Corrective measures
• Select the parameter 250.02 Dt
and set the date. Select the
parameter 250.03 Tm and set the
time.
• Ensure that undamaged CAT5e
cables are used for communication
and that the cables are plugged in
correctly.
• Ensure that the communication bus
is equipped with a terminator at
both ends.
• Disconnect the loads, start the
generator, start the Sunny Island
and charge the battery.
• Ensure that all circuit breakers of
the Sunny Island inverters in the
Multicluster-Box are closed.
• Ensure that the cabling at
connection AC1 is correctly
installed.
• Ensure that undamaged CAT5e
cables are used for communication
and that the cables are plugged in
correctly.
• Ensure that the communication bus
is equipped with a terminator at
both ends.
Read off the pending and logged warn-
ings and errors and eliminate the
causes.
• Contact the Service (see Section 16
"Contact", page 161).
