specified maximum system voltage. The voltage is proportional to the number of series. In case of
parallel connection, please be sure to take proper measure (e.g. fuse for protection of module and
cable from over current, and/or blocking diode for prevention of unbalanced strings voltage) to
block the reverse current flow. The current may easily flow in a reverse direction.
< INSTALLATION SAFETY>
1.
During transportation or storage, unless you reach the installation site, otherwise, do not open the
package of the modules.
2.
Please protect the modules’ package. When loading or unloading the modules, please handle with
care. Do not drop the packed pallet of modules down directly.
3.
Before open the modules’ package, store the modules in ventilated and dry place.
4.
When opening the modules’ package with knife, be careful not scratching the module.
5.
Do not lift the whole module by grabbing the terminal box or cable in any sense.
6.
Modules are heavy. Handle with care. Do not drop PV modules far above ground. Do not drop one
module down on another module.
7.
Do not stand or step on the module. Do not pass by stepping on the module especially when
installing, maintain and washing the modules.
8.
Do not hit or put excessive load on the glass or back sheet. Do not allow objects fall down on the
module.
9.
Do not cause an excessive load on the surface of PV module or twist the frame.
10.
Do not scratch or hit at the back sheet. Do not hit on the terminal box or do not pull the cables.
Please notice the ground condition when the module is placed horizontally with back sheet faced
down.
11.
Do not try to unpick the module, remove any parts or the nameplate of the module.
12.
Do not brush oil paint or any other adhesive on the surface of the module. Do not scratch the
insulation coating of the frame (except for grounding connection). It may cause corrosion of the
frame or compromise the framework strength.
13.
Do not drill holes in the frame. It may compromise the frame strength and cause corrosion of the
frame.
14.
Do not repair glass, back sheet or other broken part of the module.
15.
Please install with dry tools in dry condition. Do not operate when the module is wet, unless wear
proper equipment against electrical shock.
16.
Do not grab the PV module at only one side. The frame may bend. Grab the PV module at two
sides facing each other.
17.
Do not touch the PV module with bare hands. The frame of PV module has sharp edges and may
cause injury.
18.
Do not scratch the output cable or bend it with force. The insulation of output cable can break and
may result in electricity leakage or shock.
19.
Do not try artificially to concentrate sunlight on the PV module. Never touch terminal box or the
end of output cables with bare hands when the PV module is irradiated. Cover the surface of PV
module with cloth or other suitable sufficiently opaque material to isolate the PV module from
incident light and handle the wires with rubber-gloved hands to avoid electric shock.
20.
Always wear protective head gear, insulating gloves and safety shoes (with rubber soles).
21.
Do not touch the PV module unnecessarily during installation. The glass surface and the frames get
hot. There is a risk of burn, or you may collapse because of electric shock.
22.
Do not work under rain, snow or windy conditions.
