For a better understanding of the programming of the system, please first read page 6 of the DBM20A
manual. Otherwise, the system may have to be reinstalled.
Please read the instructions for mounting and wire extension on page 8 of the DBM20A manual.
Please read the installation steps before performing for a better understanding.
Choice of the connection of the light blue wire
IGN:
For an alternator with charge cut-off, connect IGN to ignition (terminal 15). When the alternator
is switched off, DC / DC charging is carried out until the main voltage reaches 11.9V. The DC /
DC charge starts automatically when Umain is more than 13.3V.
For all other alternators: do not connect IGN, charge is switched off at main voltage 12.7V. The
DC / DC charge starts automatically when Umain is more than 13.3V.
1.
If necessary
, connect light blue lead IGN to ignition (terminal 15). Leave open without need.
2. Connect the IBS-DBS as shown above (red to Plus Main, blue to Plus Aux, black to minus).
3. Connect the relay to the green line (terminal 86) and the negative line (terminal 85).
4. Route the power wires (minimum 25mm2) from
Main Plus to Relay
and
Aux Plus to Relay
.
5. Connect the black (GND) wires.
6. Then connect the red (+ Main) wire (NOTICE: System starts up
see page 6 Programming the
system in the DBM20A manual). (Do not continue installation until standby mode is activated).
7. Now connect the green line of the IBS-DBS to the yellow Link / Prog line of the DBM20A.
8. Finally connect the blue (+ Aux) line.
If the relay was not detected during the programming step, because the Aux line was connected
afterwards, see the steps under
Relay not recognized - what to do?
Note
To ensure a safe installation, fuses must be installed in the red path (+ Main: 30A) and in the
blue path (+ Aux: 30A)!
