such as the WBC Handy 70. A battery switch and a
charger are included in the battery installation kit (refer to
3.4).

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 1.5
m, 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.
As explosive hydrogen gases may be
discharged during charging, the battery
should be located in a well ventilated room.
Ensure that the supplied battery cable
connectors are properly fitted and never
remove during or shortly after charging as
sparking can occur, which may ignite the
hydrogen gasses.

AC power system (230 / 400 Volt)
The electric power supplied by the generator
is of a high voltage and dangerous to people.
Before working (installation) on the system
read the sections on safety in the users
manual.
Realise hat people are not used to having
230/400 Volt available on a vehicle. Put
warning signs on wall sockets and on junction
boxes. Instruct non-regular users of the
vehicle. Warn maintenance personal of
garages that do service on the vehicle.
Generators used on vehicles that are
operated in a hazardous environment have
often to fulfil special regulations and additional
measures have to be taken accordingly.
Be sure that all electrical installations (including all safety
systems) comply with all required regulations of the local
authorities. All electrical safety/shutdown and circuit
breaking systems have to be installed on board as the
generating set itself cannot be equipped with such
equipment for every possible variation.
The vehicle
’s power supply system should be suitable and
safe for the AC voltage which is 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 is properly installed by a qualified
electrician.
The W-SQ20 can be connected as a single phase 230 Volt
generator by an arrangement of the wiring in double
DELTA. When the wires are arranged in STAR the output
will be 230/400Volt.
Connected as a three phase 230/400 Volt generator, 3x
400 Volt is available between the phases. At the same
time 230 Volt is available between every phase and
neutral.
When applying 3 phases the installation should be laid out
in such a way that there is a reasonable balance of load
between the three phases.
To avoid problems with unbalanced loads one could apply
a 400V 3 phase to 230 Volt single phase transformer.
