Adhere to all warnings on the unit and in this manual. Follow all operating and user instructions. Individuals must fully understand this equipment to install and operate it.

It is not intended for use with life support or other designated critical devices. Maximum load must not exceed that shown on the Liebert GXT2-PP20KRT208 rating label. This parallel POD is designed for use on a properly grounded (earthed), 100/200, 110/220, 115/230, 120/208, 120/240 or

127/220 VAC, 50Hz or 60Hz supply. Installation instructions and warning notices are found in this manual.

This Liebert parallel POD is only for use with a four-wire input: L1, L2, N, G.

This Liebert parallel POD must NOT be used with a three-wire, single-phase utility source: L1, N, G.

ELECTROMAGNETIC COMPATIBILITY—The Liebert GXT2-PP20KRT208 complies with the limits for a Class A digital device pursuant to Part 15 of FCC rules. Operation is subject to these con- ditions:

•This device may not be permitted to cause harmful interference.

•This device must accept any interference received, including interference that may cause unde- sired operation. Operating this device in a residential area is likely to cause harmful interference that users must correct at their own expense.

Operate the parallel POD only in an indoor environment in an ambient temperature range of 32°F to 104°F (0°C to 40°C). Install it in a clean environment, free from conductive contaminants, moisture, flammable liquids, gases and corrosive substances.

This parallel POD contains no user serviceable parts. Refer all faults to your local dealer, Liebert rep- resentative or the Emerson Network Power Liebert Worldwide Support Group.

Never block or insert any object into the ventilation holes or other openings of a UPS or this parallel POD.

Do NOT connect equipment that could overload the parallel POD or demand half-wave rectification from the parallel POD, for example: electric drills, vacuum cleaners, laser printers, hair dryers or any other appliance using half-wave rectification.

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

Turn the parallel POD and connected UPSs Off and isolate the paralleling system before cleaning; use only a soft cloth, never liquid or aerosol cleaners.
