3. Push the levers of the terminals 2, 5 and 7 of a terminal block upwards. 4. Connect the insulated conductors to the terminals 2, 5 and 7 and note the insulated conductor colors (see Installation Instructions "RS485 Cabling Plan" at www.SMA-Solar.com). 5. Close the levers of the terminals.
7 Decommissioning SMA Solar Technology AG Decommissioning Removing the Module Procedure: Danger to life due to high voltages of the PV array When exposed to sunlight, the PV array generates dangerous DC voltage, which is present in the DC conductors and the live components of the inverter. Touching the DC conductors or the live components can lead to lethal electric shocks.
SMA Solar Technology AG 7 Decommissioning • Slightly press the second locking tab outwards using the other hand and pull the module slightly forwards on the lower end until the module is released from the interlock of the locking tab.
