When two batteries are used in series to provide
a 24 Volt supply system, never take off 12 Volt
(starting) power from one of these batteries. This
will result in severe damage to both batteries
within a short time.
Disconnect the battery leads if electrical welding is to be carried
out, otherwise damage will be caused to the diodes of the
alternator.
As explosive hydrogen gases may be discharged
during charging, the battery should be located in
a well-ventilated space. Ensure that the supplied
battery cable connectors are properly fitted.
Never remove these during or shortly after
charging, as sparking may occur, igniting the
hydrogen gases.
3.8
ALTERNATING CURRENT
The electric power supplied by the genverter is
of a high voltage and dangerous to people.
Before working on the system read the sections
on safety in the users manual.
Be aware that people are not used to have AC
available on a vehicle. Put warning signs on wall
sockets and on junction boxes. Instruct non-
regular users of the vehicle. Warn maintenance
personnel of garages that do service on the
vehicle.
Generators used on vehicles that are operated in
a hazardous environment often have to fulfil
special regulations and additional measures have
to be taken accordingly.
These genverters are designed to generate power for both AC
and DC installations, depending on the type of WhisperPower
PowerCube or Power Module installed with the genverter. Be
sure that all electrical installations (including all safety systems)
comply with all regulations required by the local authorities. All
electrical safety/shutdown and circuit breaking systems have to
be installed onboard as the genverter itself cannot be equipped
with such equipment for every possible variation.
The vehicle’s power supply system should be suitable and safe
for the voltages applied and the power that will be generated.
Special attention has to be paid on dividing the system in
branches which are fused individually.
It is absolutely essential that each and every circuit in the
electrical system be properly installed by a qualified electrician.
3.9
FUSE
It is the installer's responsibility to protect the live wires
between the genverter and the PMG/DC PowerCube. Check the
electrical information on the identification plate in order to
calculate the right fuse size.
3.10
GROUNDING
The AC alternator windings are not grounded.
The housing of the alternator and all other metal parts are
grounded. The position of the earth lug is shown in Figure 6.
The electric installation in the vehicle possibly needs to be
protected against insulation failures. Methods of protection are
subject to rules that may differ depending on the use of the
vehicle and local standards. Experts in this field should be
consulted.
3.11
CABLE
For the power cable we recommend the use of 3 wire single
phase oil resistant cable with a sufficient cross sectional area.
For long cables it is recommended to apply cables with a larger
cross section (refer to ISO 13297 annex A).
