 of each UPS system. Note: For more information on checking the output voltage of each UPS system, see section 10-6 of the owner’s manual.

1.6.9 Shutdown Procedure (Parallel UPS)

Warning: The UPS system shutdown procedure will eliminate the AC power output for all loads. Before shutdown, confirm that all loads are turned off or place the UPS systems in manual bypass mode to keep loads powered by the bypass (reserve) power source.

•For the UPS system you wish to shut down, press the OFF button for 3 seconds (until you hear a beep), then release the button. If the other UPS system can support the connected equipment loads alone, the UPS system that was turned off will shut down its inverter and its LCD screen will read “LOAD NOT POWERED”. The other UPS system’s LCD screen will read “ONLINE MODE”. If the total connected equipment load is too large to be handled by a single UPS system, both UPS systems will shut down their inverters and switch to bypass mode, and their LCD screens will read “ON AUTO BYPASS.”

•For the UPS system you wish to shut down, switch off the main input circuit breaker switch , then switch off the output circuit breaker switch .
