1.Introduction

1.1Thank you!

Thank you for selecting this uninterruptible power source (UPS). It is designed for many years of reliable, maintenance-freeservice.

Important!

Please read this manual. It provides safety, installation, and operating instructions that will help you get the fullest performance and service life from your UPS. This manual describes the inner workings of the UPS and how they relate to providing superior protection from utility power problems such as blackouts, brownouts, sags, swells, EMI/RFI noise, and surges. The manual includes instructions for obtaining factory service if necessary.

If you have a problem with the UPS, please refer to this manual before calling customer service. The troubleshooting section (section 8) can help with most situations typically encountered when using the UPS.

Please save the packaging materials!

The UPS’s shipping materials are designed with great care to provide protection during shipping. These materials are invaluable if you ever have to return the UPS for service. Damage sustained during transit is not covered under the warranty.

1.2 Radio Frequency Interference

Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.

Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules and the Class A limits for radio noise emissions from digital apparatus set out in the Radio Interference Regulations of the Canadian Department of Communications. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.

Shielded signal cables must be used with this unit to ensure compliance with the Class A FCC limits.

1.3 Theory of Operation

This high-performance,line-interactive,uninterruptible power source (UPS) provides clean, reliable, AC power to computer systems and other electrical equipment — protecting them from power blackouts, brownouts, swells, sags, surges, and interference. It is designed to provide protection for equipment that operates on 208 volts AC, as well as peripheral equipment requiring 120 volts AC.

The UPS requires single phase 208 volts AC input for proper operation. Typically, this is supplied by connecting the UPS to two phases of a three phase 208V delta or 120V wye service.

The primary output is single phase 208 volt AC. An auxiliary 400VA, (3.3 amps), 120 volt AC output is provided to receptacles on the rear panel by an internal isolation transformer with the output neutral grounded.

When the front panel display or the optional software report the amount of load, the load on the 120 VAC output is not reported separately, but it is included in the total load. This means that the 120 VAC load is accounted for when calculations are made to determine the amount of run time remaining.

Note: Any load on the 120 volt output reduces the maximum load that can be powered by the 208 volt output.

Note: The 120 VAC output is provided by an isolation transformer which adds resistance in series with the equipment to be powered. As a result, the 120 VAC output variation due to load (expressed as a percentage of nominal output) will be greater than the 208V output it is powered from. This should not be a problem for most equipment that will be powered. See Section 12 for more information.

Normally, the UPS operates “on-line,”supplying power from theutility input to theload (workstation, server, or other device). Theconverter circuitry is used to maintain an optimal float charge level on thebattery.

When the utility fails, the converter supplies AC power to theload and thedisconnect switch opens. The loads operate normally until shut down or until the battery is exhausted. The UPS automatically transfers the load back to utility power when the line voltage returns to normal.

The UPS also provides surge protection and EMI/RFI filtering, as well asSmart-Boost andSmartTrim, which correct high and low input voltage without drawing power from the battery.Output control uses the UPS’s remote interface to turn the load on or off, without disabling other UPS functions.

1.4 Features

Intelligent Battery Management

The UPS provides visual and audible indications of the battery’s present status including capacity, low battery condition, and replace battery condition.

The UPS exercises the battery during its self-test,and detects a weak battery before it is put into service. The UPS normally performs aself-testat power up and every 14 days.Self-testscan also be conducted manually with the on/test button at any time.

The UPS features user-replaceablebatteries. Batteries can be replaced without having to remove power from the loads or send the UPS in for service.

Computer Interface and Accessory Slot

Advanced monitoring, power management, and customizing functions are available through the computer interface and accessory slot. See section 7 for more information.

2. Safety

CAUTION!

To reduce the risk of electric shock in conditions where load equipment grounding cannot be verified, disconnect the UPS from the AC power outlet before installing a computer interface or accessory slot signal cable. Reconnect the power cord only after all signaling connections are made.

Connect the UPS to a two-pole,three-wiregrounding AC power outlet. The receptacle must be connected to appropriate branch protection (fuse or circuit breaker). Connection to any other type of receptacle may result in a shock hazard and violate local electrical codes.

The UPS has an internal energy source (the battery). The output may be energized when the unit is not connected to an AC power outlet.

To deenergize the outputs of the UPS, first press the Off button for more than one second to switch the UPS off. Next disconnect the UPS from the AC power outlet. To deenergize the UPS completely, disconnect the battery. See section 10.

This UPS’s protective Earth conductor carries the leakage current from the load devices (computer equipment). This UPS generates approximately 1.5 mA of leakage current. To ensure a safe limit of 3.5 mA, limit the total leakage current of the load devices to 2 mA.

Use of this equipment in life support applications where failure of this equipment can reasonably be expected to cause the failure of the life support equipment or to significantly effect its safety or effectiveness is not recommended.
