1. Risks & safety precautions 

Solar modules generate electricity as soon as they are exposed to light. It is hazardous to touch a module with a voltage 
of 30 volts or more. Each serial or parallel connection of modules increases the voltage or current. By connecting more 
than two solar modules in series, hazardous voltages may occur! 

 

Danger of death due to electric shock! 

Although touch protection is provided in the form of the fully insulated plug contacts, please ensure that 

 

 no electrically conducive parts are inserted into the plugs or sockets when handling the solar modules! 

 

Solar modules and cables are not installed with moisturized male and female connectors! 

 

all works on the cables are undertaken with extreme caution! 

 

high contact voltages may still be present inside the inverter even when the unit is switched off! 

 

as a rule, caution is exercised when performing any work on the inverter and cables! 

Heckert Solar brand modules correspond with Class II. 

 

Risk of death by electric arc!
