Installation Recommendations
Preliminary design
Enclosure placement / Enclosure room
A. Ensure sufficient lighting / illumination at the
installation space.
B. Provide suitable , safe access / staging to elevated
items.
C. Provide auxiliary AC supply together with the
associated AC distribution panel and may be with
motor control unit (MCC) where applicable.
D. Standard tool kit should be available easily and
quickly. It should be protected from corrosion and
stored in a dry place.
E. If spares are supplied alongwith the equipment, they
should be protected from corrosion and stored in a
dry place.
F. In case of multiple enclosures provide minimum 2
meters or sufficient clearance to open adjacent doors
simultaneously of two enclosures.
G. While making the layout, provision should be made
for :
I. Cables
II. Fuel lines
III. Breather vent
IV. Coolant / lube oil drain
V. Oil storage
VI. Spares storage
H. Normally, all entry / exit provisions of above are
considered in enclosure design. Try to avoid additions.
If it is required to have additional entry / exit
provisions, ensure for proper sealing of noise,
temperature and entry/exit of foreign particles.
I. Access and clearance
i. Enough opening / shutters should be provided
so that entry and placement of the enclosure is
easily possible.
ii. Generator sets will require access for service to
both sides of the engine as well as the control/
alternator end of the machine. Local electrical
codes may require specific working space for
electrical equipment. Allow for working space equal
to the width of the genset on both sides and rear.
Also ensure sufficient overhead clearances are
provided.
J. Please refer table for typical acoustic enclosure sizes.
K. Future expansion plans should be considered while
deciding total area.
L. The generator room / area around enclosure should
not be used for storage purposes.
M.Avoid installing the enclosure beside heat generating
equipment, or directly below water or steam pipes or
in the vicinity of corrosive substances or vapours,
metal particles and dust.
