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.
Additionally required material (not included in the scope of delivery):
☐ One battery communication cable for the communication between inverter and battery
☐ In battery-backup systems with automatic transfer switch: one communication cable between
inverter and automatic transfer switch
☐ If cables are routed in a conduit: conduit (trade size: 21 mm (0.75 in) or smaller with suitable
reducer bush)
☐ If cables are routed in a conduit: UL-listed raintight or liquidtight conduit fitting (trade size:
21 mm (0.75 in) or smaller with suitable reducer bush)
