3. On the DC subdistribution, remove the protection foil from the cable harnesses for connection
of the PV strings.
4. If inline fuse connectors are used, connect the inline fuse connectors to the assembled DC
connectors of the PV module string cables (see installation manual "IFCON Inline Fuse
Connector Set16").
5. Connect the PV module string cables PV+ to the DC subdistribution:
• Connect the assembled DC connectors of the PV module string cables (PV+) to the string
cable harnesses (PV+) of the DC subdistribution:
– If using inline fuse connectors, plug the inline fuse connectors of the PV module string
cables (PV+) into the string cable harness (PV+) of the DC subdistribution.
☑ The inline fuse connectors snap into place.
– If no inline fuse connectors are used, plug the assembled DC connectors of the PV
module string cables (PV+) into the DC connectors of the string harness (PV+) in the
DC subdistribution.
☑ The DC connectors snap into place.
6. Connect the string cables PV module PV‒ to the DC subdistribution:
• Connect the assembled DC connectors of the PV module string cables (PV‒) to the string
cable harness (PV‒) of the DC subdistribution:
– If using inline fuse connectors, plug the inline fuse connectors of the PV module string
cables (PV‒) into the string cable harness (PV‒) of the DC subdistribution.
☑ The inline fuse connectors snap into place.
– If no inline fuse connectors are used, plug the assembled DC connectors of the PV
module string cables (PV‒) into the DC connectors of the string cable harness (PV‒)
in the DC subdistribution.
☑ The DC connectors snap into place.
7. Ensure that all DC connectors are securely connected.
8. Close any unused terminals on the string cable harnesses of the DC subdistribution with
protective caps of the SUNCLIX plug-in system for DC connectors. This will seal the DC
connectors.
9. Fasten the string cables to the external cable support rail.
