Keep  children  well  away  from  the  system  while  transporting  and  installing 
mechanical and electrical components.   

 

Completely cover all modules with an opaque material during installation to 
prevent electricity from being generated. 

Do  not  wear  metallic  rings,  watchbands,  ear,  nose,  or  lip  rings  or  other 
metallic devices while installing or troubleshooting photovoltaic systems. 

Use appropriate safety equipment (insulated tools, insulating gloves, etc.) 
approved for use on electrical installations. 

 

Observe the instructions and safety precautions for all other components used 
in the system, including wiring and cables, connectors, DC-breakers, mounting 
hardware, inverters, etc.   

 

Use only equipment, connectors, wiring and mounting hardware suitable for 
use in a photovoltaic system.   

 

Always use the same type of module within a particular photovoltaic system.   

 

Under  normal  operating  conditions,  PV  modules  will  produce  currents  and 
voltages that are different from those listed in the data sheets. The values in the 
module data sheets are collected under very specific circumstances known as 
Standard Test Conditions.   

 

Short-circuit current and open-circuit voltages should be multiplied by a factor 
of 1.25 when determining component voltage ratings, conductor ampacity, 
fuse sizes and size of controls connected to the module or system output. An 
additional  multiplying  factor  of  125  percent  (80  percent  de-rating)  may  be 
applicable. 

3.2

 

General installation notes 

 

The junction box has a breather port which must be mounted facing downward 
and cannot be exposed to the rain. The junction box should be on the higher 
side  of  the  module  when  it  is  mounted  in  order  to  orient  the  breather  port 
correctly.   

 

Do not lift the module by grasping module's junction box or electrical leads.   

 

Do not stand or step on the module.   

 

Do not drop the module or allow objects to fall on the module.   

 

Do not place any heavy objects on the module.   

 

Do not scratch the glass surface. 

 

Prior to installation, do not store modules outdoors or in a damp environment. 

 

Inappropriate transport and installation may damage the module glass. 

3.3

 

Fire rating 

 

The  fire  rating  for  this  module  is  only  valid  when  the  product  is  installed  as 
specified in the mechanical mounting instructions in this document. 

 

For system fire rating, it should be evaluated among with the roof cover and 
mounting.  Consult  your  local  authority  for  guidelines  and  requirements  for 
building or structural fire safety. Roof constructions and installations may affect 
the  fire  safety  of  a  building;  improper  installation may  create  hazards  in  the
