1. To fix the wire between the
flat washer and cup washer,
place the cup washer
(concave side up) between
the frame and the wire.
2. Then tighten the bolt
using the toothed nut.
•
Standard modules can be installed in either
landscape or portrait orientations. Refer to
the detailed instructions for further guidance.
Please note that in areas with heavy snowfall (>
2400 Pa) further countermeasures such the use
of additional support bars should be conside-
red to avoid snow loads damaging the lowest
row of modules.
•
In cases where an additional support bar is re-
commended to improve both mechanical sta-
bility and long-term module performance, we
recommend selecting a sufficiently resistant
material. EDF ENR PWT recommends bars with
a minimum thickness of 50mm (1.97 in). The
support bar centerline should be positioned
within 100 mm (3.94 in) of the side frame cen-
terline (slight shifts may be necessary to access
module grounding holes).
•
The load described in this manual corresponds
to test load. For installations complying with IEC
61215-2:2016 and UL 1703, a safety factor of 1.5
should be applied for calculating the equivalent
maximum authorized design loads. Project de-
sign loads depend on construction, applicable
standards, location and local climate. Determi-
nation of the design loads is the responsibility
of the racking suppliers or professional en-
gineers. For detailed information, please follow
local structural code or contact your professio-
nal structural engineer.
6.1
MOUNTING METHOD : BOLTING
•
The mounting method has been qualified by
EDF ENR PWT, as well as certified by VDE and
CSA.
•
Modules should be bolted to support structures
through the mounting holes in the rear frame
flanges only.
•
Each module must be securely fastened at a mi-
nimum of 4 points on two opposite sides.
M8 X 1.25 (5/16”) bolt and nut should be used.
The yield strength of bolt and nut should not be
less than 450 MPa.
•
Tightening torques should be within 17~23 Nm
(12.5~17.0 ft-lbs) for M8 (5/16”) coarse thread
bolts, depending on bolt class.
•
In areas with heavy wind loads, additional
mounting points should be used. The system
designer and the installer are responsible for
calculating the load and ensuring that the sup-
port structure meets the requirements.
