CAUTION!

When medium-voltage 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 service 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 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 warranty, under any jurisdiction, including 

loss of income, stoppages and costs resulting from repair or replacement of parts.

Warranty

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.

In view of the constant evolution in standards and design, the characteristics of the elements contained in this manual are subject to change without
