3.3 Electrical Performance Safety
Photovoltaic Modules can produce DC electricity when exposed to light and therefore can produce an
electrical shock or bum. DC voltage of 30 Volts or higher is potentially lethal.
Modules produce voltage even when not connected to an electrical circuit or load. Please use insulated tools
and rubber gloves when working with Modules in sunlight.
Modules have no on/off switch. Modules can be rendered inoperative only by removing them from sunlight,
or by fully covering their front surface with cloth, cardboard, or other completely opaque material, or by
working with Modules face down on a smooth, flat surface.
In order to avoid arcs and electrical shock, please do not disconnect electrical connections under load. Faulty
connections can also result in arcs and electrical shock. So please keep connectors dry and clean, and ensure
that they are in proper working condition. Never insert metal objects into the connector, or modify them in
any way in order to secure an electrical connection.
Also in order to avoid the sand or water vapor entering which may cause the connection and safety issue,
the modules need to be installed and connected to the combiner box once they are taken out from the
carton box; keep the connectors dry and clean during the installing. Note that the pollution from sand, dust
and water will result in arcs and electrical shock of connectors We suggest the customers add rubber
connector covers as the protection method specific to the area with heavy dust seaside with higher salinity
or the serious polluted areas.
Reflection from snow or water can increase sunlight and therefore boost currant and power. In addition,
colder temperatures can substantially increase voltage and power.
If the glass or other material is damaged, please wear personal protection equipment and separated the
Modules from the circuit.
Work only under dry conditions, and use only dry tools. Do not handle Modules when they are wet unless
wearing appropriate protective equipment. If you need to clean the Modules, please follow the cleaning
requirements mentioned in the manual.
3.4 Operating Safety
Do not open packages of Xtremesolar Modules during transportation and storing until they are ready to be
installed.
At the same time please protect the package from damage. Do not make the pallets of Modules falling over
directly.
