5.7.2 Connecting Cables to Amphenol Helios H4 Connectors

Specification Requirements
Cables with high rigidity, such as armored cables, are not recommended, because
poor contact may be caused by the bending of cables.
Use the Amphenol Helios H4 connectors delivered with the solar inverter. If the PV
connectors are lost or damaged, purchase the connectors of the same model. The
device damage caused by incompatible PV connectors is beyond the warranty
scope.
Procedure
Step 1 Prepare the DC input power cables.
Step 2 Crimp positive and negative metal contacts.
Step 3 Insert the contacts into the corresponding positive and negative connectors.
