The Electroblock EBL 220-2 consists of:
F A charging module for recharging all of the connected batteries
F The complete 12 V distribution system
F The fuses for the 12 V power circuits
F A battery monitor module
F Other control and monitoring functions
A DT ... or LT ... control and switch panel as well as an ST ... switch panel(to provide full range of functions) must be connected up to run it. Thesedevices control the electrical functions in the motorhome’s living area as wellas the accessories.
Connection options are available for up to two additional battery chargingunits and a solar charger.
Flat vehicle fuses are used to protect the various circuits. The only excep-tions are the step and the frost protection valve

F Overload
F Short circuit
230 V AC voltage ±10 %, 47 -- 63 Hz sinewave, protection class I
12 V outputs shall only be loaded up to a maximum of 90 % of the ratedcurrent of the associated fuse (see installation instructions or front plate).
Y This device is exclusively designed for installation into a vehicle.
3.1 Battery functions
6-cell lead-acid or lead-gel batteries from 55 Ah upwards
Simultaneous starter battery and living area battery charging via alternator,parallel battery switching via an isolation relay
Battery isolation (activated from the DT/LT ... control and switch panel) cutsoff the following connections from the living area battery:
F All 12 V consumers
F The frost protection valve
This prevents the living area battery from being slowly discharged by closed-circuit current whilst closing down the vehicle.
The batteries can still be charged using the Electroblock, the alternator, anauxiliary charging unit or the solar charger, even when the battery isolation isactivated.
The switching option provided by the battery selector switch ensures opti-mum charging of the two different types of battery, lead-acid and lead-gel.

The battery monitor of the control and switch panel DT/LT ... with dynamicvoltage wave continuously monitors the living area battery. It switches off“earlier” with small discharge currents than with large ones. This enhancesthe total discharge protection. Monitoring also occurs when the device isswitched off. Depending on the current consumption, a warning message isdisplayed once the value falls below 12 V.
If the living area battery voltage continues to drop and falls below 10.5 V, thebattery monitor immediately switches off each 12 V consumer. The controland switch panel also switch off automatically. Only the anti--freeze valve isstill supplied with current to ensure that it remains closed. Prior to shutdown,all the switching states and the battery capacity value are stored andrestored after switching on.
If an overload or an insufficiently charged living area battery causes the vol-tage to fall so low that the automatic disconnection is triggered, any consu-mers which are not essential should be switched off.
You may be able to switch on again the 12 V power supply for a short timeunder certain circumstances. In this case you must switch on the 12 V mainswitch on the DT/LT ... control and switch panel.
However, you cannot switch the 12 V power supply back on if the batteryvoltage remains below 11.0 V.
Fully charge up the living area battery as soon as possible. For more infor-mation, see the “Battery voltages” description in the associated DT/LT ...control and switch panel instruction manual.
When using a DT/LT ... control and switch panel: approx. 20 mA;12.6 V battery voltage after being disconnected from the mains for 10 min-utes; battery isolation is not activated; control and switch panel illuminationand main switch are switched off.

3.2 Additional functions
This relay supplies the AES/compressor refrigerator with power from thestarter battery when the vehicle engine is running and the D+ connection islive. An AES/compressor refrigerator is powered by the living area batterywhen the vehicle engine is switched off.
This feature provides an automatic trickle charge for the starter battery up toa 6 A maximum when the 230 V mains is connected to the Electroblock.
The “Step” output is protected with a self-resetting fuse.
If there is a fault, e.g. overcurrent, the self-resetting fuse will disconnect therelevant circuit.
This fuse resets automatically approx. 1 minute after the fault has been rec-tified.
The circuit is protected with a 15 A fuse.
Maximum permitted charging current 14 A, protected by a 15 A fuseEither the living area battery or the living area battery and the starter batterywill be charged, depending on the type of the solar charger being used.
The power supply to these consumers will be disconnected automatically assoon as the engine is running (the D+ connection supplies the voltage in thiscase). The awning light can also be used if the 12 V power supply isswitched off.
The tank heating is switched on from the DT/LT ... control and switch panel.
The switch panel ST ... is an optional extension for the electroblockEBL 220-2. Via three buttons consumers can be switched off individually.
If the switch panel ST ... is not available, a strapping plug must be connec-ted to block BL11 of the electroblock EBL 220-2 (also see block diagram,appendix E).
