8.4.2
Overvoltage category
The product can be used in grids of overvoltage category III or lower in accordance with IEC 60664-1. That means
that the product can be permanently connected to the grid-connection point of a building. In case of installations with
long outdoor cabling routes, additional measures to reduce overvoltage category IV to overvoltage category III are
required (see the Technical Information "Overvoltage Protection" at www.SMA-Solar.com).
8.4.3
AC cable requirements
☐ Conductor type: aluminum or copper wire
☐ The conductors must be solid, stranded or fine-stranded. When using fine-stranded wire, bootlace ferrules must be
used.
☐ Conductor cross-section: 16 mm² to 95 mm²
☐ External diameter: 35 mm to 48 mm
☐ Insulation stripping length: 30 mm
☐ Sheath stripping length: ≤ 375 mm

8.4.4
Network cable requirements
The cable length and quality affect the quality of the signal. Observe the following cable requirements:
☐ Cable type: 100BaseTx
☐ Cable category: minimum CAT5e
☐ Plug type: RJ45 of Cat5, Cat5e or higher
☐ Shielding: SF/UTP, S/UTP, SF/FTP or S/FTP
☐ Number of insulated conductor pairs and insulated conductor cross-section: at least 2 x 2 x 0.22 mm²
☐ Maximum cable length between 2 nodes when using patch cables: 50 m
☐ Maximum cable length between 2 nodes when using installation cables: 100 m
☐ UV-resistant for outdoor use.
8.4.5
Battery data cable requirements
The cable length and quality affect the quality of the signal. Observe the following cable requirements:
☐ Cable type: 100BaseTx
☐ Cable category: minimum CAT5e
☐ Plug type: RJ45 of Cat5, Cat5e or higher
☐ Shielding: SF/UTP, S/UTP, SF/FTP or S/FTP
☐ Maximum cable length between 2 nodes when using patch cables: 50 m
☐ UV-resistant for outdoor use.
