Damage to the enclosure seal in subfreezing conditions
If you open the inverter when temperatures are below freezing, the enclosure seals can be
damaged. This can lead to moisture entering the inverter.
• Only open the inverter if the ambient temperature is not below 0°C (32°F).
• If a layer of ice has formed on the enclosure seal when temperatures are below freezing,
remove it prior to opening the inverter (e.g. by melting the ice with warm air). Observe the
applicable safety regulations.
Damage to the product due to sand, dust and moisture ingress
Sand, dust and moisture penetration can damage the product and impair its functionality.

• Only use listed rain-tight or liquid-tight conduit fittings to attach the conduits to the product.
Damage to communication assembly in the inverter due to an interruption in
the voltage supply during the firmware update
The firmware update to a version higher than 2.03.61.R may take approx. 30 minutes. The
inverter must be continually supplied with voltage for the entire course of the firmware update.
• Ensure that the inverter is supplied with voltage during the firmware update to a version
higher than 2.03.61.R.
