GeneralIntroductionIntroductionOkken is a switchboard made up of a number of modular sections. Such a design facilitates transportation,installation and maintenance.The horizontal busbars are connected between sections by splicing.Prior to shipping, every Okken switchboard has been submittedto the 3 routine tests, as per IEC 60439-1 (wiring and electrical working, protective measures and insulation) and inspected visually, mechanically and electrically by a trained technician of the Quality Inspection department.Safety recommendationsCorrect operation of Okken switchboards requires that handling,installation and operation be carried out exclusively by qualifiedpersonnel: ❑ qualified to work near live equipment❑ trained to all applicable safety practices.During the installation and connecting operations, theswitchboard must be de-energised so as not to exposepersonnel to electric shock hazards.Failure to comply with these instructions and with thoserecalled in this guide may result in very serious or evenfatal accidents of operators or in damage to the switchboard.5OkkenSchneider Electric
Equipment receivingPackingGeneralPackingSome precautions must be taken when receiving the switchboard:❑ on receipt of the equipment and before handling it, checkthat the cases and packing materials used for transportationhave not been damaged and that all items on the packing listhave been effectively delivered❑ even if the packing appears to be in good condition, donot hesitate to unpack the equipment in the presence of anauthorised transport agent❑ check consignment contents and weight. Thoroughly checkthe equipment to make sure that no damage or shocks haveoccurred which may impair insulation or operation❑ if necessary, check that the information given on theswitchboard nameplate, located on the incoming section,conforms to that given on the delivery slip❑ in case of damage or missing parts, inform the transportagent by registered mail.❑ After this inspection, put back the plastic protection cover.The Okken switchboards are normally dispatched column bycolumn, or in sections of 2 juxtaposed columns.Exceptionally, they may be made of sections of 3 columns, inthe case of coupling with 2 incomer columns for example.Each parcel is identified by marking giving:❑ the project number❑ the weight❑ the packing (parcel number and number of parcels)❑ the position of the centre of gravity❑ the storage and handling instructions.Standard packingStandard packingThe column(s) are protected by a plastic cover in a crate. Thelower ventilation grids are delivered separately. They are notmounted so as to allow handling of the column by the bottom.In the same way, the withdrawable devices >= 3200A areusually packed separately.Sea packingThe column(s) are protected by a heat-welded covercontaining desiccant bags and are installed in a ventilated wooden or plywood crate.As a rule the sea crates do not weigh more than 5 tons.Sea packing6 Okken Schneider Electric
