dissipation.  
3. Do not drop lead wire stub or screw 
in the inverter.  Otherwise it may 
damage the inverter! 
1.1.3 During wiring:   
Danger Danger 
1. Operation shall be performed by the

Otherwise there will be danger of electric 
shock! 
2. There shall be circuit breaker 
between the inverter and power supply.  
Otherwise, there may be fire! 
3. Make sure the power is disconnected 
prior to the connection.    Otherwise there
