General Information

  

The installation of solar modules requires a great degree of skill 
and should only be performed by qualified licensed professionals, 
including, without limitation, licensed contractors and electricians.  
 

 

  

WARNING 

 

All instructions should be read and understood before 
attempting to install, wire, operate, and maintain a 
photovoltaic module.  

 

Contact with electrically active parts of the module such 
as terminals can result in burns, sparks, and lethal shock 
whether the module is connected or disconnected. 

 

The installer assumes the risk of all injury that might 
occur during installation, including, without limitation, the 
risk of electric shock. 

 

PV modules generate DC (direct current) electrical energy 
when exposed to sunlight or other light sources. Even a 
single module produces enough voltage and current, to 
cause shocks and burns if safety precautions are not 
followed. 

 

The shock hazard increases as modules are connected in 
parallel, producing higher current, and as modules are 
connected in series, producing higher voltages. 

 

To avoid the hazard of electric sparks, shock, fire, burns, 
damage and injury: 

 

Work only in dry conditions, with dry modules and dry 
tools. 

 

Do not stand or step on modules. Do not puncture, cut, 
scratch or damage the backsheet of a module. 
Backsheet damage will void a module’s Limited 

Warranty and may cause fire. 

Never use modules with a 

damaged back sheet. 

 

Do not allow children and unauthorized persons near 
the installation or storage site of modules. 

 

Completely ground all modules. 

 

Do not disassemble a module, attempt any repair, open 
the junction box cover, nor remove any parts installed 
by Sanyo. There are no user serviceable parts within 
the module or junction box. 

 

Unauthorized persons - except the qualified licensed 
professional - should not  perform any electrical work, 
including wiring, 

 

Wear suitable clothing, guards, eye protection and 
gloves to prevent you from direct contact with 30 VDC 
or greater. 

 

Wear non-slip gloves and carry modules by the frame 
using both hands. Do not attempt to carry a module by 
yourself. 

 

Do not carry a module by its wires or junction box. 

 

Do not drop anything on the surface of a module. 

 

Ensure all system components are compatible, and 
they do not subject the module to mechanical or 
electrical hazards. 

 

Sparks may occur; do not install modules where 

flammable gases or vapors are present. 

 

Never rest or leave a module unsupported or 
unsecured. 

 

Do not drop modules. 

 

Do not use or install broken modules. 

 

Do not artificially concentrate sunlight on a module. 

 

Do not touch the junction box terminals. 

 

Do not change the wiring of bypass diodes. 

 

Do not touch a PV module unnecessarily. The glass 
surface and frames get hot. There is a risk of burn. 

 

  

CAUTIONS 

 

Use a module for its intended purpose only. 

 

Do not treat the back sheet, frame, or front surface with 
paint or adhesives, to avoid reducing its’ functionality, 
damage, and causing inoperable conditions, and other 
unknown troubles. 

 
GENERAL SAFETY

  

Follow all permissions, installation and inspection 
requirements.  

 

Before installing modules, contact the appropriate authorities 
having jurisdiction to determine permissions, installation and 
inspection requirements, which should be followed.  

 

Electrically ground modules for all systems of any voltage. If 
not otherwise specified, it is recommended that requirements 
of the latest National Electrical Code (USA) or Canadian 
Electric Code (Canada) or other national or international 
electrical standards be followed. Refer to “Earth Ground 
Wiring” section for more information. 

 

Be sure that the building or structure (roof, façade, etc.) where 
the modules are being installed has enough strength to 
support the load of the modules.  

  For modules mounted on roofs, special  structures may be 

required to help provide proper installation support.   

 

Both, roof construction and module installation design have an 
effect on the fire resistance of a building. Improper installation
