INFORMATION
2.1.3 Earth insulation failures
According to local regulations and depending on the ap-
plication it is necessary to take measures for protection
against earth insulation failures. In the U.S.A. version
neutral and ground are connected on the alternator. This
requires an insulation protection device as commonly
used in the U.S.A. This installation is beyond the
influence of Mastervolt and Mastervolt cannot held
responsible for any consequence as a result of the
installation.
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 Masterswitch.
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 contains carbon monoxide and are extremely
dangerous. Carbon monoxide (CO) is an invisible
odorless 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.
2.1.5 Operation
External moving parts like fans and V-belts are covered
by the canopy and therefore the Whisper 20 ULTRA is
very safe, when the canopy is closed
Never the less take note of the signs on
the generating set which shows symbols in
a triangle indicating danger.
•
When service has to be executed while the
engine is running, be aware of moving parts like
V-belts.
•
The generating set should be operated by authori-
sed personnel only.
•
Be aware of hot parts and specially parts of the
exhaust system.
•
If the generating set is unsafe, fit danger notices
and disconnect the battery positive (+) lead so
that it cannot be started until the condition is cor-
rected.
•
Do not attempt to operate the generating set with
a known unsafe condition. Disconnect the battery
positive (+) lead prior to attempting any repairs or
cleaning inside the enclosure.
•
Always consult the manual before executing
maintenance.
•
Do not change the settings without consulting the
manufacturer. Keep record of changing of the set-
tings in this manual.
2.1.6 Fire and explosion
Fuels can be flammable. Proper handling
limits the risk of fire and explosion.
•
Avoid refilling the fuel tank while the engine is
running. When oil or fuel is leaking do not use the
generating set.
•
Do not run the engine close to explosives or
gasses.
•
Hydrogen gas generated by charging batteries is
explosive. Take measures for proper ventilation.
Do not smoke or allow sparks, flames, or other
sources of ignition around batteries.
•
Keep a fire extinguisher on hand.
•
Poor electrical connections or using wiring which
is not suited for the rated currents can cause
overheating and possibly fire.
2.1.7
Chemicals
•
Fuels, oils, coolants, and battery electrolyte can
be hazardous to personnel if not treated properly.
Do not swallow or have skin contact with these
liquids. Do not wear clothing that has been conta-
minated by fuel or lubricating oil.
•
Gaskets may be manufactured from asbestos.
Particles of this material should not be inhaled as
this may result in fatal diseases.
•
On no account allow any unprotected skin to
come into contact with the injector spray as the
fuel may enter the blood stream with fatal results.
