Battery master switch
If a battery master switch is installed between the starter motor and the batteries, it
must be positioned as close to the batteries as possible.
The power must not be switched off directly after switching off the engine. In order
for the control units to store operational data and switch off any systems, it is impor-
tant to allow a 10 second delay before switching off the power.
The SCR system may need up to 30 minutes to cool the reductant doser in extreme
conditions. The battery master switch must not be switched off before then.
Status for post-running is sent out in CAN message DLN7. More information is
available in section DLN7 in 03:05 CAN interface.
