The installation information in this instruction manual is intended for specialist
companies that are familiar with the guidelines and safety precautions to be applied
during the installation of vehicle accessory parts.
All other chapters are intended for the users.
5Intended use
The “DC kit” extension kit is suitable for equipping the following Dometic air
conditioning units for DC power drive operation:
If the air conditioning unit does not have a heat pump (see instruction manual for air
conditioning unit), the inverter may only be used for cooling by the air conditioning
unit, not for heating mode, as the heating elements consume more current than the
inverter can generate in continuous operation.
6Technical description
The extension kit consists of the following components:
•The charging current distributor with low-voltage cut-off regulates the current
distribution between the starter battery, supply battery and light system, as well
as the operation of the air conditioning unit. It prevents the battery and the electronics in the vehicle from overloading.
•The inverter supplies the air conditioning unit with the necessary input voltage of
230 Vw. The inverter generates this 230 V input voltage from the DC on-board
supply in the vehicle.
15
EN
Technical descriptionDC-Kit PP12, DSP-T12/24
The built-in priority circuit is intended for distributing voltages in vehicles with
two available current supplies. If there is mains voltage present at the device, this
is prioritized. This ensures that the limited power of the battery is not used
unnecessarily. If there is no mains voltage present, the DC on-board supply is
used.
•The remote control can be used to switch the inverter on and off.
The charging current distributor has two relays that are used as follows:
•Power relay (Batt. 1/Batt. 2)
to connect the starter and consumer battery
•Control relay
to switch the compressor on and off

Explanation
6.1How the DC kit functions
The DC kit measures the light system voltage UD+ and compares this value against
the value of the switch-on voltage Ue.
The voltage value Ue can be adjusted for ECL-76 and ECL-102 (12.5 V – 14.0 V). For
ECL-103, the voltage value Ue is 26.6 V.
16
EN
DC-Kit PP12, DSP-T12/24Technical description
Supply from the battery with motor switched on
If the light system voltage exceeds the voltage value Ue (UD+ > Ue), relay contact
Batt. 1/Batt. 2 of the power relay closes. The starter battery and the consumer
battery are therefore connected in parallel with low resistance and are charged
together by the light system. In addition, the contact I2/I4 opens. This activates the
air conditioning unit.
If the light system voltage falls below the switch-off value Ua for the charging current
distributor due to the high load from the air conditioning unit, relay contact Batt. 1/
Batt. 2 opens and the parallel connection between the starter battery and the consumer battery ends. The light system now charges the starter battery. If the vehicle
has a connecting cable between the two batteries, the consumer battery is also
charged.
In addition, the contact I2/I4 closes. This switches off the compressor of the air
conditioning unit. The air conditioning unit fan and the inverter remain in operation.
The lower limit value Ua can be adjusted for ECL-76 and ECL-102 (10.5 V – 12.5 V).
For ECL-103, the voltage value Ua is 23.4 V.
As soon as the voltage in the consumer battery has reached the switch-on value Ue
for the charging current distributor, the compressor of the air conditioning unit
switches on again.
If the voltage in the consumer battery drops further and falls below the switch-off
point for the inverter, the inverter switches off.
Supply from the battery with motor switched off
If the vehicle engine is switched off (UD+ = 0 V), relay contact Batt. 1/Batt. 2 and
relay contact I2/I4 are open. The air conditioning unit can be operated and only
takes power from the consumer battery. If the battery voltage falls below
Ubatt = 10.5 V/21 V, the inverter switches off. There is no longer any voltage at
the corresponding socket and the air conditioning unit switches off.
As soon as the power from the consumer battery reaches the inverter's switch-on
point, the socket is supplied with voltage again. The air conditioning unit has to be
switched back on manually.

NOTICE!
A
I
The following work must be carried out with caution and only by persons
with the necessary skills and knowledge. This is because incorrect
adjustment of the switch-on and switch-off voltages can cause the air
conditioner to malfunction and may cause the vehicle’s electrical system
to fail.
NOTE
The voltage scale shown on the charging current distributors is a guide.
If different values are set, these must be checked using a suitable voltage
measurement device. An externally adjustable laboratory power supply
can be connected to terminals GND and D+ for this purpose.
➤ Insert a screwdriver into the axis of the potentiometer (fig. 0, page 9).
Turning the axis clockwise increases the voltage threshold value, turning it
counter-clockwise reduces the voltage threshold value.
NOTE
We recommend against setting a switch-off voltage below 11.5 V.
