2 Safety2.1 Appropriate UsageThe ZDNY Series is a PV inverter which converts the DC current of a PV generator into AC current and feeds ir into the public grid.
Surge protection devices (SPDs) for PV installation
Over-voltage protection with surge arresters should be providedwhen the PV power system installed.The grid connected inverter is not fitted with SPDs in both PVinput side and MAINS side.WARNING!
Lightning can cause damage either from direct strike or from surges due to a nearbystrike.
Induced surges are the more likely cause of lightning damage in the majority of installations, especially in rural areas where electricity is usually by long overhead lines. Surgemay be induced on both the PV array conduction and the a.c. cables leading tothe building.Specialists in lightning protection should be consulted during the end use application.Using appropriate external lightning protection, the effect of a direct lightningstrike into a building can be mitigated in a controlled way, and the lightningcurrent can be discharged into the ground.Installation of SPDs to protect the inverter against mechanical damage and
excessive stress include a surge arrester in case of a building with external lightning protection system (LPS) when separation distance is kept.To protect the d.c. system, surge suppression device (SPD type2) should be fittedat the inverter end of the d.c cabling and at the array, located between the inverter and the PV generator, if the voltage protection level (VP) of the surge arresters is greater than 1100V, a additional SPD type 3 required for surge protection for electricaldevices.To protect the a.c system, surge suppression devices (SPD type2) should be fitted at the main incoming point of a.c supply (at the consumer’s cutout), located between the inverter and the meter/distribution system; SPD (test impulse D1) for signal line according to EN 61643-21.All d.c cables should be installed to provide as short runs as possible, and positiveand negative cables of the same string or main d.c supply should be bundledtogether,avoiding the creation of loops in the system. This requirement for short runs and bundling includes any associated earth/bundling conductors.Spark gap devices are not suitable to be used in d.c circuits as once conducting,they won’t stop conducting until the voltage across their terminals is typically more than 30 volts.
2.2 Important Safety Instructions • All work on the inverter must be carried out by qualified electrician.• The appliance is not to be used by children or persons with reduced physical sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction.• Children should be supervised to ensure that they do not play with the appliance.DANGER!DANGER TO LIFE DUE TO HIGH VOLTAGES IN THE INVERTER!During operation, the upper lid of the enclosure and the enclosurebody may become hot.• Only touch the lower enclosure lid during operation.
CAUTION!DANGER OF BURN INJURIES DUE TO HOT ENCLOSURE PARTS!
• Do not stay closer than 20 cm to the inverter for any length of time.
