Key Installations

• Proper space should be there for placement and opening of doors of the Silent DG set.
• There should be atleast 1.5 meter free space around the DG set for proper operation and maintenance.
• There should be cross ventilation of air to ensure proper cooling of DG set. Exhaust gases and hot air discharge should not re-circulate inside the acoustic enclosure (canopy).
• There should be no restriction for fresh air suction and hot air discharge. If 2 DG sets are installed at the site, ensure that hot air outlet of the one DG set does not become the fresh air intake of the 2nd DG set.
• A low height shelter for the Silent DG Set should be avoided. It should not obstruct the hot air outlet.
• It is preferable to install the DG set in an open area. No shade (roof) is required over it. However, if the AMF Panel is outside the Acoustic Enclosure, then a shelter is recommended for the Panel.
• For Roof Top Installation, ensure that the civil structure is capable to bear the static and dynamic load of DG set. The load of the Silent DG set should be borne by Columns and Beams of the building.
• Proper space should be there for Earthing.
• If there are no space constraints, the DG set should be placed near the distribution panel.
• The DG set should be located away from polluted surroundings such as corrosive fumes, cement dust, fibres, cotton and toxic chemicals to avoid overheating of the D.G. Set.
• The Foundation should be water leveled and atleast 3” above the Ground Level.
• The Length and width of the Foundation should be atleast 200mm to 400 mm more than that of the DG set size.
• Please refer to the foundation drawing attached herewith.
• A rigid foundation ensures the least vibration. Sand Filling should be there around the foundation. Rubber matting can also be used over the foundation to minimize the vibration effect and noise leakage.
• Please refer to the dimension of DG set for deciding the foundation length, width and depth.

• An Earthing system is required for the protection of equipment and human being, as per Indian electricity Rules 1956.
• Separate earth should be used for body and neutral earthing.
• 4 Nos. earthing pits are required for 3 phase DG set, 2 each for neutral & body
• 2 Nos. earthing pits are required for single phase DG set, 1 each for neutral & body
• The min. distance between 2 earthing pits should be 2.0 meters.
• An earth pit cover should be provided.
• A watering pipe of 19mm with a funnel should be provided for each pit, wherever depth of the earthing pit is not at water level.
• Earthing  system  should  be  checked  with  meagre  and  maximum  1.0 om resistance should be ensured.
• The earthing plate/pipe and strip size should be selected as per the rating of the DG set.

• A supply and return fuel pipe is required in each DG set.
• SDGs up to 200 KVA are provided with fuel tanks inside the acoustic enclosure.
• Above 200 KVA, the fuel tank is outside the acoustic enclosure.
• For fuel tank inside the enclosure, fuel piping is done by the manufacturer/supplier.
• However, for Fuel Tank outside the enclosure, fuel piping is to be done by the customer.
• Size of the fuel piping should be 12mm upto 250 KVA DG set.
• Class M.S. pipe (19 mm -25mm I.D.) is recommended For fuel piping above 250 KVA DG sets.
• MS pipe should be used with proper welded joints.
• Stop valve and flange should be used at supply line to engine near fuel tank (for Fuel Tank mounted outside).

PRECAUTIONS TO BE TAKEN FOR FUEL PIPING AND FUEL SYSTEM.

• Never use GI pipes in fuel piping of DG set.
• Joints should be welded and never threaded.
• Pipe should be above ground level with proper MS support.
• All joints should be tested for any seepage or leakage.
• For 320 KVA and above DG sets, Fuel Tank height should be such that lowest level of Fuel Tank is above Diesel pre-filter height.

• It has been our experience that most electrical failures are caused by overheating due to loose thimbling or undersize cables.
• Please use cable of correct size to carry full load current and thimble of correct size for cable termination.
• At no time, loose wires should be tightened on to terminal/busher with bolts.
• Crimping should be done with proper crimping tool.

• If dry battery is supplied along with the DG set then initial charging of the battery is required.
• Please get initial charging of the battery done) 520 an authorized service dealer of the battery manufacturer.
• The initial charging process is of 72 hours.
• Specific gravity of acid inside the battery should be 1.23 to 1.28 kg/ltr.

• If charged battery has been provided along with the DG set, and the DG set is not in use then ensure that at positive terminal battery lead is not connected. It should be connected at the time of the commissioning of the DG set.
• Charged battery may be used for commissioning of DG set within 15-20 days, else re-charging of charged battery is required.
• Always connect the battery with the proper battery charger. The battery should be connected to the battery charger, which is connected with 230V AC supply.
• The Battery charger is provided with an AMF Panel (Auto Mains Failure Panel) under the standard scope of supply. 230V AC supply is essential for battery charger operation.

• Do not charge the battery at a wet a place.
• Flame, Candle and matchbox should not be used near charged battery. Use hand gloves while handling the charged battery.
• Electrolyte level should be below the neck
• Always switch off the charger first before disconnecting the battery from the DG set.
• Never put tools etc. on the battery.
