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. See figure 27. 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

Automatic starting and stopping
Automatic start/stop
Mastervolt cannot be held responsible for
damage caused by the unattended running
generator using the auto-start/stop mode
or interval mode.
Using the auto-start/stop (interval) mode
the generator can start unexpectedly.
When working on the electrical system, the
3 Amp fuse must be removed from the
control panel and the battery plus cable
must be removed from the battery.
In the delivery are warning stickers to stick on
several parts of the electric installation
(transfer switch, distribution box, etc.) to warn
for automatic start)
The Mastervolt Digital Diesel Control system offers several
options for automatic starting and stopping.
Access to this menu and other menus could be blocked.
For de-blocking and setting up this options refer to the
APPENDIX of the DDC user’s manual.
One of these options is to monitor a second battery (not
being the starter battery) to start the generator
automatically when the voltage of this battery drops below
a certain setting.
Other names for this second battery are “auxiliary battery”,
“service battery”, ”users battery” or “consumers battery”.
We will refer to this battery as “the second battery”(BAT2).
In some menus the starter battery could be indicated as
“the first battery” (BAT1).
A sense wire to monitor the second battery should be
connected (attention polarity!) to the connector on the
back of the remote panel. Refer to fig. 29. The sense wires
must be connected directly on the second battery before a
main switch and be protected by a 3 Amps fuse.
(Monitoring the generator starter battery does not require
an extra sense connection)
Settings
When one want to apply other settings than the factory
settings refer to the DDC users manual, especially to the
APPENDIX.
2 STARTER BATTERY
For starting, the Whisper requires a 12V starter battery
with the following capacity:
Model Minimum capacity
Whisper 6 60Ah
Whisper 10 60Ah
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
vehicle engine and the domestic DC supply system
completely separate and individually connected to
separate batteries.

However, the negative of all the batteries on the vehicle
should be interconnected 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 vehicles having
