REC Installation Manual - REC Alpha Panels - UL 6
Rev G . Ref: PMIM
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
The REC solar panels covered by this manual can be installed utilizing the four mounting holes ( x . mm) on the underside of the panel (fig. & )
in conjunction with a device, e.g., screws, lockbolts or structural blind fasteners, with specifications suitable for the installation (fig. ).
Installing the REC Alpha & Alpha Series solar panels using the mounting holes has been found to comply with IEC & UL requirements
for downward pressure,e.g., snow, of up to Pa ( Pa design load
*
) and upward pressure,e.g., wind, of up to Pa ( Pa design load
*
)
according to the following instructions (
*
design loads apply a safety factor of . to the stated test load, e.g., test load Pa / . = Pa design load).
When installing using mounting holes, the frame and panel edge of each panel must be supported by two rails 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,
• REC modules must be secured with a torque between - Nm (- lbf/in). Refer to the fixing device manufacturer’s installation
instructions for preload or torque values.

CAUTION
The product warranty will be voided if additional holes are made in the frame. All fixing and fastening materials must be corrosion resistant.
