tion is made directly to the
battery, the positive and ne-
gative leads are to be protec-
ted by fuses.
Secure all cables with clips!
If power pack units are used,
care must be taken to ensure
that the device can only be
operated with safety extra-
low voltage (SELV), in accor-
dance with EN 60742.
Note: As an accessory Truma
can supply a battery holder
(Art. No. 50000-27700) for
operation with a 9 V mono-
bloc battery.
Attention: Sustained
operation is not possible
with 9 V connection with
the Sonatic L!
In order to achieve maximum
operational duration, we re-
commend the use of an
alkali/manganese battery.
