Identification plate

All required identification data are on the identification
plate. For location of the identification plate see figure 1
Fig. 1: Identification plate.

6
1 The identity of the generating set is given by the
SERIAL NUMBER.
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 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. The W-SQ20 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 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, 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.
