Connecting The Mains Cable - Fronius TPS 320i Operating Instructions Manual

Connecting the mains cable

General If no mains cable is connected, a mains cable that is suitable for the connection voltage
must be fitted before commissioning.
A universal strain-relief device for cable diameters from 14 - 16 mm (0.55 - 0.63 in.) is fitted
to the power source.
Strain-relief devices for other cable cross-sections must be designed accordingly.

Cable type for USA / Canada: Extra-hard usage
CAUTION! Risk of injury and material damage due to short circuits.
Short circuits can occur between the phase conductors or between the phase
conductors and the ground conductor unless ferrules are used.
Fit ferrules to all phase conductors in an exposed mains cable as well as the
ground conductor.
NOTE! Mains cables must be connected to devices in compliance with national
standards and guidelines and the work must be carried out by a qualified person.
