Battery Visual and Safety Inspection

Check that the battery temperature probe is firmly attached to the battery.

Check the mechanical integrity of the battery framing, racking, or cabinet. Tighten where necessary. If there is a battery disconnect device fitted, ensure that it is properly connected and protected.

1.Check the general appearance and cleanliness of the battery. Clean if necessary. Use only approved cleaning materials.

Visually inspect each cell for the following, and clean and neutralize if necessary. Document discrepancies on Site form accordingly.

a.Cracks.

b.Case leaks.

c.Post-seal leaks.

d.Pressure relief valve leaks (VRLA only).

e.Case swelling (VRLA only).

f.Terminal corrosion and connector corrosion.

2.Check the torque of all battery inter-cell connector in accordance with specifications. Re-torque if necessary (annual only).

3.Measure and record ambient temperature.

6.3.Test

System Voltage Test

1.Verify with a voltmeter directly attached to the dc bus that the system voltage is correct.

2.System voltage should also agree with the battery float voltage set up in the battery parameters section. Be sure to take into account the effects of temperature compensation and battery recharge current limit.

Rectifier Current Share Test

Verify that the highest rectifier current and the lowest current are within 5 A of each other.

System Current Test

Verify the System current equal to the total of the rectifier currents. System current should equal the total current of the loads as well as any battery current.

Rectifier Alarm Test

1.Verify that all of the rectifiers report RFA Alarm is off.

2.Remove 1 rectifier and verify that you get a Minor alarm for Rect 1 of n failure on the controller and the customer remote alarm panel.

3.Remove the second rectifier and verify that you get a Major alarm for Rect 2 of n failure on the controller and the customer remote alarm panel.

4.After the fan has completely stopped spinning, insert a plastic pen or plastic screwdriver into the fan blade of one of the rectifiers and reinsert both rectifiers

5.Verify that you get the fan fail alarm on controller and the customer remote alarm panel.

6.Remove the fan fail device.

System Temperature Test

Verify that the system temperature is correct.

VS 50, VS 100 specifications

American Power Conversion (APC), a brand under Schneider Electric, is renowned for its uninterruptible power supplies (UPS) and provides a range of solutions for both commercial and personal use. Among their various product lines, the APC Smart-UPS 1000VA (VS 1000) and Smart-UPS 500VA (VS 500) stand out due to their features, technologies, and specifications tailored to different operational needs.

The APC Smart-UPS 1000VA is designed for advanced power protection, capable of supporting servers, network equipment, and more demanding applications. It features a pure sine wave output, which is critical for sensitive electronics, ensuring devices receive a stable and clean power source even during outages. The VS 1000 is equipped with an extensive battery backup, offering up to 9 minutes of runtime at full load.

A notable technology employed in the Smart-UPS 1000 is the Automatic Voltage Regulation (AVR), which maintains output voltage stability by adjusting boost and trim in situations of under or over voltage. The unit has an LCD interface, providing real-time data regarding load capacity, runtime, and battery health, enabling users to easily monitor and manage performance. Additionally, with its compact design, the VS 1000 can fit into various settings, maximizing space efficiency.

In contrast, the APC Smart-UPS 500VA targets smaller operations, offering a more compact solution for basic power protection needs. Like its larger counterpart, it also provides pure sine wave output, ensuring the safe operation of connected equipment. The VS 500 is designed for less intensive applications, making it suitable for desktop computers, network devices, and home office setups.

The 500VA model supports shorter runtimes, typically around 3 to 6 minutes under full load but is ideal for situations where downtime needs to be minimized. The Smart-UPS 500VA features similar Automatic Voltage Regulation technology, maintaining voltage stability under fluctuating conditions. However, it comes with a more straightforward LCD display, providing essential information on power status and battery levels without overwhelming the user.

In summary, the APC Smart-UPS 1000VA and 500VA cater to different user requirements, with the VS 1000 offering robust features for larger setups and the VS 500 serving as a versatile option for home or small office use. Both models integrate essential technologies such as pure sine wave output and AVR, showcasing APC’s commitment to high-quality power solutions. Whether for commercial or personal use, these units demonstrate APC's ability to provide reliable power protection tailored to diverse needs.
