5.3 Installing AC Output Power Cables 

Connect the SUN2000 to the AC power distribution frame (PDF) or power grid using AC 
output power cables. 

Prerequisites 

An independent three-phase circuit breaker must be installed on the AC side of each 
SUN2000 to ensure that the SUN2000s can be safely disconnected from the power grid. See 

10 Technical Specifications

 to select the circuit breaker of the appropriate specifications. 

 

 

 

Do not install a single circuit breaker for several SUN2000s. 

 

Do not connect loads between the SUN2000 and circuit breaker. 

Context 

 

Outdoor copper-core cables are recommended. 

Table 5-1

 describes the specifications.
