6 Preventive Maintenance

Preventive Maintenance is typically performed on a quarterly basis.

6.1.Equipment

1.4-Digit Voltmeter.

2.Clamp-on Ampere Meter.

3.Standard Insulated tools.

6.2.Inspection

Environmental Inspection

1.Ensure the dc system environment is suitable for operation.

2.Ensure that there is sufficient clearance around the system for service.

3.Ensure that there is no sign of damage to the dc system.

4.Contact monitoring personnel or disable system alarms before servicing the unit. This will allow the unit to be serviced without creating false alarms.

System Visual and Safety Inspection

WARNING: Hazardous energy levels are present on bare conductors in the dc distribution connection area of the plant. Accidental shorting of distribution conductors can cause arcing and high currents that can cause serious burns or other physical harm. It is recommended that:

•Any jewelry, rings, or watches be removed while working on this equipment.

•Handles of all wrenches, screwdrivers, cutters, and pliers are insulated.

1.Ensure that the dc wiring is properly installed, sized, terminated, and identified.

2.Ensure that the ac wiring is properly installed, sized, terminated, and identified.

3.Ensure that the battery wiring is properly connected to the System.

4.Ensure that the dc output over-current protection devices are adequate for the size of wiring installed.

5.Ensure that the dc Positive is bonded to central office ground (- 48 volt system).

6.Note the resistance of the ground bond.

7.Note any currents flowing in the ground.

8.Record ambient temperature.

9.Verify that the battery polarity is correct.

10.If battery disconnect devices are present, note the following for each device:

a)DC voltage rating.

b)DC current rating

c)Interrupting Current Rating

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.
