•5 Press the ON button A 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 mode to online (normal) mode at the same time.

The “BYPASS” LED will darken and the “NORMAL” LED will illuminate.

•6 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 A of each UPS system. Note: For more information on checking the output voltage of each UPS system, see Section 9-6.

108-9 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 power source.

•1 For the UPS system you wish to shut down, press the OFF button

Afor 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”.

SU80K specifications

The Tripp Lite SU80K is a robust and reliable uninterruptible power supply (UPS) solution, designed to provide essential backup power to critical equipment in various environments such as data centers, telecommunications, and industrial settings. This high-capacity UPS offers 80 kVA of power, ensuring optimal protection for vital systems against power interruptions and fluctuations.

One of the main features of the SU80K is its advanced double-conversion technology, which provides clean and consistent power by converting incoming AC power to DC and then back to AC. This process not only isolates connected equipment from raw utility power, but it also ensures that sensitive electronic devices maintain a steady voltage and frequency, ultimately enhancing their performance and lifespan.

In terms of efficiency, the SU80K is equipped with an energy-efficient design that maximizes operation while minimizing energy consumption. The unit operates with an efficiency rating of up to 97% in online mode, which contributes to reduced operational costs over time and is especially beneficial for large-scale deployments.

Another notable characteristic of the SU80K is its modular design, which allows for flexibility and scalability. Users can add additional battery packs to extend runtime, enabling the UPS to adapt to changing power needs without requiring complete system replacement. This feature is particularly advantageous for growing businesses that need to expand their backup power capabilities progressively.

The SU80K also includes advanced monitoring and management options, with an optional network management card that enables remote monitoring via a web interface. This capability provides real-time data on the UPS’s status, battery health, and load levels, allowing IT administrators to make informed decisions to maintain system availability.
