To reduce the risk of electrical shock and ensure the safe installation and operation of the APsystems Microinverter, the following symbols appear throughout this document to indicate dangerous conditions and important safety instructions. SAVE THESE INSTRUCTIONS! This manual contains important instructions for models YC1000-3 that must be followed during Installation and maintenance of the Photovoltaic Grid-connected Inverter. Specifications subject to change without notice - please ensure you are using the most recent update found at www.APsystems.com This indicates a situation where failure to follow instructions may cause a serious hardware failure or personnel danger if not applied appropriately. Use extreme caution when performing this task. This indicates information that is important for optimized Microinverter operation. Follow these instructions closely. Pollution degree 1 ： no pollution or only dry, non-conductive pollution occurs. The pollution has no influence. Radio interference statement CE EMC Compliance：The equipment can comply with CE EMC, which are designed to protect against harmful interference in a residential installation. The equipment could radiate radio frequency energy and this might cause harmful interference to radio communications if not following the instructions when installing and using the equipment. But there is no guarantee that interference will not occur in a particular installation. If this equipment causes harmful interference to radio or television reception, the following measures might resolve the issues: A) Relocate the receiving antenna and keep it well away from the equipment. B) Consult the dealer or an experienced radio / TV technical for help. Changes or modifications not expressly approved by the party responsible for compliance may void the user’s authority to operate the equipment. APsystems YC1000-3 Installation/User Manual 2 Important Safety Instructions Safety Instructions Do NOT disconnect the PV module from the APsystems Microinverter without first disconnecting the AC power. Only qualified professionals should install and/or replace APsystems Microinverters. Perform all electrical installations in accordance with local electrical codes. Before installing or using the APsystems Microinverter, please read all instructions and cautionary markings in the technical documents and on the APsystems Microinverter system and the solar-array. Be aware that the body of the APsystems Microinverter is the heat sink and can reach a temperature of 80°C. To reduce risk of burns, do not touch the body of the Microinverter. Do NOT attempt to repair the APsystems Microinverter. If it fails, contact APsystems Customer Support (61 (0)2 8034 6587) to obtain an RMA number and start the replacement process. Damaging or opening the APsystems Microinverter will void the warranty. Do NOT expose the connection to directed, pressurized liquid (water jets, etc.). Do NOT expose the connection to continuous immersion. Do NOT expose the AC connector to continuous tension (e.g., tension due to pulling or bending the cable near the connection). Use only the connectors and cables provided. Do NOT allow contamination or debris in the connectors. Use the cable and connectors only when all parts are present and intact. Use the terminator to seal the conductor end of the Engage Cable; no other method is allowed. Symbols replace words on the equipment, on a display Dangerous electrical voltage This device is directly connected to public grid, thus all work to the inverter shall only be carried out by qualified personnel. NOTICE, danger! This device directly connected with electricity generators and public grid. Danger of hot surface The components inside the inverter will release a log of heat during operation, DO NOT touch aluminum housing during operating. An error has occurred Please go to Chapter 10 “Trouble Shooting” to remedy the error. Person adequately advised or supervised by an electrically skilled person to enable him or her to perceive risks and to avoid hazards which electricity can create. For the purpose of the safety information of this manual, a Qualified "qualified person" is someone who is familiar with requirements for safety, personnel refrigeration system and EMC and is authorized to energize, ground, and tag equipment, systems, and circuits in accordance with established safety procedures. The inverter and endues system may only be commissioned and operated by qualified personnel.
