Regular safety
DualSun module is considered to be in compliance with IEC61730 only when the module is
mounted in the manner specified by the mounting instructions below.
When the module is installed on roof, it is necessary to take the overall fire rating of the finished
structure as well as later overall maintenance into account. The roofing PV system shall be installed
after assessment by construction experts or engineers and with official analysis results for the entire
structure. It shall be proved capable of supporting extra system bracket pressure, including PV
module weight.
For your safety, please do not work on the roof without safety protective measures which include
but not limited to fall protection, ladder or stair and personal protective articles.
For your safety, please do not install or handle modules in unfavorable conditions including but
not limited to strong wind or gust, damp or sandy roofs.
