and maximum series overcurrent protective device in the combiner box are recommended for
reverse current protection when more than three strings are connected in parallel.
2.2.16 The solar modules are recommended to be installed over a fireproof and insulating roof
covering when installed on a roof.
2.2.17 Module may not be contacted during working.
2.2.18 Modules should be safely fixed on the roof to bear all expected loads, including wind and
snow loads.

Installation Condition

3.1.1 Environment temperature: -40 to 85℃
3.1.2 Operating temperature: -40 to 85℃
3.1.3 Mechanical load on panels (e.g., from wind or snow): wind load less than 2400 Pa/snow
load less than 5400 Pa.
3.1.4 Tilt Angle selection: The installation should be facing north in the southern hemisphere and
facing south in the northern hemisphere.
3.1.5 To maintain the modules' Class C fire rating, the fire class of the roof and building mate-
rials should higher than Class C. The fire rating of this module is valid only when mounted in the
manner specified in the mechanical mounting instructions.
3.1.6 Raise the distance when installation requirement is greater than or equal to 0.3 m. Mod-
ule installation use appropriate installation angle, refer to the following Table 2.

Installation Methods

3.2.1 Bolting
All modules must be securely fastened with at least 4 bolts (Fig. a). For maximum security ag-
ainst strong winds or heavy snow falls, suggestion for all of the mounting holes should be used.

Remark: As for above diagram, the solid red arrows indicate primary bolt positions; dashed green arrows indicate positions where bolts can
be added for additional support.
Bolts are inserted as described in the process below (Fig. b).
1. Place the module on the supporting bars underneath.
2. Insert stainless-steel bolts (M6 or M8) through the holes (use M6 series mounting access-
ories when the size of mounting holes is 7x11.5mm and use M8 series when the size is 9x13
mm) in the frame according to the Fig. a. For maximum security against strong winds and he-
avy snow, all available mounting holes should be used.
3. Secure each bolt to the frame with 2 stainless-steel washers, one on each side of the mo- unting
structure; and screw on either a stainless-steel spring washer or a toothed lock washer. Finally,
secure with a stainless steel nut (M6 or M8).
4. The torque for tightening the nut and bolts recommended 13Nm when the property class of
bolts and nuts is Class 8.8.
