Introduction

1.0INTRODUCTION

The Liebert® APM™ UPS is a transformer-free, hardware-scalable, online uninterruptible power system with 208/120V input and 208/120V output capability. The Liebert APM can operate with either a 50 or 60Hz input and provide a matching output. The rack mounted 15kVA/kW modules allow scaling the UPS’s capacity in 15kVA increments from 15kVA to a maximum of 90kVA in a single frame.

Optional transformers are available to add 480V or 600V input capability to the Liebert APM in both the UPS, 90kVA/kW frame only, or the Bypass Distribution Cabinet (BDC) in either the 45kVA/kW or the 90kVA/kW frame.

The Liebert APM UPS is a SmartAisle™ technology, appropriate for use with the SmartAisle design approach.

The Liebert APM provides continuous, high-quality AC power to business-critical equipment, such as telecommunications and data processing equipment. The Liebert APM supplies power free of the disturbances and variations in voltage and frequency common to utility power, which is subject to brownouts, blackouts, surges and sags.

The Liebert APM utilizes the latest in high-frequency, double-conversion pulse width modulation (PWM) technology and fully digital controls to enhance its reliability and increase the ease of use.

Two frame sizes are available: 45kVA/kW and 90kVA/kW. The 45kVA/kW frame is designed to accept internal batteries; the 90kVA/kW frame does not. The 90kVA frame is, however, designed to accept Internal Transformers and a four-breaker bypass.

1.1Limited Life Components

The Liebert APM UPS has a design life well in excess of 10 years. Well-maintained units can continue to provide economic benefits for 20 years or more. Long-life components are used in the UPS wherever practical and cost-effective. However, due to the currently available component material, manufacturing technology limitations and the general function and use of the component, a few components in your Liebert UPS will have a shorter life cycle and require replacement in less than 10 years.

The following components utilized in your UPS system have a limited life cycle and are specifically exempt from warranty. To prevent a wear-out failure of one of these components affecting your critical load operations, Liebert recommends these components be periodically inspected and replaced before the expected expiration of their life cycle. The expected life of each component listed below is simply an estimate and is not a guarantee. Individual users may have site-specific requirements, maintenance and other environmental conditions that affect the length of the component's useful life cycle.

In most cases, replacement components must exactly match the original component specifications. These replacement components are not readily available from third-party component distributors. For assistance with your specific component specifications, replacement component selection and sourcing, call 1-800-LIEBERT. For customers using Emerson Network Power Liebert Services’ preventive maintenance services, periodic inspection of these components is part of this service, as well as recommending component replacement intervals to customers to avoid unanticipated interruptions in critical load operations.
