5.4.2 DC connection

Step 1: Assemble DC cable to connector at the inverter side. See “5.4.1 DC Input

Wiring”.

Step 2: Disconnect DC and AC circuit breakers.
Step 3: Check connection cable of one PV array string for correct polarity and that

the maximum input open circuit voltage does not exceed 520V.

Step 4: Measure DC voltage between positive terminal of the PV string and Earth

and DC voltage between negative terminal of the PV string and Earth. If the two voltages
are constant and not zero, there is an insulation failure somewhere in this PV string.
