MODEL
Fig. 1: Location of the identification plate.
1 The identity of the generating set is given by the
SERIAL NUMBER.
Example:
When this number is available the manufacturer can
trace the specifications of the generating set. On the
identification plate are also some basic features of the
set:
2 POWER
The identification plate 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 identification plate.
Power is rated at an ambient temperature of 25ºC.
For higher temperatures the generating set has to be
derated. To drive the radiator fan (230 V or 230/400V
fan) output could be taken from power generated by
the genset. In that case net power will be less than
specified on the identification plate
3
VOLTAGE shows the nominal voltage.
This voltage should be within the specified tolerance
at the nominal frequency and a balanced load. The
Whisper 12 ULTRA Three Phase can be connected
as 3-phase 230/400Volt (STAR) or as 3-phase
230Volt (DELTA). The alternator is not designed and
rated for single phase applications. For single phase
applications Mastervolt offers another model that has
dedicated windings. The nameplate indicates the
connection as made in the factory; BE AWARE THAT
THE CONNECTIONS COULD BE RECONNECTED
BY FORMER USERS
4 FREQUENCY is shown in Hz and is determined by
the speed of the engine (RPM). 50 Hz correlates with
1500 rpm. Mastervolt offers generators for 1800 rpm
60 Hz applications as well. When necessary a
Whisper 12 Three Phase model can be reconnected
and set for 60 Hz applications. A 60 Hz special
manual is available upon request.
5 CURRENT shows the maximum current that is
acceptable at the specified frequency, voltage and
power factor. 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, cooling liquid, 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 safety of machinery, electric
safety and electric magnetic compatibility (EMC) and
other relevant directives.
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 may have changed the
settings. Check the settings (voltage, frequency, rpm)
when there is any doubt
