Avoid  partial  shading  of  PV  modules  for  a  long 

period  of  time,  otherwise  the  temperature  of  the 

shaded  module  may  rise  due  to  hot  spot  effect, 

burning the module and causing fire hazard in severe 

cases.

 

 

For PV modules used in deserts or windy  and sandy 

areas, it is recommended to use connector dust caps 

before installation or take other measures to prevent 

sand  and  dust  from  entering  the  connectors, 

otherwise  it  may  cause  insertion  problems  or 

electrical safety hazards.

 

 

3.2

 

Operation safety measures 

 

 

Avoid  package  damaging  and  falling  during 

transportation and storage. Ensure the  packing cases 

are well ventilated, water-proof and  dry. After the 

arrival, carefully open the outer package and prevent 

scratches and bumps of PV modules. When stacking 

PV 

modules, 

strictly 

follow 

the 

stacking 

requirements in chapter 4.3.

 

 

 

Avoid  impact  or  scratches  on  any  part  of  the  PV 

module,  otherwise  the  reliability  and  safety  of  the 

PV module will be affected; standing or walking on 

the  PV  module  is  prohibited;  at  the  same  time,  in 

order to avoid glass damage, it is forbidden  to apply 

excessive load or distorted PV modules.

 

 

 

Do not install or carry PV modules by one person. 

It is forbidden to pick up, drag, or move PV modules 

by  grabbing  the  junction  box  (including the  box 

body,  cables,  and  connectors);  when placing  a  PV 

module  on  a  flat  surface,  it  must  be  operated 

carefully and be aware of bumps in the corners.

 

 

 

When installing or repairing the PV system, do not

 

wear  any  metal  accessories  to  avoid  the  risk  of 

electric shock; if it is installed far above the ground, 

please wear a seat belt. 

 

 

When operating PV modules in the sun, please use 

insulated  tools,  and  wear  rubber  gloves  and 

protective  clothing.  At  the  same  time,  in  order  to 

avoid  the  risk  of  arc  and  electric  shock,  do  not 

directly  touch  the  junction  box  and  the  end  of  the 

output cable (connector) with bare hands.

 

 

 

For  electrical  connection,  choose  a  dry  and  weak-

light morning or evening; or use opaque materials to 

completely cover the surface of the PV modules to 

prevent current generation.

 

 

 

A certain distance between the PV module and the 

installation  surface  should  be  kept  to  prevent  the 

installation surface from touching the junction box.

 

 

 

When  installing  on  the  roof,  comply  with  the  fire 

protection  requirements  of  the  building.  It  is 

recommended to install PV modules on a fireproof 

and  insulated  roof  covering,  and  ensure  adequate 

ventilation  between  the  PV  modules  and  the 

installation surface. In order to ensure the  fire rating 

on  the  roof,  the  minimum  distance  between  the 

frame  of  the  PV  module  and  the  roof  surface  is 

10cm.

 

 

 

The connector must be fully mated when wiring. If 

the  cable  is  too  long,  it  is  recommended  to  fix  the 

cable to the rack system with a UV-resistant nylon 

cable  tie.  When  fixing  the  cable  to  the  rack,  the 

bending radius of the cable should not be less than 

48mm.

 

 

 

Avoid  directly  exposing  cables  and  connectors  to 

sunlight. Please use anti-UV cables.
