3 Description and appropriate use
The electrical management system Electrobloc EBL 208 S G consists of:
●the LAS 1218 charger module
●the 12 V distribution
●fuses for the 12 V circuits
●a battery monitor module
●other control and monitoring functions
The charger module is a primary controlled switch-mode power supply. This
modern switching technology achieves high charging performance at a com-
pact size and low weight.
▲Only use original fuses rated as specified in the instruction manual.
▲Danger of burning! During operation the back of the Electrobloc gets
hot. Do not touch.
▲Danger of explosion from formation of detonating gas due to an incor-
rectly set battery selector switch, defective batteries, defective Electrob-
loc or an excessively high battery working temperature (more than
30 °C).
▲The AES refrigerator fuse may only be used if a AES refrigerator is con-
nected. Otherwise, the living area battery may get totally discharged. Bat-
tery damage is possible.
▲An incorrectly set battery selector switch damages the living area battery.
▲Disconnect the Electrobloc from the mains before adjusting the battery
selector switch.
▲When the living area battery is separated from the Electrobloc by the bat-
tery cut-off switch, the frost protection valve of the heater system opens.
▲Before and after shutdown, the living area battery must be fully recharged
to avoid battery damage. For this purpose the vehicle must be connected
to mains supply for a minimum of 12 hours with an 80 Ah battery and
16 hours with a 160 Ah battery.
▲Do not operate the Schaudt solar charge regulator without a battery. This
might damage the solar charge regulator or any connected consumers. If
the battery is going to be changed or removed, please first take off the pos-
itive lead "+ Solar Module" on the solar charge regulator.
▲To avoid voltage peaks during warm-up, do not connect the generator until
it is running in a stable manner. Otherwise, the Electrobloc, 12 V consum-
ers or other connected equipment might get damaged. It is essential that
the generator complies with the mains supply specifications.

6.3 Battery monitor
Automatic disconnector The battery monitor compares the voltage of the living area battery to a refer-
ence voltage. As soon as the battery voltage falls below 10.5 V, all 12 V con-
sumers are switched off. Only the entrance step, the frost protection valve and
the AES refrigerator are still powered. The automatic disconnector is not trig-
gered by short-term low voltage (less than 2 seconds), caused by high current
when switching on consumers.
If overload or an insufficiently charged living area battery causes the voltage
to fall so low that the automatic disconnector is triggered, any consumers
which are not essential should be switched off.
You may be able to switch on the 12 V power supply for a short time. To do
this, switch on the 12 V main switch on the control and switch panel.
However, if the battery voltage remains below 11.0 V, you cannot switch on
the 12 V power supply.
Fully charge up the living area battery as soon as possible. For more informa-
tion see the description of battery voltage.
7 Maintenance
The Electrobloc EBL 208 S G requires no maintenance.
Cleaning Clean the Electrobloc with a soft, slightly damp cloth and mild detergent.
Never use spirit, thinners or similar substances.
Do not allow fluid to penetrate the inside of the Electrobloc.
8 Shutting down the system
Disconnecting the living
area battery from the
12 V power supply
