interfaces are used in every installation. 
 

(1)

 

Connect the external cables as the single line diagram examples shown. 

NOTE: Universal PCS is built in with RSD transmitter. Please contact POMCube 

for supported sizes of RSD receivers. If the RSD initiation device needs to be 
installed separately according to local code, please choose one of the options 
according to the diagram. 

 

CAUTION: In areas of frequent thunders and lightnings, a Class 2 SPD (Surge 
Protection  Device)  shall  be  installed  in  front  ends  of  both  Solar  and  Grid 
inputs. 

 

CAUTION: On the grid input side of the equipment, a circuit breaker with 
short-circuit protection function or fuse should be installed.
