● Cables with high rigidity, such as armored cables, are not recommended as DC
input power cables, because poor contact may be caused by the bending of the
cables.
● Before assembling DC connectors, label the cable polarities correctly to ensure
correct cable connections.
● After crimping the positive and negative metal contacts, pull the DC input
power cables back to ensure that they are connected securely.
● Insert the crimped metal contacts of the positive and negative power cables
into the appropriate positive and negative connectors. Then pull back the DC
input power cables to ensure that they are connected securely.
● Crimp the metal stamping forming contacts using crimping tool H4TC0003
(Amphenol, recommended), H4TC0002 (Amphenol), PV-CZM-22100 (Staubli),
or PV-CZM-19100 (Staubli). When choosing PV-CZM-22100 or PV-CZM-19100,
do not use the locator. Otherwise metal contacts would be damaged.

● The DC voltage measurement range of the multimeter must be at least 1100 V.
● If the voltage is a negative value, the DC input polarity is incorrect and needs correction.
● If the voltage is greater than 1100 V, too many PV modules configured in the same
string. Remove some PV modules.
