5 Any other application may causepersonal injury or property to the product, changes or modifications, are only permitted with the express writtenpermission of SMA Solar Technology AG. Unauthorized alterations will void guarantee andwarranty claims and in most cases terminate the operating license. SMA Solar Technology AGshall not be held liable for any damage caused by such use of the product other than that described in the Intended Use section does not qualify as theintended enclosed documentation is an integral part of this product. Keep the documentation in aconvenient place for future reference and observe all instructions contained type label must remain permanently attached to the InformationThis section contains safety information that must be observed at all times when working on or withthe prevent personal injury and property damage and to ensure long-term operation of the product,read this section carefully and observe all safety information at all to life due to high voltages of the PV arrayWhen exposed to light, the PV array generates dangerous DC voltage, which is present in the DCconductors and the live components of the inverter.

6 Touching the DC conductors or the livecomponents can lead to lethal electric shocks. Prior to performing any work on the inverter, always disconnect the inverter from voltagesources on the AC and DC sides as described in the inverter manual . When doing so, notethat even if the DC load-break is switched off, there will be dangerous direct voltage presentin the DC conductors of the SafetySMA Solar Technology AGInstallation manualMD485-40-IA-en-106 Damage to seals on the enclosure lids in subfreezing conditionsIf you open the enclosure lids when temperatures are below freezing, the enclosure seals can bedamaged. This can lead to moisture entering the inverter. Only open the enclosure lids if the ambient temperature is not below -5 C If a layer of ice has formed on the seal of the lid when temperatures are below freezing,remove it prior to opening the enclosure lids ( by melting the ice with warm air).
