Installation Manual for DualSun PV Modules
3.3
Electric performance safety
The application level of DualSun module is Application Class A
, w
hich can be used in systems
operating at greater than 50 V DC or 240 W, where general contact access is anticipated;
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 do 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 DualSun 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 DualSun
’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.
Do not pile one module onto another.
To avoid glass damage, do not put heavy objects on module glass.
Be careful when placing modules on a surface and at corners in particular.
Do not try to unpack the module or remove nameplate or parts of modules.
Do not paint surface of modules or apply any other glues.
Do not damage, grad or scratch back film of modules.
Do not drill frame of modules, which may reduce frame loading capacity or lead to frame
corrosion.
Do not scratch anodic coating of aluminum alloy frame except for grounding connection.
Scratch may lead to frame corrosion and reduce frame loading capacity.
