Page 6: Cautions
User Manual 1.3 Cautions 1.3.1 Installation principles The inverter must only be installed by professional technicians. The professional technician is required to meet requirements as follows: Know electronic, electrical wiring and mechanical expertise, and be familiar with electrical and mechanical schematics. Be familiar with local standards and relevant safety regulations of electrical systems.
Page 7 User Manual Important Safety Instructions Danger to life due to a high voltage inside the inverter! All work must be performed by a qualiﬁed electrician. • DANGER Children and persons with reduced physical sensory abilities, mental • capabilities, or lack of experience and knowledge should not use this equipment unless supervised or instructed.
Page 8 User Manual Make sure the input DC voltage is less than the maximum value. Over- voltage may cause permanent damage to the inverter or other losses, WARNING which will not be covered by the warranty! Before attempting any maintenance, cleaning or working on any circuits connected to inverter, authorized service personnel must disconnect WARNING both AC and DC power from inverter.
Page 9 User Manual • Authorized service personnel must use insulated tools when installing or working with this equipment. • PV modules should have IEC 61730 Class A rating. • Do not touch either the positive or negative pole of PV connecting device.
Page 10 User Manual • Lightning will cause a damage either from a direct strike or from surges due to a nearby strike. • Induced surges are the most likely cause of lightning damage in majority or installations, especially in rural areas where electricity is usually provided by long overhead lines.
Page 11 User Manual • Spark gap devices are not suitable to be used in DC circuits once conducting, they won’t stop conducting until the voltage across their terminals is typically more than 30 volts. Anti-Islanding Effect The islanding effect is a special phenomenon where a grid-connected PV system still delivers power to the nearby grid when voltage losses occur in the power system.
