INTERCHANGEABILITY & PACKING

All spares supplied under this contract shall be

strictly interchangeable with parts for which they are

intended for replacements . These spares should

include all mounted accessories like components,

boards, add on items, fittings, connectors etc. and be

complete in all respects so that the replacement of the

main items by these spares does not require any

additional items. The vendors must confirm the pin to

pin compatibility of each electrical spare module with

the modules supplied in the original package. All

electronic modules should be preset and/or

preprogrammed for ready use at site. Alternately,

suitable instruction sheet indicating the details of

required PCB jumper position, BCD switches,

settings , EPROM/PROM lis tings etc . should be

packed along with each module. Also a caution mark

sign should be put on all such modules, which needs

presetting/preprogramming before putting them into

service. The spares shall be treated and properly

packed for long term storage of spares under the

climatic conditions prevailing at the site e.g. small

items shall be packed in sealed transparent plasticbags with desiccator packs as necessary. Bidder shall

furnish preservation techniques/procedure for long

term storage along with their despatch document.

IDENTIFICATION

Each Spare shall be clearly marked and labelled on

the outside of the packing with its description. When

more than one spare part is packed in single case, a

general description of the contents shall be shown on

the outside of such case and a detailed list enclosed.

All cases, containers, and other packages must be

suitably marked and numbered for the purpose of

identification.CONTRACT QUANTITIES

12/12

The quantities of mandatory spares shall be specified

in Clauses 5.01.00 to 5.22.00 above. Wherever

quantity has been specified as percentage (%) the

quantity of mandatory spares to be provided by the

Bidder shall be the specified percentage (%) of the

total population required to meet specification

requirements for 2x500 MW units. In case thequantity of mandatory spares so calculated happens to

be a fraction, the same shall be rounded off to next

higher whole number.
