work or maintenance, contact qualified electrician. Further
instructions can be found in the installation manual of the Sunny
Island 3324/4248.
To prevent possible errors, wait at least 30 seconds before switching the

components of the system for possible faults or incorrect
parameter settings before attemping to restart the system.
You must wait at least five minutes to allow the capacitors to
completely discharge before switching the DC circuit breaker on
