User Manual
Use the Amphenol Helios H4 PV connectors supplied with the SUN2000. If the PV
connectors are lost or damaged, purchase the connectors of the same model. The device
damage caused by incompatible PV connectors is not covered under any warranty.

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 1080 V, too many PV modules configured in the same string. Remove
some PV modules.
