7.3 Replacing the Electronics Unit

The UPS allows replacement of a failed Electronics Unit without interruption of power to the load. The Isolation Unit is capable of autonomous operation and provides power to the load isolated from EMI/RFI noise and surges.

To replace a failed EU, follow the procedures listed below.

7.3.1Put the UPS into the bypass mode of operation by actuating the manual bypass switch at the rear of the EU. Note: Transfers to bypass mode using the manual bypass switch occur within 10 mS typically. The transfer back from the bypass mode occurs in 0 mS.

7.3.2Using a coin or large flat blade screwdriver, unscrew the EU separating screw and pull back.

7.3.3Using a phillips screwdriver, loosen the Battery Pack coupler lock at the rear of the EU and disconnect the pack coupler. Disconnect the Battery Pack communica- tions cable from the jack at the rear of the EU.

7.3.4If necessary, disconnect cables connected at the Computer Interface port and the Emergency Power Off interface.

7.3.5Grasp the EU at the slots shown in the illustration and pull straight up and away from the IU.

7.3.6Follow the above procedures in reverse to install the replacement EU. Once the replacement EU is installed, press any key to regain control of the UPS.

Note: Do not grasp the EU by the display and control p a n e l .

American Power Conversion 5000, 3000 manual Replacing the Electronics Unit

3000, 5000 specifications

American Power Conversion (APC) has long been a leader in the manufacturing of uninterruptible power supplies (UPS), and among its range of products, the APC 5000 and 3000 series stand out for their robust performance and reliability. These UPS systems are designed to ensure a continuous flow of power, protecting sensitive electronic equipment from fluctuations and outages.

The APC 5000 and 3000 models boast a range of key features that make them suitable for both commercial and residential applications. One of the primary characteristics is their high power capacity. The 5000 model provides a substantial 5000VA/4500W output, while the 3000 variant offers 3000VA/2700W. This enables users to connect multiple devices and critical loads without the risk of overload.

Both models utilize advanced double conversion technology, which ensures that the output power is consistently clean and stable. This technology is crucial for sensitive electronics, as it filters out voltage irregularities, providing pure sine wave output. This characteristic is particularly important for equipment like servers, data centers, and networking hardware, as it enhances their longevity and operational efficiency.

Another notable feature is their extended battery runtime capability. The APC 5000 and 3000 units are designed with hot-swappable batteries, allowing for easy replacement without interrupting the power supply. This enhances the overall reliability of the system, ensuring that even during maintenance, equipment remains operational.

In terms of connectivity, both models come equipped with multiple outlets for various plug types, as well as USB and network ports for monitoring and management. The integration with APC's PowerChute software allows users to manage power preferences, monitor battery health, and receive alerts when attention is needed. This level of monitoring is essential for facilities management teams, allowing them to ensure continuous operations without power-related disruptions.

The APC 5000 and 3000 also feature robust thermal management systems. With built-in fans, these units ensure efficient airflow and heat dissipation, protecting internal components from damage due to overheating.

In conclusion, the APC 5000 and 3000 series represent a powerful solution for those seeking reliable power protection. With their advanced technologies, multiple connectivity options, and serviceability features, these UPS systems stand out as trusted components in any power management strategy. Whether in a data center or a home office, the reliability and efficiency of these models make them invaluable in today’s power-dependent environment.
