modules directly to sunlight for a long time.
4.2.5
Do not change the configuration of the bypass diodes. Do not disassemble the modules.
4.2.6
Do not contact with module surface when the module is wet unless to clean the modules, please
following requirements mentioned in this manual when cleaning.
4.3 Handling safety
4.3.1
Do not open the box until it reaches the installation location. Keep the package in a ventilated and dry
place.
4.3.2
PV modules Unpacking Please refer to Unpacking manual of standard package of Sunerg Solar
photovoltaic modules. During all handling procedures, make sure that the modules are not subject to large
vibrations, that the modules fall to the floor or that objects fall on the module, as this will Damage to the
modules or solar cell. Special care must be taken not to bump, scrape, or press against the back of the module.
Keep children and unauthorized person away from the modules while transporting or installing them. Improper
transportation or placing may lead to glass breakage or power loss of the modules, resulting in the loss of the
use value of modules.
4.3.3
Handle modules with care, lift and put down modules gently. It is forbidden to carry or lift the modules
by grabbing the junction box or cables.
Two or more people must hold the module with both hands.
4.3.4
Do not step on, stand or sit on the module, which can damage the module and create a risk to people.
4.3.5
Do not place any heavy objects on the front or back of the module, and do not place the module on a
sharp object surface.
4.4 Installation safety
4.4.1
Abide by the safety regulations for all other modules used in the PV system, including wiring and cables,
connectors, controllers, inverters, storage batteries, etc., and use suitable equipment, connectors, wiring and
mounting system for a PV system. If the PV system is used in storage batteries, the configuration with the
modules should follow the advice of the storage batteries manufacturer. The same size, the same specifications
of the model can be connected in series.
4.4.2
Do not install or handle the modules when they are wet or during strong wind. Keep the junction box’s
cover closed.
4.4.3
Modules of the glass with the role of protection modules, unreasonable operation will cause glass broken.
Damaged modules have the risk of electric shock and fire, such modules can not be repaired or maintained,
should be replaced immediately.
4.4.4
When exposed to direct sunlight, one individual solar module may generate DC voltages greater than 30
volts. It is extremely dangerous to contact it.
4.4.5
To reduce the risk of electric shock or burning, you can install modules with opaque material on the
surface of the module. The mounting of the array of modules must be carried out with an isolating solar
installation. Do not wear metal rings, watches, earrings and other metal accessories when installing or
servicing PV systems. Do not touch the electrical parts of the module directly by hand. Use an insulating tool
to make electrical connections and keep the tool dry.
4.4.6
The triangle hole punched on the backside frame of the module is the drainage hole which cannot be
blocked.
4.4.7
The maximum system voltage indicated in the rating label is 1500 V. During the system Installation, the
maximum open circuit voltage in series cannot exceed the maximum system voltage.
