Introduction

Thank you for selecting an MGE UPS SYSTEMS product to protect your equipment.

The Comet EX RT range has been designed with the utmost care.
We recommend that you take the time to read this manual to take full advantage of the many features of your UPS.

Warning: this is a class A UPS product. In a domestic environment, this product may cause radio interference, in which
case, the user may be required to take additional measures.
If the device must be installed in overvoltage category III or IV environments, additional upstream overvoltage protection
must be provided for.

To discover the entire range of MGE UPS SYSTEMS products and the options available for the Comet EX RT range,
we invite you to visit our web site at www.mgeups.com or contact your MGE UPS SYSTEMS representative.

Environmental protection

MGE UPS SYSTEMS cares about the environmental impact of its products and has therefore implemented an eco-design
process for the entire life cycle of the Comet EX RT product: design, usage and recycling.
