Ac Power System (230 Volt) - Whisper Power M-SC6 Installation Manual

INSTALLATION
3 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.
In the negative battery cable a 250 Amp starter battery
switch could be applied to switch off the battery. 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
the 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 are 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 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.
1 FUSE
An output fuse (from the generating set to the system)
should be installed to protect the installed electrical
system. The following maximum output current applies for
each separate phase:
Model
M-SC 6 – 3000 rpm
M-SC 8 – 3000 rpm
M-SC 10 – 3000 rpm
The fuses must be of the slow reacting type. For electrical
motors connected to the system, a motor protection switch
must be installed
