Figure 5-16 Preparing positive and negative connectors (using metal stamping
forming contacts)
(1) Positive metal contact (stamping forming) (2) Negative metal contact (stamping forming)
(3) Positive connector (4) Negative connector
After the positive and negative metal terminals snap into place, pull the DC input
power cables back to ensure that they are connected securely.
Step 2 Use a multimeter to measure the DC voltage between the positive and negative of
the PV string and
conrm the string polarity.
The DC voltage measurement range of the multimeter must be at least 1100 V.
