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.

American Power Conversion 1000, 750VA user manual Utility Voltage

1000, 750VA specifications

American Power Conversion (APC) is a leading name in the field of uninterruptible power supplies (UPS), offering a range of products designed to ensure power reliability for various applications. Among its notable models are the APC 1000, 1050, 1100, and 1400 VA units. Each of these models comes packed with features and technologies aimed at protecting sensitive electronic equipment from power disruptions.

The APC 1000 VA model is designed to cater to small server rooms, workstations, and point-of-sale systems. With a capacity of 1000 VA, this model can support several devices simultaneously, providing robust battery backup and surge protection. Its Automatic Voltage Regulation (AVR) helps maintain a consistent voltage level, safeguarding connected equipment from overvoltages and undervoltages. The unit is equipped with an LCD interface that displays real-time data regarding battery status, load levels, and estimated runtime.

The APC 1050 VA is a slightly upgraded version that offers a higher power capacity suitable for more demanding applications. This unit features advanced battery management technology, enhancing battery performance and prolonging its lifespan. With an extended runtime capability, the APC 1050 is ideal for critical systems that require longer power backup in case of outages. The hot-swappable batteries allow for easy maintenance without interrupting the power supply.

Moving up the range, the APC 1100 VA model provides additional features like built-in PowerChute software, which allows users to manage UPS settings and safely shut down systems during prolonged outages. This model is renowned for its compact design and energy efficiency, making it an excellent choice for both home office setups and small business environments.

Lastly, the APC 1400 VA model offers robust performance tailored for larger systems or more extensive networks. It comes with additional outlets and improved power distribution options, ensuring that multiple high-draw devices can be supported at once. This model is particularly beneficial for IT environments where equipment uptime is paramount.

In summary, APC’s 1000, 1050, 1100, and 1400 VA UPS models are engineered with advanced technologies such as AVR, enhanced battery management, and comprehensive monitoring systems. These features help provide reliable power protection and performance, making them essential components for anyone looking to safeguard their electronic investments against power fluctuations and outages.
