Conditions Of Use; Introduction - Meta System HF TOP LINE 910 Bedienungsanleitung

Congratulations on your purchase of a Meta System product!
This manual contains information on safety, installation, and operation of the HF TOP LINE
Uninterruptible Power Supply (UPS) produced by Meta System, in both the single and double
cabinet configurations.
Please read this manual carefully before proceeding to install the UPS and follow the
instructions scrupulously.
The HF TOP LINE UPS are designed primarily for civil, industrial, and electro-medical use,
however in the latter case you should ascertain whether there are any particular national
regulations in this regard in your country.
In the event of problems with the UPS, we recommend that you read the manual again before
contacting the service centre. The "Trouble-shooting Guide" can help you resolve most of the
problems that may occur in using the UPS.
Important note
We recommend that you keep the original packing materials, as they may be useful should you
need to transport the UPS for repairs.
Any damage during transport of the UPS caused by poor packing is not covered by the
warranty.

CONDITIONS OF USE

• The UPS has been designed to supply power to data processing equipment. The load applied
must not exceed that indicated on the rear plate of the UPS.
• The ON/OFF button of the UPS does not electrically insulate the internal parts. To insulate the
UPS, disconnect it from the mains outlet.
• Never open the UPS cabinet, as there may be parts on the inside with dangerous voltage even
when the mains plug is disconnected. In any case there are no parts inside the UPS that can
be repaired by the user.
• The front control panel is used for manual operations. Do not press on this panel with sharp or
pointed objects.
• The UPS has been designed to operate in rooms or spaces that are closed, clean, free of
inflammable liquids and corrosive substances, and not excessively humid.

INTRODUCTION

The HF TOP LINE UPS have been designed to guarantee maximum safety and reliability in
supplying power to I.T. systems independently of the condition of the mains electrical supply. The
UPS is based on the combination of "intelligent" control logic governed by a powerful
microprocessor, and modular "on-line" power modules that use high frequency PWM technology
which ensures excellent performance featuring clean, precise output voltage, efficiency,
reliability, and quiet operation.
In addition, the modular redundant structure makes it possible to have a continuous energy
supply, though at reduced power, even in the event of a power module failure, thus offering a
very high level of operating security. Particular attention has been paid to the design of the input
stage which, in addition to the classic filter and line control functions, also handles current
absorption from the mains, keeping it close to that of the ideal sinusoidal wave form. This
eliminates repeated absorption peaks typical of power supplies used in I.T. systems, and takes
the input power factor to values near 1 (in compliance with European regulations).
