Procedure
Step 1 Connect the DC power cable.
Use the positive and negative Staubli MC4 metal terminals and DC connectors
supplied with the SUN2000. Using incompatible positive and negative metal
terminals and DC connectors may result in serious consequences. The caused
device damage is not covered under warranty.
● You are advised to use the PV-CZM-22100 (Staubli) crimping tool and do not
use it with the positioning block. Otherwise, the metal terminals may be
damaged.
● The PV-MS (Staubli) or PV-MS-HZ (Staubli) open-end wrench is recommended.
● 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 the positive and negative connectors snap into place, pull the DC input
cables back to ensure that they are connected securely.
