4 Marking Each component shall carry the following clear and indelible markings: – name, monogram or symbol of manufacturer/supplier; – type or model number; – serial/batch number, if practical; – the design service use of this component; outdoor unprotected, outdoor protected, indoor unconditioned and indoor conditioned; – polarity of terminals or leads (only colour coding is not permissible); – maximum system voltage for which the component is suitable; – nominal and minimum values of the power consumption, as specified by the manufacturer for the product type. The date (and preferably time) and place of manufacture shall be marked on the component or be traceable from the serial or batch number. NOTE Small components such as wires, connectors, fuses, etc. need not have these elaborate markings. The minimum information is name/monogram/symbol of manufacturer or supplier and the type or model number. 5 Documentation 5.1 General The documentation shall contain the following information (if relevant): − compliance with relevant standards (this is especially important with respect to European Directives and the related CE marking); − installation and disconnection instructions; − operating instructions; − service use of the component (see 6.1); − technical data (circuit diagram and technical specifications); − troubleshooting instructions; − safety warnings and instructions; − information on spare parts; − warranty; − instructions for decommissioning and disposal.
In particular, the documentation shall indicate (if relevant): a) Conditions of surroundings 1) Range of operating temperature 2) Range of storage temperature 3) Maximum relative humidity b) Physical properties of the component 1) Dimensions of the enclosure 2) Weight 3) Properties of the enclosure (material) 4) Fasteners 5) Protection class (IP and IK Code) 6) Connecting terminals 7) Cables (inlet, pull relief, cross-sections) 8) Spare parts c) Electrical properties of the component 1) For charge controllers − Listing of incompatible and compatible battery types − Nominal voltage of input and output (V) − Maximum module current (A) − Maximum load current (A) − Type of controller (series controller, shunt controller, etc.) − Working principle (PWM, two-point-regulation, state of charge algorithm, etc.) − All used thresholds (V) − Temperature compensation for the thresholds (mV/°C/cell) − Quiescent current − Curve indicating input and output power/current vs. ambient temperature
