should be recharged before conducting the following Test for proper operation (section 3.7) and to ensure that the UPS will provide expected run time. The UPS may be used immediately upon receipt, but may not provide expected run time in the event of a utility failure. The battery will recharge to full capacity within 6 hours when the UPS is plugged in and switched on. Once the battery has obtained a full charge, the UPS will maintain the charge as long as the UPS is plugged in, regardless of the position of the power I/0 switch.

3.6 Connecting Your Equipment to the UPS

To ensure that your computer equipment will be protected during a utility failure and that you receive expected run time, it is important that you determine the total power needs of the equipment you wish to protect with the UPS. The power requirements of your equipment should be less than or equal to the capacity of the UPS. The capacity rating of the UPS, in both Volt-Amperes (VA) and Watts (W), is given in the Specifications section of this manual.

The power demands of your equipment can be read from the Run Time Verses Load (section 9.0) chart or may be deduced from the equipment name plates. The Run Time Versus Load chart gives equipment power requirements (load) in VA for computer systems common in the office environment today. If your equipment is not listed in the chart, the following instructions will help you to determine their power needs.

3.6.1Computer equipment manufacturers must provide a load rating for their products. Usually, the rating is written on a name plate or label near the line cord. The rating may be given in units of Amps (A or Amax), Volt-Amperes (VA) or Watts (W). Jot down the load rating of all the equipment you wish to protect.

3.6.2All noted load ratings should be converted to Volt-Amperes (VA) so that all equipment power requirements can be added using the same units of measure.

3.6.3If load ratings are given in Watts (W), convert to an estimate of power requirements in VA by multiplying the value in Watts by 1.4.

3.6.4If load ratings are given in Amps (A or Amax), convert to an estimate of power requirements in VA by multiplying the value in Amps by 230. Unfortunately, many computer manufacturers overrate the power requirements of their equipment in order to be conservative and to cover the extra power demand of user added expansion boards. If the VA requirement that you have computed seems high or is already greater than the

Additionally, the BK600EI has a compact design, making it suitable for space-limited areas.

Conversely, the BK400EI is a slightly lower-capacity model, rated at 400VA, making it an excellent option for smaller systems or devices with lower power requirements. Similar to the BK600EI, it employs line-interactive technology, ensuring continuous operation even during power fluctuations. This model is designed with automatic shutdown software that protects devices from data loss during power outages, a critical feature for businesses that rely on information stability and integrity.

The K250EI stands out with its 250VA capacity, catering to entry-level applications. This model is perfect for those needing basic power protection for devices such as routers, modems, or small desktop computers. The K250EI is designed with overload protection, ensuring that devices are safeguarded against electrical surges and overload conditions. The LED indicators provide a quick visual reference for the unit's operational status, reducing user effort in monitoring performance.

All three models share essential characteristics, such as a compact footprint, user-friendly interfaces, and advanced battery management technologies that improve longevity and efficiency. They also come equipped with multiple outlets to ensure users can connect various devices simultaneously. Furthermore, each model is engineered to minimize the environmental impact, boasting energy-efficient designs that contribute to reduced power consumption.

In conclusion, the APC BK600EI, BK400EI, and K250EI UPS models exemplify affordable and effective power management solutions. With their high-quality features, advanced technologies, and protective characteristics, they are well-suited for home offices, small businesses, or individual users seeking reliable power backup and protection.
