(2) Confirm that the input PV modules are of the same
specifications and types before connection of DC input;
(3) Connect the DC cables to the inverter’s copper bar
terminals of DC side according to the Table 3-3, as shown in
Figure 3-8 and 3-9. In Table 3-3, CPS SC100KT-O/US-480,
this type of inverter means that the negative pole of DC input
needs to be connected to the earth grounding wire and CPS
SC100KT-OPG/US-480, this type of inverter means that the
positive pole of DC input needs to be connected to the earth
grounding wire.
