For any questions regarding installation on such systems, please contact REC directly. MOUNTING METHODS: MOUNTING HOLES The REC solar panels covered by this manual can be installed utilizing the mounting holes (11 mm x 6.6 mm (0.43 in x 0.26in)) on the underside of the panel (fig. 1-3). -
Page 11: Grounding
Local regulations may require grounding of the panels. Installers are responsible for ensuring compliance with relevant local regulations. Grounding must be done using an electrical connection from the panel frame. REC solar panels have a small round grounding hole posi- tioned near each corner of the panel on both the long side and the short side, (fig. -
Page 12: Cable Management
• To enable correct cooling and drying of the connectors, do not add extra protection to the connector, e.g., heat shrink, grease or tape. More detailed information is given in the Guide to Best Practice - Connections and Connectors which can be found via the REC online Down- load Center (www.recgroup.com/downloads) Fig. -
