9 Decommissioning the InverterSMA Solar Technology AG <br />Installation Manual SBxx-1SP-US-41-IA-xx-12 63 <br />9 Decommissioning the Inverter <br />To decommission the inverter completely upon completion of its service life, proceed as described <br />in this Section. <br />CAUTION <br />Risk of injury due to weight of product <br />Injuries may result if the product is lifted incorrectly or dropped while being transported or <br />mounted. <br />• Transport and lift the product carefully. Take the weight of the product into account. <br />• Wear suitable personal protective equipment for all work on the product. <br />Procedure: <br />1. DANGER <br />Danger to life due to high voltages <br />• Disconnect the inverter from all voltage sources (see Section 8, page 61). <br />2. Remove the DC conductors from the DC-in terminal block. To release the conductors from the <br />terminals, open the terminals with a flat-blade screwdriver (blade width: 3.5 mm (0.14 in)). <br />While doing so, only touch the terminal block on the black enclosure. <br />3. Screw out the screws from the DC-in terminal block using a flat-blade screwdriver (blade <br />width: 3.5 mm (0.14 in)) and pull the terminal block out of the slot. While doing so, only touch <br />the terminal block on the black enclosure. <br />4. Remove the AC conductor L1, L2 and, if necessary, N from the AC-out terminal block. To <br />release the conductors from the terminals, open the terminals with a flat-blade screwdriver <br />(blade width: 3.5 mm (0.14 in)). <br />5. Screw out the screws from the AC-out terminal block using a flat-blade screwdriver (blade <br />width: 3.5 mm (0.14 in)) and pull the terminal block out of the slot. <br />6. Remove all equipment grounding conductors from the equipment grounding terminals. To do <br />this, remove each screw (TX 25) and remove the equipment grounding conductor from the <br />inverter; screw each screw back in (TX 25). <br />7. Remove the ribbon cable connecting the communication assembly to the Power Unit and plug <br />the ribbon cable into the COM slot in the Power Unit. <br />8. Remove all connection cables from the communication assembly. Tip: To release the cables <br />from the plugs, open the conduit entries using a suitable tool. <br />9. Remove all conduits with conductors from the inverter. To do this, screw the sleeves out of the <br />enclosure openings from the inside. <br />10. Seal all enclosure openings with sealing plugs. <br />11. Unscrew the two screws on the right and left side of the Power Unit (TX25) and retain them for <br />later use. As a result, the Power Unit and the Connection Unit are not connected to one <br />another. <br />12. Disconnect and remove the Power Unit from the Connection Unit. <br />EN <br />G <br />L <br />I <br />S <br />H <br />534 S Sycamore St <br />- 10110979707/01/22
