INFORMATION

2 POWER
The nameplate gives the nominal maximum load in
kVA = kW calculated with power factor one. When
calculating a load one should always take into
account the power factor or Cos phi of this load. The
power should never exceed the nominal Power in kW
as shown on the nameplate. Power is rated at an
ambient temperature of 104°F (40°C) and a seawater
temperature of 77°F (25°C). For higher temperatures
the generating set has to be derated.
3 VOLTAGE shows the nominal voltage.
This voltage should be within the specified tolerance
at the nominal frequency.
4 FREQUENCY is shown in Hz and is determined by
the speed of the engine (RPM). 60 Hz correlates with
3600 rpm.
5 CURRENT shows the maximum current that is ac-
ceptable at the specified frequency, voltage and po-
wer factor.

SAFETY

2.1.1 General

When correctly installed and used in normal circumstan-
ces this generating set fulfils EC safety regulations. This
generating set could be part of an installation or could be
used in a way that additional regulations of the EC or
other authorities have to be taken into account.
Circumstances could make it also neces-
sary to take additional measures. Be awa-
re of wet conditions and hazardous envi-
ronments caused by explosive gasses etc.

2.1.2 Electrical safety

The voltage of 120 Volt generated by this
generating set is dangerous and if instruc-
tions and procedures are not strictly obser-
ved may result in electrical shock which
will result in severe personal injury or loss
of life.
• Check all wiring at least once a year. Defects,
such as loose connections, burned cables etc.
must be repaired immediately.
6
6 WEIGHT shows the net dry weight (approximately) .
This is without fuel, oil, packing and external instal-
lation equipment.
7 The CE symbol shows that the generating set is build
according to European Community safety regulations.
This includes the regulations regarding the safety of
pleasure craft, machinery, electric safety and electric
magnetic compatibility (EMC) and other relevant
directives.
Safety also relies on the installation, application and cir-
cumstances. See also the remarks in this manual under
SAFETY
Before changing a factory setting you are advised to con-
sult the manufacturer. When the generating set you have
to identify is not new you have to take into account the
possibility that former users changed the settings. Check
the settings (voltage, frequency, rpm) when there is any
doubt.
• Do not work on the electrical system if it is still
connected to a current source. Only allow chan-
ges in your electrical system to be carried out by
qualified electricians.
• Connection and protection must be done in accor-
dance with local standards.
• Using the auto-start/stop (interval) mode the
generator can start
working on the electrical system, the 3 Amp
fuse must be removed from the control panel
and the battery plus cable must be removed
from the battery.
Warning signs indicate parts which could
be live.

2.1.3 Earth insulation failures

According to local regulations and depending on the ap-
plication it is necessary to take measures for protection
against earth insulation failures. In the U.S.A. version
neutral and ground are connected on the alternator. This
requires an insulation protection device as commonly
unexpectedly. When
