CAUTION!
When MV equipment is operating, certain components are live, other parts may be in movement and some may reach high
temperatures. Therefore, the use of this equipment poses electrical, mechanical and thermal risks.
In order to ensure an acceptable level of protection for people and property, and in compliance with applicable environmental
recommendations, Ormazabal designs and manufactures its products according to the principle of integrated safety, based on
the following criteria:
Elimination of hazards wherever possible.
Where elimination of hazards is neither technically nor economically feasible, appropriate protection functions are
incorporated in the equipment.
Communication about remaining risks to facilitate the design of operating procedures which prevent such risks,
training for the personnel in charge of the equipment, and the use of suitable personal protection equipment.
Use of recyclable materials and establishment of procedures for the disposal of equipment and components so
that once the end of their useful lives is reached, they are duly processed in accordance, as far as possible, with
the environmental restrictions established by the competent authorities.
Consequently, the equipment to which the present manual refers complies with the requirements of section 11.2 of the
forthcoming IEC standard 62271-1. It must therefore only be operated by appropriately qualified and supervised personnel, in
accordance with the requirements of standard EN 50110-1 on the safety of electrical installations and standard EN 50110-2 on
activities in or near electrical installations. Personnel must be fully familiar with the instructions and warnings contained in this
manual and in other recommendations of a more general nature which are applicable to the situation according to current
legislation.
The above must be carefully observed, as the correct and safe operation of this equipment depends not only on its design but
also on general circumstances which are in general beyond the control and responsibility of the manufacturer. More specifically:
The equipment must be handled and transported appropriately from the factory to the place of installation.
All intermediate storage should occur in conditions which do not alter or damage the characteristics of the
equipment or its essential components.
Service conditions must be compatible with the equipment rating.
The equipment must be operated strictly in accordance with the instructions given in the manual, and the
applicable operating and safety principles must be clearly understood.
Maintenance should be performed properly, taking into account the actual service and environmental conditions
in the place of installation.
The manufacturer declines all liability for any significant indirect damages resulting from violation of the guarantee, under any
jurisdiction, including loss of income, stoppages and costs resulting from repair or replacement of parts.
Guarantee
The manufacturer guarantees this product against any defect in materials and operation during the contractual period. In the
event that defects are detected, the manufacturer may opt either to repair or replace the equipment. Improper handling of this
equipment and its repair by the user shall constitute a violation of the guarantee.
Registered Trademarks and Copyrights
All registered trademarks cited in this document are the property of their respective owners. The intellectual property of this
manual belongs to the manufacturer.
In view of the constant evolution in standards and design, the characteristics of the elements contained in this manual are
subject to change without prior notification.
These characteristics, as well as the availability of components, are subject to confirmation by Ormazabal’s Technical -
Commercial Department.
