2 INFORMATION
2.1 SAFETY
2.1.1 General
When correctly installed and used in normal
circumstances 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 necessary
to take additional measures. Be aware of wet
conditions and hazardous environments
caused by explosive gases etc
2.1.2
Electrical safety
The voltage of 230 Volt 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
connected to a current source. Only allow
changes in your electrical system to be carried
out by qualified electricians.
•
Connection and protection must be done in
accordance with local standards.
•
Using
event based commands
the generator can
start unexpectedly. When working on the
electrical system, the 30 Amp fuse must be
removed from the Digital Diesel 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
application it could be necessary to take measures for
protection against earth insulation failures.
In the standard delivery “neutral” and “ground” are not
connected. 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. (Refer to the electrical diagram, page 15)
In all situations the transfer switches between
shore, inverter and generator should switch
both neutral and L1. Of course this is the case
when using a Mastervolt Mass Systemswitch.
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 Lloyds 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.
2.1.4 Installation
Whisper generating sets are not self contained and have
to be properly installed in enclosed areas such as a
machine room.
Installation includes measures to be taken to
outlet exhaust fumes which contain carbon
monoxide and are extremely dangerous.
Carbon monoxide (CO) is an invisible odourless gas.
Inhalation produces headache, nausea or death.
Installation includes measures for proper ventilation, safe
electric connections, safe installation of the starting
battery, proper fitting of the cooling system and fuel pipes
etc. Refer to the installation manual.
