5.3 Installing DC Input Power Cables 
Connect the SUN2000 to PV arrays over DC input power cables 
Prerequisites 
 
PV modules generate electric energy when exposed to sunlight and can create an 
electrical shock hazard. Therefore, when connecting DC input power cables, cover PV 
modules by using opaque cloth. 
 
Before performing electrical connections, ensure that voltages of the DC cables should 
be within the safe voltage range, that is, lower than 60 V DC, and the DC SWITCH is 
OFF. Otherwise, the high voltage may result in fatal danger. 
 
 
Ensure that the following conditions are met. Otherwise, fire accident may occur.
