To guarantee roof fire rating, the distance between module frame and roof surface must be
≥10cm. (4in)
Adopt proper module accessories such as fuse, circuit breaker and grounding connector
according to local regulations.
Please do not apply modules in where exposed inflammable gases are nearby.
2. Installation
2.1 Installation Safety
① Huasun modules have been qualified for Class II.
② The modules are not suitable for space environments, also not suitable for particularly
harsh environments such as offshore without specially protected.
③ Always wear protective head gear, insulating gloves and safety shoes (with rubber
soles).
④ Never disconnect electrical connections or unplug connectors while the circuit is under
load.
⑤ Contact with electrically active parts of the modules, such as terminals, can result in
burns, sparks and lethal shock whether or not the module is connected.
⑥ Do not touch the PV module unnecessarily during installation. The glass surface and
the frame may be hot; there is a risk of burns and electric shock.
⑦ Do not work in the rain, snow or in windy conditions.
⑧ Avoid exposing cables and connectors to direct sunlight and scratches or cuts in order
to prevent insulation degradation.
⑨ Use only insulated tools that are approved for working on electrical installations.
⑩ Keep children well away from the system while transporting and installing mechanical
and electrical components.
11 Completely cover the module with an opaque material during installation to prevent
electricity from being generated.
12 Do not wear metallic rings, watchbands, earrings, nose rings, lip rings or other metallic
objects while installing or troubleshooting photovoltaic systems.
13 Follow the safety regulations (e.g., safety rules for working on electrical power plant
stations) of your regions and for all other system components, including wires and cables,
connectors, charging regulators, inverters, storage batteries, rechargeable batteries, etc.
14 Under normal conditions, a photovoltaic module is likely to experience conditions that
produce more current and/or voltage than reported at standard test conditions. Accordingly,
the values of Isc and Voc marked on this module should be multiplied by a factor of 1.25
when determining component voltage ratings, conductor current ratings, minimum factor of
fuse sizes, and size of controls connected to the PV output.
15 Only use same connectors to connect modules to form a string, or connect to another
device. Removing the connectors will void the warranty.
