The AMF panel must be designed to ensure trouble free performance and ensure switching over Electrical Load to DG within 15 (fifteen) second from the instant of mains failure. Acoustic Enclosure The DG set should have integrated acoustic enclosure at the manufacturing state itself. High quality acoustic enclosure must be certified as per CPCB-II norms. Base Frame Common iron channel fabricated base frame containing the engine and alternator, mounted on AVM pads and having provision for lifting Hook. Terms & Conditions (i) Rate should be quoted inclusive of all applicable taxes and Duty etc. (ii) All materials, equipments& accessories must conform to relevant IS specifications. The DG Set to be supplied must be from the authorized OEM of the respective Engine Manufacturer.

(iii) Necessary manufacturer's test certificate for Diesel Engine, Alternator etc. Will have to submit in triplicate copy during delivery of the equipment. (iv) Copy of "Type Approval Certificate" and Certificate of "COP" must be produced at the time of delivery issued from competent Authority (As per CPCB-II). (v) Circuit Diagram for AMF Panel must be submitted from the Manufacturer / OEM. (vi) The entire set must be warranted at least 15 months from the date of Delivery / 12 months/ 5000 Hrs from the date of Commissioning whichever is earlier. However Engine & Alternator should be warranted of 2 years / 5000 Hrs, whichever is earlier.During commissioning, the DG set has to be made to run for atleast six hours at a stretch on atleast 75% load at the cost (cost of fuel, operator and technical personnel) of the agency entrusted with the work and the agency will have to provide permanently multi-core control cables as required with allied accessories including laying of the same before commissioning of the DG set. NOTE- If any refurbished material is supplied and installed, penal action will be taken as per existing rules.
