CONNECTING CONSUMERS
INSTALLATION SHEET 7
SITUATION
Connection of consumers to
the system.
PROBLEM
Many batteries die prematu-
rely if they are discharged too
much. Too little power might be
delivered to critical consumers,
like navigation, radio and
emergency lights.
SOLUTION
Critical consumers are con-
nected directly to the battery.
Others, such as refrigerator,
main light and heating are
connected to the SMARTPASS.
When the Service battery is
down to a critical level, then
the SMARTPASS disconnects
these noncritical consumers.
TIP 7
See Tip 1, Tip 2, Tip 4, Tip 5
and Tip 6.
High current consumers
(>80A) should be connected
directly to the Service or
Starter battery.
