Distance between outer edge of module and middle of the clamp; consider further details below.
Loads according to IEC 61215-2:2016 and UL 61730.
Test procedure according to IEC 61215-2:2016 and UL 61730. Loads for these mounting options do not fulfill the
requirements of the standards.
Rails must not be under the junction box.

REQUIREMENTS
All
The loads in the table are related to the mechanical stability of the solar modules. The mechanical
stability of the mounting system including clamps has to be evaluated by the system supplier. The
listed test load values have been determined with the following clamp parameters: clamp width =
40 mm and clamp depth = 10 mm.
The system installer is responsible for the determination of location-specific load requirements.
Ensure, that the connection cables of the junction box do not run between laminate and mounting
rails.
Modules bend under load. Therefore, sharp objects (e.g. screws, ballast stones, rail ends, rails
with burrs or sharp corners) must not be placed near the module backside so as not to touch the
laminate under load.
Ensure that the junction boxes do not touch the mounting structure (e.g. shorts rails, ballast, etc.)
or the rooftop under load. Clamps or insertion profiles etc. must not touch the glass (even under
load).
Unbalanced loads (e.g. snow overhangs, snowdrifts) which result in locally significantly increased
loads must be removed or avoided by technical measures.
CL1a, CL2a, CL3,
FB1, FB2
Ensure that module frame is fixed directly on the rail of the substructure (no spacer allowed
between the module and substructure).
CL1b
Using of short mounting rails are permissible, if they overlap with the module less than 210 mm.
Maintain a minimum distance (clearance) of ≥ 35 mm between frame bottom edge and roof top or
ballast.
CL1b, CL2b, CL3, FB2
Minimum support depth of 15 mm is required on the back side of the module.
CL5
Minimum required support depth on the module backside is 10 mm on long frame side and 15 mm
on short frame side.
IP1, IP2
Ensure minimum support depth of 15 mm on the backside and 10 mm on the front side of the
module.
FB1, FB2
Use M8 corrosion-proof screws and washers (diameter ≥ 15.8 mm) for mounting slots (Detail A,
Fig.1). Mounting screws and washers should have the same material properties.
