Review all WARNING and NOTE callouts to ensure safe and proper operation of the SolarMagic powerstring optimizer module. • Failure to follow these instructions may result in injury or death • Failure to adhere to these instructions may result in voiding the factory warranty. Installation must be performed by authorized service and installa- tion personnel aware of the procedures required to avoid the risk of electrical shock and general high-voltage safety procedures. Na- tional Semiconductor does not assume liability for loss or damage resulting from misuse or improper handling, or injuries caused by improper installation practices. Symbols used on the product and in this document. This symbol is used to indicate WARNING This symbol indicates ELECTRICAL SHOCK HAZARD This symbol indicates HOT SURFACE. This manual contains important instructions for the SolarMagic powerstring optimizer SM5400. 4 To avoid risk of electrical shock or fire, do not attempt to disassemble or repair the SolarMagic powerstring optimizer. It contains no user-serviceable parts and requires no maintenance. Tampering with or opening the module will void the factory war- ranty. See warranty for instructions on obtaining service. To reduce risk of fire and shock hazard, install this device with strict adherence to the National Electrical Code (NEC) ANSI/ NFPA 70, Canadian Electrical Code (CEC) C22.1-09, EU/EEA Electrical Codes and applicable local electrical codes. Wear appropriate and suitably rated Personal Protective Equipment (PPE). Remove all metallic jewelry prior to installing or servicing solar arrays equipped with the SolarMagic powerstring optimizer to re- duce the risk of contacting live circuitry. Do not attempt to install or service during inclement weather such as rain and snow, under windy conditions, or in extreme humidity. Use only accessories recommended or sold by SolarMagic dealers or distributors. Doing otherwise may result in risk of fire, electric shock, or injury. To avoid risk of fire and electric shock, make sure that exist- ing cables and connectors are in good condition and are not under- sized. Use only connectors of the same type and rating as present in the installation and insure that they are properly sized for the cable cross section and diameter when making cable splices. Do not operate the SolarMagic powerstring optimizer with damaged or substandard wiring (e.g. non UV resistant) or connectors (e.g. 5 www.solarmagic.com connectors from a different manufacturer. Check all cable glands to make sure that they are tight. Do not operate the SolarMagic powerstring optimizer if it has been physically damaged or subjected to forces beyond its design. Do not disconnect under load. Authorized service personnel should reduce the risk of electrical shock by disabling and discon- necting all AC and DC power sources from the PV system prior to attempting any maintenance or working on any circuits connected to the SolarMagic powerstring optimizer. Turning off the inverter alone will not reduce this risk. Internal capacitors within the in- verter can remain charged for several minutes after disconnecting all power sources. All strings that feed into a common combiner box that is a part of the array being serviced must be covered by an opaque material to disable the DC source. Isolate each string by removing the fuses for all strings that feed into a combiner box. To reduce the risk of burns…
