Incorrect procedures in receiving, storage, transport and handling facilities and in assembly can cause damage to the performance of this equipment. The following instructions should be read and carried out carefully by responsible personnel for the installation and they are valid for assembly of the PBP surge arrester line. This equipment should only be installed and operated by qualified personnel who have been trained and know the procedures and rules determined by the safety standards for use in equipment under electrical conditions. The instructions below are prepared for installation in non-energized electrical systems which were all adopted as safety measures for work in that system. Serious material damage, grievous bodily harm and/or death can be the result of ignoring these instructions. This document is not valid as a guarantee for the product.

Receiving:
•   The products are packed in the factory in order to withstand the possible mechanical
    and climatic effects during transport in agreement with the customer's instructions.
•   To carry out a brief inspection of the material in order to verify occasional damage
    during transportation. Should this occur, please immediately inform the carrier and
    consult the manufacturer about the possible damage caused to the product.
•   When removing the lids or internal spacers of the wooden boxes, take care of the
    sharp edges and perforated material so that they do not perforate or tear the
    packaging.

Storage:
•   This product should be stored in its original packaging, free from direct contact with
    the soil, humid areas and/or pollutants.
•   Please observe the storage instructions contained in the packaging in order to
    guarantee the integrity of the product.

Transport:
•   The transport of this product should be carefully carried out with its packaging until
    the installation point, where only after that, packaging may be removed.
•   Do not transport this product out of its original packaging and in contact with other
    materials that can damage it.
•   Please observe the transport instructions contained in the packaging or
    recommended by the safety team.

Handling:
•   Do not drop and/or knock the equipment, because its internal components are
    made up of rigid and fragile materials. In case this happens, the product may be
    damaged internally or have its operation effected.
•   Do not use cutting or sharp materials to open the packaging, because they can
    damage the equipment and its subsequent operation.

Installation:
•   Before installing this product, please check on the identification plate located in the
    upper part of the surge arrester (fig. 1), if the nominal voltage is appropriate for the
    voltage of the system where it will be installed.
•   The selection of the operation voltage should be made by a technically qualified
    person and should be in accordance with the recommendations from the local
    energy suppliers-. In case there is some discrepancy in this value in relation to the
    one technically indicated, do not install this equipment, because the use and/or
    incorrect installation of this product may cause damage to the user and to the
    installation facilities.

Assembly:
•   Lack of care in the installation of this equipment or the use of bending or traction
    forces above those which are suitable, can damage its polymeric casing or
    insulating base and harm its operation.
•   The maximum bending force of the insulating base should not be higher than 50kgf.
•   If necessary, in the assembly of the NEMA brackets fixing, the crosspiece should be
    made in agreement with the recommendations of the local electricity supplier or
    from the manufacturer, as shown in the two assemblies in fig. 2.
•   If there is non-alignment in the crosspiece of the product after its installation, this
    non-alignment must be corrected by the straightening of the "L" base in the NEMA
    brackets. Do not try to force the insulating base in order to correct this
    non-alignment, because it may break.
•   If there is no adequate control of the tightening, a risk of damage may occur to the
    equipment. The torques to be applied to the screws of the insulating base should
    be fixed to the NEMA brackets and to the terminals phase and earth, shown in fig. 2,
    which must not be higher than 2.4kgf.

Electrical connections:
•   The line terminals and phase consist of bi-metallic materials which are designed
    from flexible connection cables from 6 to 35mm2.
•   The use of rigid materials or gauges stronger than the one indicated in the
    connections can mechanically affect the terminals, as well as rupture the automatic
    disconnector.
•   The best performance of this equipment is related to the shortest length of
    connection cables and with a good connection to the earth through a low earth
    resistance.
•   Be sure that the connections are firmly connected before the re-energizing of the
    system.

Accessories:
•   In case the surge arrester is accompanied by an optional insulating cover for the
    terminal phase for the protection against accidental contact or of small wild animals,
    the surge arrester should only be installed after the connection of the cable phase.
•   No necessary special tool is included with the product for the assembly of the
    equipment.
