REC Installation Manual - REC Alpha Series - IEC /
Rev A . Ref: NE
MOUNTING METHODS: SLIDE IN SYSTEMS
When installing using slide in systems the mounting system must meet the same specifications including grip lengths, depths and spacing as
specified for clamping and the mounting system must be able to withstand the correct load pressures.
When installing solar panels using a slide-in system, the drainage holes found in the underside of the panel frame (see fig. ) must not be covered.
For any questions regarding installation on such systems, please contact REC directly.
MOUNTING METHODS: MOUNTING HOLES
REC Alpha Series panels can be installed utilizing the four mounting holes ( x . mm) on the underside of the panel at a distance of mm from the
corner (fig. ) in conjunction with a device, e.g., screws, lockbolts or structural blind fasteners, with specifications suitable for the installation (fig. ).
When installing using mounting holes, the frame and panel edge of each panel must be supported by two rails (figs. a & b) of aluminium or galvanized
steel suitable for the application and appropriate for the local environment. Observe the following procedures when using mounting holes:
• The mounting construction must be of a corrosion resistant material, e.g., aluminum or galvanized steel, and appropriate for the local
environment,
• All four mounting holes in the frame must be used (fig. ),
• Additional electrical bonding to Ground is required for the support structure,
• Refer to the fixing device manufacturer’s installation instructions for preload or torque values.
