CAUTION
The instructions in this user manual are intended for a skilled technician (see paragraph 2.2.1)
1.1
Purpose of the manual
The purpose of this manual is to provide the skilled technician with instructions for safely installing the Whad HE Unin-
terruptible Power Supply, also called “UPS” or “equipment” in the rest of the manual, and carry out ordinary maintenance
procedures.
Any adjustments and extraordinary maintenance operations are not dealt with in this manual because they are the sole
preserve of LEGRAND’s Technical Support Service.
The reading of this manual is essential but does not substitute the skill of the technician who must have received ade-
quate preliminary training.
The intended use and configurations envisaged for the equipment and shown in this manual are the only ones allowed
by the Manufacturer.
Any other use or configuration must be previously agreed with the Manufacturer in writing and, in this case, the written
agreement will be attached to the installation and user manual.
This manual also makes reference to laws, directives and standards that the skilled technician is required to be aware of
and consult.
The original text of this publication, drafted in Italian, is the only reference for the resolution of disputes of interpretation
linked to translations into other languages.
1.2
Where and how to keep the manual
This manual must be kept in a safe, dry place and must always be available for consultation exclusively by the skilled
technician.
It is recommended to make a copy of it and file it away.
If information is exchanged with the Manufacturer or the authorised assistance personnel, it is essential to refer to the
equipment’s rating plate data and serial number.
INDICATION
The supplied manuals are an integral part of the equipment and must therefore be kept for their entire lifetime. In case of
need (for example in case of damage that even partially compromise the consultation) the skilled technician is required
to get a new copy exclusively from the Manufacturer, quoting the publication code on the cover.
1.3
Update of the manual
The manual reflects the state of the art when the equipment was put onto the market. The publication conforms with the
directives current on that date. The manual cannot be considered inadequate when new standards come into force or
modifications are made to the equipment.
Any addition to the manual the Manufacturer considers appropriate to send to the users, must be kept together with the
manual of which they will become an integral part.
The updated version of the manual is available on the Internet at http://www.ups.legrand.com
1.4

especially the following:
- always work within the operating limits of the equipment;
