2.1 Appropriate Usage The 485 data module enables you to setup cable-connected RS485 communication. The 485 data module can be retrofitted, or installed in the inverter at the factory if specified in the order. The inverter still complies with the standard after the product has been installed.
Damage to the 485 data module or the inverter due to electrostatic discharge Touching electronic components on the 485 data module or in the inverter can cause damage to or destroy the 485 data module and the inverter through electrostatic discharge.
Check the scope of delivery for completeness and any externally visible damage. Contact your specialist dealer if the delivery is incomplete or damaged. If the 485 data module has already been installed in the inverter at the factory, only those parts necessary for electrical connection are included in the scope of delivery.

(torque: 3.5 Nm ± 0.3 Nm). 3. Insert the module in the inverter. Position the plug at the bottom of the 485 data module in the socket and lead the spacers through the holes in the 485 data module.
5 Electrical Connection SMA Solar Technology AG 5.4 Preparing the Cables Disturbance of data transmission due to AC cables During operation, AC cables generate an electromagnetic field which may induce interference in plant communication. • Do not lay the cables of the RS485 communication together with the AC cable.
If you wish to connect one or two cables to the 485 data module and do not want to use the multi-function relay in the inverter neither immediately nor at a later time, prepare the M25 cable gland on the inverter for one or two cables.
