VENTILATION
The generating set normally draws air from the engine compart-
ment. Engine compartment with natural ventilation must have
vent openings of adequate size and location to enable the gener-
ating set to operate without overheating. To allow Sufficient air
within the temperature limits of the generating set an opening of
at least 100 cm2 is required.
A "sealed" engine compartment must have a good extraction
ventilator to maintain reasonable ambient temperatures. High
temperature of intake air reduces engine performance and
increases engine coolant temperatures. The rated power of
the generator is measured at an ambient temperature of 25°C,
each temperature increase of 5°C reduces the engine power by
about 2%. In order to minimize these effects to the extent that
the operator can influence them, the temperature of the engine
compartment must not exceed the temperature of the outside
air by more than 15ºC.
Apply a combination of ventilators, blowers and air intake ducting
to meet the temperature limit. The air inlet ducts should run to
the bottom of the engine compartment and to circulate fresh air.
Air outlets should be at the top of the engine compartment to
remove the hottest air. An engine compartment blower should
be used as an extraction ventilator to remove air from the engine
room.

CONNECTIONS
The generating set comes with all supply lines and output cables
(i.e. electric cables, coolant connections, exhaust, fuel lines etc.)
already connected to the engine and generator. The supply lines
are fed through the capsule's front base. The connections are
marked as shown in figures 7 till 10.
All electrical connections, cable types and sizes must comply with
the appropriate national regulations. Supplied cables are rated
for ambient temperatures up to 70°C. If the cables are required
to meet higher temperature requirements, they must be run
through insulations.
ATTENTION!
Before working (installation) on the system read the
section safety instructions.
