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.
DANGER
Warning signs draw attention to special
warnings, instructions or procedures which, if
not strictly observed, 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 environments caused by explosive gases etc.
2.1.2

Electrical 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
connected to a current source. Only allow changes
in your electrical 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 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
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.
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).
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,
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. See
the installation manual.
INFORMATION
nausea or death.
