3.3 Electric performance safety
PV products will produce DC in the sunlight, so there may be electric shock or
burning when touching module connecting line metals. 30V DC voltage or higher
voltage can be fatal.
In case of no connected load or external circuits, modules can also produce
voltage. Please use insulation tools and wear rubber gloves when operating
modules in the sunlight.
PV modules doe not have switch. PV modules can only stop work when they are
kept from sunlight or covered by cloth, hard board or light-proof materials or when
front side of modules are placed on smooth and flat surfaces.
To avoid electric arc or electric shock hazards, please do not break down electric
connection in loaded conditions. Wrong connections will also lead to electric arc or
shock. Keep connectors dry and clean and make sure that they are in good
working condition. Do not insert other metals into the connectors or carry out
electric connection by whatever means.
Snow and water in surrounding environments will intensify light reflection and
lead to increase of current and output power. And module voltage and power will
increase under low temperature.
If module glass or packaging materials are damaged, please wear personal
protective articles and isolate modules from the circuit.
Working is only allowed in dry conditions by means of dry tools. Do not operate
when modules are wet unless you wear the proper electric shock protection
device. Please operate following the cleaning requirements in this manual when
cleaning modules.
3.4 Operation safety
Do not open GRUPPOSTG Package in transportation and storage process unless
the modules arrive at the installation site.
Do not damage the package and do not make packaged modules on pallet fall
directly.
Do not exceed the highest layer limit indicated on the packaging carton when
piling modules up. Put packaging carton in the ventilated, rain-proof and dry
places before unpacking of modules.
Open GRUPPOSTG’s packaging carton following unpacking instructions.
Do not hold the connecting box or wires to lift the entire module in any cases.
Do not stand or walk on modules.
