4.0 Installation

4.11 Emergency Power Off (EPO) interface

The UPS may be switched off by a remotely operated Emergency Power Off control. Such a configuration is common in computer rooms and laboratories where, for safety reasons, power to the loads must be disconnected. The EPO interface is a six-position modular jack with an offset latch. Connection to a remotely located EPO switch may be accomplished as shown below.

Caution: The EPO interface is a Safety Extra Low Voltage (SELV) circuit and may be connected only to other SELV circuits.

Attention: L'interface de mise hors tension d'urgence est un circuit de sécurité à très basse tension qui ne peut être connecté qu'à d'autres circuits de sécurité à très basse t e n s i o n .

Beachte: Die Schnittstelle für die Notabschaltung ist eine Schutzkleinspannungs- Schaltung (SELV = safety extra low voltage circuit) und darf nur an andere

Kleinspannungs-Schaltungen angeschlossen werden.

Precaución: La interfaz de Parada de Emergencia es un circuito de seguridad de extra bajo voltaje, y puede conectarse únicamente a otros circuitos de seguridad de extra bajo voltaje.

Caution: The EPO interface is designed to monitor circuits that have no determined voltage potential. Such "closure circuits” may be provided by a switch or relay properly isolated from the mains. Connection of the EPO interface to any circuit other than a closure type circuit may cause damage to 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.
