VENTILATION

The genverter normally draws air from the engine room. An
engine room with natural ventilation must have vent openings
of adequate size and location to enable the genverter to
operate without overheating. To allow an ample supply of air
within the temperature limits of the genverter an opening of at
2
least 100 cm 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. Air temperatures above
40°C reduce the engine power by 2% for each 5°C of rise. At
higher temperatures the electric output will be lower. To
minimize these effects the engine room temperature must not
exceed the outside ambient air temperature by more than
15°C.
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 to clear
fumes from the bilge and to circulate fresh air. Air outlets
should be at the top of the engine compartment to evacuate
the hottest air. An engine compartment blower should be used
as an extraction ventilator to remove air from the engine room.
In cases where it is impossible to meet the above mentioned
temperature limit by using engine compartment ventilation,
connections are to be made for an air inlet directly to the
genverter enclosure. With these connections the genverter can
be directly connected to an air duct.
Air inlets should be louvered, where appropriate, to protect the
engine room and to protect the genverter from water spray.

CONNECTIONS

The genverter comes with all supply lines and output cables (i.e.
electric cables, exhaust stub, fuel lines etc.) already connected.
The supply lines are fed through the capsule's front base. The
connections are marked as shown in Figures 2-5.
Refer to Section 5.1 for a graphical overview of installation and
wiring connection requirements.
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 conduits.
ATTENTION!
Before working on the system, read the safety
instructions.
