c. Test the solar panel connection
by touching the positive (+)
wire from the solar panel onto
the Test terminal (T).
•If the alarm led does not flash
then it is OK.
•If the alarm led flashes quickly
then it is not OK. Check the
polarity and test again. (There
must be some light on the solar
panels for this test to work).
If OK connect to the Solar
positive (+) terminal.
d. Connect the negative (-) wire
from DC load circuit to the
load negative (-) terminal and
connect the positive wire from
the load to the load positve
