Inverter RS Smart 2. Safety Instructions ELECTRIC SHOCK HAZARD Please read this manual carefully before the product is installed and put into use. This product is designed and tested in accordance with international standards. The equipment should be used for the designated application only. Refer to the specifications provided by the manufacturer of the battery to ensure that the battery is suitable for use with this product. The battery manufacturer's safety instructions should always be observed. Protect the solar modules from incident light during installation, e.g. cover them. Never touch uninsulated cable ends. Use only insulated tools.
Connections must always be made in the sequence described in the installation section of this manual. The installer of the product must provide a means for cable strain relief to prevent the transmission of stress to the connections. In addition to this manual, the system operation or service manual must include a battery maintenance manual applicable to the type of batteries used. The battery must be placed in a well-ventilated area. These servicing instructions are for use by qualified personnel only. To reduce the risk of electric shock, do not perform any servicing other than that specified in the operating instructions unless you are qualified to do so.
The product is used in combination with a permanent energy source (a battery). Even if the equipment is switched off, a dangerous electrical voltage can occur at the input and/or output terminals. Always switch the AC power off and disconnect the battery before performing maintenance. SELECTION OF WIRE CONDUCTORS Use flexible multistranded copper cable for the battery connections. The maximum diameter of the individual strands is 0,4mm/0,125mmІ (0.016 inch/AWG26). A 25mmІ cable, for example, should have at least 196 strands (class 5 or higher stranding according to VDE 0295, IEC 60228 and BS6360).
An AWG2 gauge cable should have at least 259/26 stranding (259 strands of AWG26) Maximum operating temperature: ≥ 90°C Example of suitable cable: class 5 “Tri-rated” cable (it has three approvals: American (UL), Canadian (CSA) and British (BS)). In case of thicker strands the contact area will be too small and the resulting high contact resistance will cause severe overheating, eventually resulting in fire. RISK OF INJURY OR DEATH The internals can carry a 400-500V DC voltage even when the product is off! Input and/or output terminals may still be dangerously energized, even when the equipment is switched off. Always disconnect all power connections (e.g.
the battery, DC solar isolator, etc) and wait at least 5 minutes before carrying out work on the product. The product has no internal user-serviceable components. Do not remove the front plate or operate the product if any panels have been removed. All servicing must be undertaken by qualified personnel. Please read the installation instructions in the installation manual before installing the equipment. Page 2 Safety Instructions
