Corrective measures
• Check heat dissipation
(see Section 10.2 "Checking Heat
Dissipation", page 67).
• Contact the SMA Service Line (see
Section 16 "Contact", page 126)
If this event occurs frequently:
• Ensure sufficient ventilation.
• Check heat dissipation
(see Section 10.2 "Checking Heat
Dissipation", page 67).
• Disconnect the inverter after dark
(see Section 9 "Disconnecting the
Inverter from Voltage Sources",
page 63).
• Contact the SMA Service Line
(see Section 16 "Contact",
page 126)
• Plug the Electronic Solar Switch on
right up to the stop.
• Disconnect the inverter after dark
(see Section 9 "Disconnecting the
Inverter from Voltage Sources",
page 63).
• Replace surge arrester
(see Section 12.4 "Replacing Surge
Arresters Type II", page 90).
• Contact the SMA Service Line
(see Section 16 "Contact",
