ELECTRICAL INSTALLATION
3.1
DIGITAL DIESEL CONTROL SYSTEM
The standard electrical control system is in 12 Volt with
negative earth. Non-earth return is available as an option. The
engine is controlled by a highly advanced microprocessor based
system: Digital Diesel Control, which has both a local control
and a remote panel.
3.2
REMOTE CONTROL
A remote control panel also containing a microprocessor is
included in the delivery, as well as a 10 m 8-pole
communication cable (Figure 20). Other lengths are available
on request. A longer (up to 30 m) cable can be connected if
required. For distances exceeding 30 m, please consult the
WhisperPower service department.

The control panel can be mounted in the dashboard using the
plastic sawing template. For dimensions, refer to the drawings
in Chapter 5.
Two more remote control panels (slave panels) can be put in
parallel using the modular connectors on the back of the units.
Actually, the slaves are regular remote control panels offering
all functions again.
When using the factory settings, installation is very simple: just
plug in both end of the communication cable and the genverter
is ready to use (Figure 20).
3.3
ACOUSTIC ALARM OR WARNING LAMP
An external max. 150 mA relay can be connected in order to
generate an acoustic warning, light a warning lamp, etc. Be
aware of polarity as some relays have a diode inside and must
be connected plus to plus en minus to minus as indicated
(Figure 21).

CONNECTION FOR EMERGENCY STOP /
FIRE ALARM SWITCH
Figure 22: Connection for emergency stop / fire alarm switch
To connect an emergency stop button or to stop the generator
automatically in case of a fire alarm, you can use the bypass
connection between fastons J7 and J18 on the backside of the
local control panel (Figure 22). To do so, remove this bypass
connection and then replace it by an emergency switch or a
potential free fire alarm switch with normally closed contacts.
