15. If no additional grounding is to be connected,
reattach the DC protective cover. Tighten all four
screws with an Allen key (AF 3) in the order 1 to
4 (torque: 3.5 Nm (31 in-lb)).
6.5 Connecting the Inverter to the Network
Cable requirements:
The cable length and quality affect the quality of the signal. Observe the following cable
requirements.
☐ Cable type: 100BaseTx
SMA recommends cable type "SMA COMCAB-OUTxxx" for outdoor use and cable type
"SMA COMCAB-INxxx" for indoor use, available in lengths xxx = 100 m (328 ft), 200 m
(656 ft), 500 m (1,640 ft), 1,000 m (3,281 ft)
☐ Cable category: Cat5, Cat5e, Cat6, Cat6a or Cat7
☐ Plug type: RJ45 of Cat5, Cat5e, Cat6 or Cat6a
☐ 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 (2 x 2 x 24 AWG)
☐ Maximum cable length between two nodes when using patch cables: 50 m (164 ft)
☐ Maximum cable length between two nodes when using installation cables: 100 m (328 ft)
☐ UV-resistant for outdoor use
Procedure:
1.
Danger to life due to electric shock
• Disconnect the inverter from all voltage sources (see Section 9, page 41).
2. Connect one end of the network cable to the inverter:
• Remove the filler plugs from the network connection opening on the inverter.
• Attach the conduit to the opening.
• Lead the network cable through the conduit into the interior of the inverter.
• Release the screw of the display far enough to allow the display to be flipped up.
• Flip the display up until it snaps into place.
• Insert the network cable into one of the network jacks of the Webconnect Data Module.
• Flip the display down and fasten the display screw hand-tight.
