can be used to charge the starter battery only, such as the
WBC Handy 20 or 70 included in the battery installation
kits listed in 3.4.

12V OR 24V DC TO DRIVE THE FAN
When applying 12 or 24 VDC to drive the fan of the
radiators the fan should be wired with minimum 4mm²
cable according to the wiring diagram. The negative return
wire should be of the same diameter. The return current
should never be lead over the chassis.
The consumption of power by the 12VDC powered fan
makes it necessary to install an additional 30 Amps battery
charger to prevent the starter battery to be drained. A
much larger battery (170Ah at least) is required. The
battery charging winding in the generating set is not
capable of powering the fan. Neither is the small charger
that is included in the battery kit. WhisperPower supplies
high quality battery chargers that continuously supply the
rated power. Chargers of other suppliers are often rated to
other standards and give the rated current (Amps) only for
a short period if at all.
To avoid the need of an extra heavy battery charger a
230 Volt fan on the radiator is recommended. One should
realize that the power for the fan must be decucted from
the output power of the generating set.

OTHER RECOMMENDATIONS AND WARNINGS
The battery should be secured for poor road conditions
and the terminals should be insulated. For extra safety the
battery can be enclosed in a wooden, plastic, fiberglas etc.
(non metal) box. Even when the earth return system is
applied a negative battery cable should be used and the
vehicle should not to be used as a conductor.
The battery cables are supplied in a standard length of
1.5m, if longer cables are required a larger cross sectional
area should be considered to compensate for voltage
reduction.
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.
