CAUTION: The UPS and connected load total earth leakage current must not exceed 3.5 milliamperes. If the connected load earth leakage current is likely to exceed 2.5 milliamperes or you are unsure, then convert the input lead attachment to either a fixed wiring installation or an industrial plug/socket (e.g. CEE 17 connector). This task should be carried out by a competent electrical engineer who is conversant with local electrical codes/regulations.

9.The UPS output supply sockets may be electrically live whenever the input power lead is plugged into the mains supply socket. Turning the UPS OFF does not electrically isolate the internal parts. To isolate the UPS, turn the UPS OFF then isolate it from the mains supply.

10.When installing the UPS or making input and output connections, comply with relevant safety standards (e.g. IEC950, VDE0805, EN50091-1).

11.This equipment complies with the requirements of the EMC Directive

89/336/EEC and the published technical standards. Continued compliance requires installation in accordance with these instructions and the use of manufacturer approved accessories with output cables not exceeding 10 metres (30 ft.) in length. Use a shielded cable for the external communications interface.

12.Operate UPS only from a properly earthed, 50 Hz or 60 Hz, 220-240 VAC mains supply. Models are available for 100-127 VAC supply voltages.

13.Route power supply leads so they are not walked on or pinched.

14.Never block or insert any object into the ventilation holes or other openings. Maintain a minimum clearance of 100 mm (4 inches) all around the UPS for proper air flow and cooling.

15.Operate the UPS in an indoor environment only, with an ambient temperature range of 0° C to +40° C (32° F to +104° F). Install it in a clean environment, free from moisture, flammable liquids, gasses, or corrosive substances.

16.Storing magnetic media on top of the UPS may result in data loss or corruption.

17.Turn the UPS off and unplug the UPS before cleaning. Use only a soft cloth, never liquid or aerosol cleaners.

18.This equipment can be operated by individuals without previous training.

INTRODUCTION & SYSTEM DESCRIPTION

Congratulations on your choice of the Liebert PowerSure™ Interactive Uninterruptible Power System (UPS). It provides conditioned power to microcomputers and other sensitive electronic equipment.

Upon generation, AC power is clean and stable. However, during transmission it may be subject to voltage sags, spikes, or complete power failure which may interrupt computer operations, cause data loss, or even damage equipment. The PowerSure™ Interactive protects equipment from these disturbances.

The PowerSure™ Interactive comes in nominal power ratings of 700, 1000, 1400, or 2200 VA. Complete specifications appear near the end of this section.

The PowerSure™ Interactive is a compact, “line interactive” UPS. A “line interactive” UPS continuously conditions and regulates its output voltage, whether the mains power is present or not. It supplies connected equipment with clean sinewave power, to simulate as much as possible, the power generated by the mains. Sensitive electronic equipment operates best from sinewave power.

For ease of use, the PowerSure™ Interactive contains a light emitting diode (LED) bar display to indicate either “load percentage” or “battery capacity” depending upon the mode of operation. It also provides self diagnostics, a combination alarm silence/battery test button, and two levels of alarms when the unit is operating on battery.

The PowerSure™ Interactive has an interface port for communications between the UPS and a LAN server or other computer system. This port provides detailed operating information including voltages, currents, and alarm status to the host system when used in conjunction with Liebert SiteNet® software. SiteNet® software can also remotely control UPS operation.
