Service
Call for service in case of damages to the machine, for example after penetration of liquids, fall of
objects into or on the machine, if it was exposed to rain or humidity (exceeding the allowed ranged), in
the event of a malfunction, a major decrease in performance or a bump.
Accessories
Use only the accessories specified by the manufacturer. Using accessories of other kind can produce
severe malfunctioning of the machine. The use of unauthorized accessories implies the immediate
cancellation of warranty. Siel shall not be liable for any consequent malfunctioning and for any arising
loss.
Personal safety 1
Siel UPS units are designed and manufactured in order to assure remarkably high MTBF values for the
appliance and for the load supply. Please be aware that the MTBF is a statistical parameter and as such
is subject to factual and conceptual limitations.
Please note that the MTBF refers to a correctly installed and maintained device: it does not consider
conceptual neither factual errors made during plant creation, nor mistakes due to negligence or fraud.
Moreover, the reliability of load supply can be further enhanced by means of appropriate plant
measures, even in presence of abnormal conditions (fraud or accident)
Considering the above, for plants involving hazards for people or featuring “mission critical”
operations, we recommend to carry out an in-depth and validated risk analysis, in order to guarantee
the maximum reliability of load supply and to prove that all possible state-of-the art methods were
used at the time of plant erection (e.g. redundant parallel connection of UPS units, coupled with
system external manual bypass and alternative power supply sources, etc.)
SIEL S.p.A. strongly recommends to contact the technical department for further details.
Personal safety 2
According to their specific function, Safepower-EVO UPS units, are only designed for professional
users and shall not be used by untrained personnel.
Maintenance 1
In order to guarantee the expected life for which the product was designed, respect the maintenance
plan mentioned in the relevant chapter.
Maintenance 2
Maintenance shall always be carried out by SIEL S.p.A, in order to be sure that only new and genuine
spare parts are used and that the machine can be updated in line with any technical development
(according to the respective service contract).
Specifically, any machine in which unauthorized, obsolete or outdated spare parts were used shall be
considered as “modified”, implying all the consequences pointed out in paragraph “Modifications to
the equipment”.
Limitation of use
The UPS is not designed to work as a the single equipment to be used to supply power to life saving
devices. For such applications the integration of an additional UPS is mandatory, with further technical
features designed to deliver a backup system to users in the event of the complete failure of the UPS,
of the second equipment or of plant sections included in the same room of the UPS. (see also “Personal
safety”).
