DANGER! LETHAL HIGH VOLTAGE HAZARD!

All wiring should be performed by a qualified electrician, in accordance with the warnings in this manual and all applicable electrical and safety codes. Incorrect wiring may damage the UPS system severely and cause serious personal injury and property damage. Read Section 2 – Important Safety Instructions before proceeding.

6-1 Wiring Warnings

•De-energize all input and output power sources of the UPS system before installing cables or making electrical connections.

•Use flexible cable of sufficient length to permit UPS system servicing. The maximum cable length is 10 m (32.8 ft).

•Use ferrule caps to cover termination cables and prevent frayed ends from shorting on the UPS system terminal block.

•Use cabling rated VW-1, FT-1 or better.

•Use cable sleeves and connector clamps.

•The neutral conductor must be the same size as the current conductors.

•Tighten all connections with a torque of at least 3.95 N·m (35 in·lb)

•Confirm that all cables are marked correctly according to their purpose, polarity, phase and diameter.

•If the UPS system’s input/output power source is wye-wye, then “Neutral” and “Ground” must not be connected.

•If the input power source has VNG>0, install an isolation transformer before the UPS system and input power source, then connect the UPS system’s “Neutral” and “Ground” together.

•For equipment requiring a neutral connection to an IT power distribution system, the disconnect device must be a four-pole device and must disconnect all line conductors and the neutral conductor. If a disconnect device interrupts the neutral conductor, it must simultaneously interrupt all line conductors.

•Allow the batteries to charge uninterrupted for 24 hours after the initial wiring connection.

•Observe proper polarity by connecting negative to negative and positive to positive. Failure to observe proper polarity will damage the UPS system and create a serious risk of personal injury and property damage.

•Observe proper phase by connecting R to R, S to S, T to T and N to N. Failure to observe proper phase will damage the UPS system and create a risk of personal injury and property damage.

6-2 Wiring Preparation

•De-energize all input and output (AC and DC) of the UPS system and external battery cabinet (if present).

•Mark all cables according to their correct purpose, polarity, phase and diameter.

•Review the diagrams in Section 6-3and Section 6-4to familiarize yourself with the terminal blocks.

•Consult the table in Section 6-5to find the correct electrical input/output characteristics for the UPS system.

Note: If the UPS system’s input/output power source is wye-wye, then “Neutral” and “Ground” must not be connected. If the input power source has VNG>0, install an isolation transformer before the UPS system and input power source, then connect the UPS system’s “Neutral” and “Ground” together.

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.

Additionally, the UPS features multiple communication ports, including RS-232 and USB interfaces, ensuring compatibility with various devices and ease of integration into existing systems. It also supports SNMP protocols, allowing for seamless integration with network management systems.

Overall, the Tripp Lite SU80K combines high performance, advanced features, and user-friendly management options to create an ideal solution for businesses that require reliable and efficient power protection for their critical equipment. With its strong build quality and commitment to performance, the SU80K stands out as a versatile choice for ensuring business continuity in the face of power disturbances.
