PROBLEM AND POSSIBLE

CAUSE

SOLUTION

UPS OPERATES ON BATTERY ALTHOUGH NORMAL LINE VOLTAGE EXISTS

UPS input circuit breaker tripped.

Very high, low, or distorted line voltage. Inexpensive fuel powered generators can distort the voltage.

Reduce the load on the UPS by unplugging equipment and resetting the circuit breaker (on the back of UPS) by pressing the plunger in.

Move the UPS to a different outlet on a different circuit. Test the input voltage with the utility voltage display (see below). If acceptable to the connected equipment, reduce the UPS sensitivity.

BATTERY CHARGE AND BATTERY LOAD LEDS FLASH SIMULTANEOUSLY

The internal temperature of the UPS has exceeded the allowable threshold for safe operation.

Check that the room temperature is within the specified limits for opera- tion.

Check that the UPS is properly installed allowing for adequate ventila- tion.

Allow the UPS to cool down. Restart the UPS. If the problem continues contact APC at, www.apc.com/support.

DIAGNOSTIC UTILITY VOLTAGE FEATURE

Utility Voltage

The UPS has a diagnostic feature that displays the utility voltage. Plug the UPS into the normal utility power.

Press and hold the button to view the utility voltage bar graph dis-

play. After a few seconds the five-LED, Battery Charge, , display on the right of the front panel shows the utility input voltage.

Refer to the figure at left for the voltage reading (values are not listed on the UPS).

The display indicates the voltage is between the displayed value on the list and the next higher value.

Three LEDs light, indicating utility voltage within the normal range.

If no LEDs are lit and the UPS is plugged into a working utility power outlet, the line voltage is extremely low.

If all five LEDs are lit, the line voltage is extremely high and should be checked by an electrician.

The UPS starts a self-test as part of this procedure. The self-test does not affect the voltage display.

SUA1000US, SUA750RM1U specifications

The APC SUA750RM1U and SUA1000US are highly-regarded uninterruptible power supplies (UPS) designed to provide reliable power protection for critical electronic equipment. These models are part of APC's Smart UPS series, known for their superior performance and advanced technology.

The APC SUA750RM1U is a 750VA rack-mounted model that is perfect for data centers, server rooms, and other environments where space is at a premium. It offers a sleek 1U form factor, making it easy to integrate into existing rack systems. This unit features pure sine wave output, ensuring that sensitive electronics receive clean and stable power, which is crucial for maintaining optimal performance and longevity.

The SUA750RM1U also has a multiple outlet configuration, including both NEMA 5-15R and NEMA L5-30R outlets, allowing flexibility in connecting various devices. Its internal battery provides around 42 minutes of backup power at half load, which is vital during unexpected power outages. Additionally, the built-in LCD interface offers real-time information about the UPS status, such as power, battery life, and load level.

The APC SUA1000US, on the other hand, provides a larger 1000VA capacity, making it suitable for a wider range of applications, including critical systems and networking equipment. Like the SUA750RM1U, this unit also delivers pure sine wave output for superior performance. The SUA1000US is equipped with additional features such as automatic voltage regulation (AVR) that ensures the connected devices receive stable voltage levels regardless of fluctuations in the input supply.

Both models utilize APC’s SmartConnect technology, enabling users to manage their UPS systems remotely via a secure cloud connection. This feature allows for real-time monitoring, alerts, and notifications directly to a smartphone or computer, enhancing usability and ensuring peace of mind. They also support USB and serial connectivity for seamless integration with IT management software.

In addition to their impressive specifications, both the SUA750RM1U and SUA1000US incorporate advanced management features, such as energy-saving capabilities and customizable alerts. They are also engineered with a hot-swappable battery design, allowing users to replace the batteries without powering down connected equipment.

In conclusion, the APC SUA750RM1U and SUA1000US are exemplary UPS solutions that combine advanced technologies, top-tier performance, and intuitive management features. They are essential devices for ensuring the reliability and safety of sensitive electronic equipment in both professional and personal environments.
