The instructions in this manual are intended for a SKILLED TECHNICIAN (paragraph 2.2.1).
1.1 Purpose of the manual
The purpose of this manual is to provide the skilled technician (see paragraph 2.2.1) with instructions for safely installing
the TRIMOD HE unit, also called "UPS" or "equipment" in the rest of the manual, and carry out ordinary maintenance
procedures.
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 adequate
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 manuals.
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.
