• If a layer of ice has formed on the enclosure seal when temperatures are below freezing,
remove it prior to opening the product (e.g. by melting the ice with warm air).
• Do not disassemble the Power Unit and Connection Unit unless the ambient temperature is
at least 0°C and conditions are frost-free.
Damage to the product due to sand, dust and moisture ingress

Change to the names and units of grid parameters to comply with the grid-
connection requirements in accordance with Regulation (EU) 2016/631
(valid from April 27, 2019)
To comply with the EU grid-connection requirements (valid from April 27, 2019) the names
and units of grid parameters were changed. This change is valid from firmware version
≥ 3.00.00.R if a country data set for fulfilling the EU grid-connection requirements (valid from
2019-04-27) is set. Names and units of grid parameters for inverters with firmware version
≤ 2.99.99.R are not affected by this change and remain valid. This also applies from firmware
version ≥ 3.00.00.R if a country data set that is valid for countries outside the EU is set.
