Connecting The Data Cable Of The Battery And Communication Cable Of The Automatic Transfer Switch - SMA SBS3.7-10 Operating Manual

6 Electrical Connection
Procedure:
1.
Danger to life due to electric shock
• Disconnect the inverter from all voltage sources (see Section 9, page 72).
2. Remove the sealing plugs from the network connection opening on the inverter.
3. Insert the cable gland into the opening and screw the counter nut on from the inside.
4. Cut into the two-hole cable support sleeve with a box cutter. This will push the cable into the
grommet.
5. Press the cable support sleeve into the two-hole cable gland.
6. Insert the cable into the enclosure opening of the two-hole cable support sleeve.
7. Lead one end of each network cable into the inverter.
8. When using a self-assembly network cable, assemble the RJ45 connector and connect to the
network cable (see connector documentation).
9. Put the network plug of each cable into one of the
network sockets of the communication assembly.
10. Ensure that the network connector is securely in place by pulling slightly on each cable.
11. If the inverter is installed outdoors, install overvoltage protection.
12. If you would like to establish a direct connection, connect the other end of the network cable
directly to the end device.
13. If you would like to integrate the inverter into a local network, connect the other end of the
network cable to the local network (e.g. via a router).
6.5 Connecting the Data Cable of the Battery and
Communication Cable of the Automatic Transfer
Switch
Connect the communication cable of each battery and, in battery-backup systems, the
communication cable of the automatic transfer switch as described in the following.
Communication between Inverter and Battery
• Communication between the inverter and the battery takes place via the battery
communication cable via CAN bus.
