3 Description and appropriate use
The Electrobloc EBL 99 G is designed as a main power distributor for
motorhomes/caravans. The Electrobloc is a permanent installation. The Elec-
trobloc is for charging batteries and supplying 12 V appliances with power.
The electrical management system Electrobloc EBL 99 G consists of:
P
The LAS 1218 charger module
P
The 12 V distribution
P
Fuses for the 12 V circuits
P
A battery monitor module
P
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.
A control and switch panel has to be connected for operation. This control and
switch panel controls the electrical functions in the living area of in the
motorhome, including accessories.
W Danger of burning! During operation the back of the Electrobloc gets
hot. Do not touch.
W Danger of explosion from formation of detonating gas due to an incor-
rectly set battery selector switch, defective batteries, defective Elec-
troblocor an excessively high battery working temperature (more than
30 °C).
W 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.
W An incorrectly set battery selector switch damages the living area battery.
W Disconnect the Electrobloc from the mains before adjusting the battery
selector switch.
W If the living area battery is separated from the Electrobloc using the 12 V
main switch at the control and switch panel, the frost protection valve of
the heater system opens. Water may be lost. For more information, see
the instruction manual of the heater system.
W 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
24 hours with a 160 Ah battery.
W 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 "+ Solarzelle" (+ Solar Module) on the solar charge regulator.
W To avoid voltage peaks during warm-up, do not connect the generator until
it is running in a stable manner. Otherwise, the Electrobloc, the 12 V con-
sumers or other connected equipment might get damaged. It is essential
that the generator complies with the mains supply specifications.
W The mains supply on board car ferries might not always be perfect. There-
fore, never connect the Electrobloc to the mains on car ferries. Otherwise,
the Electrobloc, the 12 V consumers or other connected equipment might

Instruction Manual Electrobloc EBL 99 G
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 via the main switch relays 1 and 2. Only the frost pro-
tection valve is still powered. The automatic disconnector is not triggered by
short-term low voltage (less than 2 seconds), caused by high current when
switching on consumers.
If an overload or an insufficiently charged living area battery causes the volt-
age 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 the
12 V power supply back on.
Fully charge up the living area battery as soon as possible. For more informa-
tion see the description of battery voltage.
