voltage at the DC position. The multimeter must have a DC voltage range of at least
600 V. If the voltage is a negative value, the DC input polarity is incorrect and needs
correction. If the voltage is greater than 600 V, too many PV modules are ÑÊĒªñà to

Before performing
Step 2
, ensure that the DC switch is set to OFF.
Step 2 Insert the positive and negative connectors into corresponding DC input terminals
on the SUN2000.

After the positive and negative connectors snap into place, pull the DC input
power cables back to ensure that they are connected securely.
