Page 13: Mounting Methods: Slide In Systems
MOUNTING METHODS: MOUNTING HOLES The REC solar panels covered by this manual can be installed utilizing the four mounting holes (11 x 6.6 mm) on the underside of the panel (fig. 8 & 9) in conjunction with a device, e.g., screws, lockbolts or structural blind fasteners, with specifications suitable for the installation (fig. 10). -
Page 14: Drainage Holes
DRAINAGE HOLES On the long and short sides of the REC frame small drainage holes can be found that allow humidity and water to exit the frame easily and minimize damage (fig. 12). These are spaced 55 mm from the corner on 60-cell format panels and 60 mm on 72-cell format panels. These holes must not be used for mounting the panel, and they must not be covered by any part of the mounting structure. -
Page 15: Connections And Connectors
CONNECTIONS AND CONNECTORS The connector type(s) used on REC panels are indicated in the product specifications at the rear of this manual. The connector IP rating is only valid when correctly connected. All connectors and cables must be secure and tight as well as electrically and mechanically sound. UV-resistant cables and connectors approved for outdoor use must be used. -
Page 16: Panel Maintenance
DISPOSAL OF OLD ELECTRICAL AND ELECTRONIC EQUIPMENT Panels should be recycled at the end of their useful life according to local guidelines and regulations.
