Fig. 2: Location identification plate.
2 POWER
The nameplate gives the nominal maximum continues
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 as
shown on the nameplate. Power is rated at an
ambient temperature of 40°C and a seawater
temperature of 25ºC. For higher temperatures the
generating set has to be de-rated.
3
VOLTAGE. This shows the nominal voltage.
This voltage should be within the specified tolerance
at the nominal frequency. The M-SQ20 / 25 can be
connected for different voltages in single phase or tri
phase. The nameplate indicates the connection as
made in the factory; BE AWARE THAT THE
CONNECTIONS COULD BE RECONNECTED BY
FORMER USERS
4 FREQUENCY. This is shown in Hz and is determined
by the speed of the engine (RPM). 50 Hz correlates
with 1500 rpm.
5 CURRENT. This shows the maximum current that is
acceptable at the specified frequency, voltage and
power factor. When connected in tri phase the
indicated current is the current between two phases
that can be taken off three times.
6 WEIGHT shows the net dry weight (approximately) in
kg. This is without fuel, oil, packing and external
installation equipment
7 CE MARKING.. 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,
safety of machinery, regarding electric safety and
electric magnetic compatibility (EMC).
Safety also relies on the installation, application and
circumstances. See also the remarks in this manual under
SAFETY.
Before changing a factory setting you are advised to
consult the manufacturer. When the generating set you
have to identify is not new you have to take into account
the possibility that former users did change the settings.
Check the settings (voltage, frequency, rpm) when there is
any doubt.
