STARTER BATTERY
For starting, the Whisper requires a 12V starter battery
with the following capacity:
Model
M-SQ6
The generating set can be connected with the main engine
battery or have its own battery.
We strongly recommend the use of a separate battery for
the generating set and to keep the wiring system for the
propulsion engine and the domestic DC supply system
completely
separate
and
separate batteries.

However, the negative of all the batteries on the vessel
should be interconnected (when on earth) to avoid
difference in the voltage level of the earth on different
places causing trouble to electronic devices which might
be in the system.
The above recommendation is not valid for ships having
the starter battery of the propulsion engine or other
auxiliary equipment positive grounded. When this is the
case an expert should be consulted.
A battery switch may be used to interrupt the positive
connection.
The starter battery is charged by the alternator on the
engine. An additional battery charger will help to keep the
battery in good condition when the generating set is not
used. A battery charger is not included in the standard
supply. A high efficiency battery charging unit can be
ordered from WhisperPower which is able to charge both
the ship's main battery and the starter battery. Also a small
charger can be used to charge the starter battery only,
such as the IVO SMART 12/10. A battery switch and a
charger are included in the battery installation kits, art. no.

OTHER RECOMMENDATIONS AND WARNINGS
The battery should be secured for seagoing 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
vessel 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
to
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
discharged
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 Volt)
Before working (installation) on the system
read the sections on safety in the users
manual.
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 onboard as the
generating set itself cannot be equipped with such
equipment for every possible variation.
The vessel'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
on-board electrical system is properly installed by a
qualified electrician.
