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.
SELECTION OF SITE
1
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.

FOUNDATION DETAILS AND GUIDELINES
A. Ground base Foundation (RCC/PCC)
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.
Note: Please ensure that the foundation should not be made over any
basement, water tank or Sewer Line.
B. Roof Top Foundation
The weight of Silent DG set should be on Column and Beam through
proper foundation.
The RCC foundation should be on the Beam or supported on two
Beams.
ISMC Channel or MS “I” Section may also be used to cater the load of the
DG set with the canopy. Load of ISMC Channel or MS “I” Section should
be on the column of the building.
M.S. Sheet is to be provided at the bottom of the base frame of the Silent
DG set for roof top installation.

Check the DC supply control MCBs F10 and F11 for 3 phase Supply. These
should be in ON position.
Check the battery voltage at terminal 1 and 2 in the AMF Panel. It should be at or
above 24V/12V.
Check all control wires at control terminals in AMF Panel.
Check Battery terminals. They should be properly tightened and should not be
corroded.
Check LLOP signal at AMF Panel control terminal No. 8, up to 125 KVA It should
be properly connected on engine terminal.
It there is rattling should that the starter is engaged but it slips or cranks slowly.
The battery connection may be loose or corroded. Check and correct te

Engine starts but there is no Voltage from the control Panel
Check that the HRC fuses/MCB below the alternator contactor are O. K.
Check that the setting at the Alt Voltage Monitor is not too high, set it to 360 V
and try.
Check the overload Relay if it is tripped and press the reset lever.
The Main supply is restored, but the load does not transfer.
Check the control MCBs at F4, F6. It should be in 'ON' position.
Check if all three phases (RY, YB and BR) of Mains supply are available.
These can be checked through selector switch and voltmeter provided on AMF
Panel. All three phases should be available and voltage should be more that
the setting of mains voltage monitor or AMF Relay.
If required, lower the voltage setting of mains voltage monitor and differential
setting or setting in AMF relays. Increase the voltage setting gradually if Mains
Voltage is not acceptable on load equipment.
