6 M-SQ PRO 15/18 kVA
Marine Diesel Generator
3
VOLTAGE. This shows the nominal voltage.
This voltage should be within the specified tolerance
at the nominal frequency. The M-SQ-Pro15/18 can be
connected for different voltages in single phase or tri
phase. The nameplate indicates the connection as made
in the factory.
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 pow-
er 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, regard-
ing electric safety and electric magnetic compatibility
(EMC).
Safety also relies on the installation, application and circumstanc-
es. 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, fre-
quency, rpm) when there is any doubt.
2 INFORMATION
2.1 Safety
2.1.1 General
When correctly installed and used in normal circumstances this
generating set fulfills 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.
DANGER
Warning signs draw attention to special warnings,
instructions or procedures which, if not strictly ob-
served, may result in electrical shock which will result
in severe personal injury or loss of life.
Circumstances could make it also necessary to take additional
measures. Be aware of wet conditions and hazardous environ-
ments caused by explosive gases etc.
2.1.2 Elelctrical safety
This warning sign indicates parts which could be live.
The voltage of 230V or 230V/400V generated by this
generating set is dangerous and if instructions and
procedures are not strictly observed 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.
•
Do not work on the electrical system if it is still connect-
ed to a current source. Only allow changes in your elec-
trical system to be carried out by qualified electricians.
•
Using the auto-start/stop (interval) mode the generator
can start unexpectedly. When working on the electrical
system, the 3 Amp Digital Diesel Control fuse must be
removed from the control panel and the battery plus
cable must be removed from the battery.
•
Connection and protection must be done in accordance
with local standards.
2.1.3 Earth insulation failures
According to local regulations and depending on the application
it could be necessary to take measures for protection against
earth insulation failures.
In the standard delivery “neutral” and “ground” are not connect-
ed. To make a connection between “neutral” and “ground” could
be necessary as part of a specific insulation failure protection
system.
Small pleasure craft in Europe is submitted to The Recreational
Craft Directive 94/25/EC. The guidelines of this directive refer to
(ISO 13297).
When the installation complies with this standard the “neutral”
and “ground” should be connected on the generating set.
Be aware that insulation protection systems can be different
for different applications and even within the ship there could
be different standards for different spaces. We did refer to the
Recreational Craft Directive that applies to pleasure craft up to 24
m of length. Sometimes one has to comply with other standards
such as the rules of certification societies like Lloyd’s Register of
Shipping or Veritas, regulations for the protection of personal,
building legislation, etc. It is of the greatest importance to have
expert advice on this issue.
In all situations the transfer switches between shore,
inverter and generator should switch both neutral (N)
and all phase lines (L1, L2 and L3).
