Solution
Reset remote: 1) disconnect
remote cable from inverter for 5
seconds and reconnect; 2) check
RJ11 cable connection on back
of remote (see fi gure 2-2).
Important: ensure the RJ11
connector is pushed into the
correct port; you should feel/
hear "click" when the connection
is made.
Ensure inverter batteries are
connected and inverter is
operating correctly; inverter
should be able to invert and
power AC loads from batteries
(ensure no AC power is
connected to the inverter AC
inputs).
Press any button to reactivate
remote (or turn Power Saver
mode Off).
Check communications cable
from inverter to remote;
ensure: 1) it is connected to
the REMOTE port, 2) the correct
communications cable is used
(a 4-conductor telephone
cable may be substituted to
determine if cable is good).
Ensure inverter batteries are
connected and inverter is
operating correctly without
any AC power connected (can
invert and power AC loads from
batteries).
