The RATH 2500-PWRUPS Power Supply is an emergency communication power supply designed for indoor use, providing backup power to essential systems during AC power outages. Manufactured by RATH, a company with over 35 years of experience in emergency communication, this power supply emphasizes reliability, quality, and comprehensive customer support.

Function Description

The 2500-PWRUPS system consists of an AC/DC power inverter and an 82Ah lead-acid battery. Its primary function is to convert DC power from the battery into AC power to operate connected devices when the main AC power source is unavailable. For supervised systems, it also includes supervision relays to signal primary power loss. The inverter contains components that can produce arcs or sparks, necessitating careful installation in appropriate environments. It is designed to provide a simulated sine wave output, suitable for a wide range of electronic equipment. The system is equipped with various protection features, including short circuit, overvoltage, overload, and ground fault protection, ensuring safe and reliable operation.

Usage Features

The 2500-PWRUPS is designed for straightforward installation and operation. It comes with pre-wired quick connectors for the battery and inverter, simplifying the setup process. The battery must be mounted securely using the included wall bracket and connected within 4 feet of the inverter. The device supports multiple acceptable orientations for mounting the inverter, including under a horizontal surface, in a horizontal position on a vertical surface, or on a horizontal surface, providing flexibility for installation in various environments.

For primary AC power loss, the system will either display battery voltage on a status screen (for non-supervised systems) or trip an attached relay (for supervised systems), indicating the transition to battery backup. In the event of secondary power loss (battery unplugged), the power supply will emit an audible tone and display specific error codes (E01, E05, or E12) to alert the user.

The system requires the use of RATH® approved wiring harness and battery (RP7701000B) to ensure proper function and maintain warranty validity. After installation, it is recommended to allow up to 12 hours for the battery to fully charge.

Maintenance Features

Maintenance of the 2500-PWRUPS primarily involves monitoring the battery and addressing error codes. The battery should be replaced every 3-5 years to ensure optimal performance. The manual provides a comprehensive list of error codes and corresponding actions to troubleshoot common issues:

E01 (Low battery voltage shutdown): Check battery status, recharge if necessary, verify proper DC cable size, and tighten loose connections.
E02 (High battery voltage shutdown): Check for external charging sources and disconnect if necessary.
E03 (AC output overload shutdown): Reduce the loads connected to the AC outlet.
E04 (Over temperature shutdown): Reduce AC outlet loads, check for blocked ventilation grille, and ensure ambient temperature is within limits.
E05 (Low battery voltage detected): Similar to E01, check battery status, recharge, verify DC cable sizing, and tighten loose connections.
E06 (AC output overload warning): Reduce the load connected to the AC outlet.
E07 (Over temperature warning): Check that the ventilation grille is not blocked.
E11 (Over temperature on AC transfer relay): Check that the ventilation grille is not blocked.
E12 (Battery bad or DC load connected to battery): Check battery; it should rise above 10VDC after 15 minutes.

The manual strongly emphasizes safety, warning against exposing the inverter/charger to moisture, operating it if damaged, or disassembling it due to internal charged capacitors. It also highlights the explosion hazard associated with charging unapproved batteries or operating the unit in environments with flammable materials, arcs, or sparks. Disconnecting both AC and DC power before any maintenance or cleaning is crucial.
