SAFETY
The instructions related to the safety indicated in the following are for preventing unexpected danger or
damage in advance by safely and exactly using the product.
DANGER
Non-compliance of the instructions may immediately cause serious injury or death.
WARNING
Non-compliance of the instructions may cause death or serious injury to the user.
CAUTION
Non-compliance of the instructions may cause injury or property damage to the user.
DANGER
Do not contact electrically active parts of the panel, such as terminals, without appropriate safety gear. Contact may result in lethal spark or electric shock.
Do not use or install if the module is broken or torn. Failure to comply may result in electric shock.
WARNING
Perform all work in dry conditions and use only dry tools. Do
not handle wet panels without appropriate protection equipment. Failure to comply may result in accident or death.
Damaged modules must be treated with safety protection equipment. Failure to comply may result in serious bodily injury or death.
Do not approach the damaged or broken module unless you are an authorized or qualified expert. Failure to comply may result in serious bodily injury or death.
No electrical parts like cables are located after installation between laminate and mounting structure.
Do Not reconnect or repair junction box cable. It may occur spark or electric shock.
Do not bending junction box's cable. While under stress, it may occur module damage. Cable bending radius should be more than 4 times the cable diameter, at least.
CAUTION
Use proper equipment, connectors, wires and buttresses for the installation of the module. Failure to comply may result in product damage, product failure or bodily injury.
Installation during rain, heavy wind or snowy day may result in bodily injury or death.
Holes in the frame or glass of the module may decrease the strength of the frame or break the glass.
03
Do not touch the glass surface or frame of the solar module after installation of the module. It may result in injury or death.
Heavy objects must be kept off of the solar module.
Do not stand on or step on the module. Do not drop the module. Failure to comply may result in product damage, product failure or bodily injury.
Do not scratch the coating surface of the frame.
Scratches may decrease the total solar output due to corrosion of the frame.
Do not artificially concentrate sunlight on the solar module surface. Failure to comply may result in product damage or failure.
Do not apply a shock to the junction box of the module or pull the cable. Do not remove the labels attached to the module. Failure to comply may result in damage of the product.
If the installing modules on curved surface, (e. g. arch type), as shown in the below picture, do not forcefully modify the module in the installation when connecting it with the structure. Only install the module in the place where the structure for the panels has been properly set up. An improper structure may cause deformation of the panels. Panels may also be damaged by unapproved installation methods such as the use of a crane.

BEFORE & AFTER INSTALLATION
Before Installation
Please carefully read this manual before installation.
•Solar module installation and maintenance must be performed by qualified and authorized installer.
•All installation instructions should be read and understood before performing any installation.
•Do not touch the solar module with bare hands. It may result in a burn or injury.
•Do not disassemble the solar module.
•After installation or repair, check that the solar module are operating properly.
•In the event that the currently used solar module or parts have been replaced the newly replaced module and parts must have the same model name and parts as the previously installed solar module.
•Do not let anyone approach the solar module who has little knowledge of solar modules or on the measures to take when solar modules are damaged in order to avoid the risk of injury or electrical shock.
•Secure all necessary permits and licenses to install the solar modules.
•Do not locate the solar module horizontally, as this may cause dirt or white efflorescence(glass deformation).
•Panels are not intended for use indoors or on moving vehicles of any kind.
•Industry standard rated specifications are made at conditions of 1000W/m2 irradiance and 25°C (77°F) solar cell temperature. Colder temperatures may substantially increase voltage and power.
•Keep the solar module and system away from children at all times.
•Keep the module packed in the carton until the time of installation.
•Keep flammable gasses away from the installation site.
•Do not work alone. Please work as part of a team of two or more people.
•Safety harness use is strongly recommended for installation.
•Be careful not to damage the cable when using a tool such as a knife to remove the cable tie that fixes the junction box cable.
•Partial shadowing may substantially reduce panel and system output and may be the reason for the damage of solar module.
•Care must be taken to avoid low tilt angles which may cause dirt to buildup on the glass against the frame edge.
•Dirt build-up on the surface of the panel may cause active solar cells to be shaded and electrical performance to be impaired.
After Installation
•Plug in the connector tightly and ensure that the wiring properly works.
•Conduct periodic inspection of the panels for damage to front glass, back sheet, frame, junction box, or external electrical connections.
•Check electrical connections for loose connections and corrosion.
•PV panels can operate effectively without ever being washed, although removal of dirt from the front glass can increase output.
•Water, ethanol or a conventional glass cleanser with a micro-fiber cloth can be used for regular washing or rinsing of the front glass to remove dust, dirt or other deposits.
•Do not use ground water containing calcium carbonate components when cleaning glass.
•Aggressive and abrasive cleansers or chemicals such as alkali chemicals including ammonia based solution should not be used on cleaning the module.
•Always keep the back surface of the panel free from any foreign objects or structural elements which could come into contact with the panel, especially when the panel is under mechanical load.
•Deposits of foreign material on the frame surface can be cleaned by using a wet sponge or cloth and dried in air or by using a clean chamois.
•Perform the wiring work by connecting the connector and wires to the stand away from the roof or ground.
•Do not use any kind of oil or lubricant on the module's any parts, It can defect the PV Module.
