SMA Solar Technology AG Safety 1.3 Terminology The RS485 communication module (DM-485CB-10) is referred to as "module" in the following chapters. 2 Safety 2.
Unpacking SMA Solar Technology AG 3 Unpacking 3.1 Packing List Marker A B Number 1 2 Designation Module (485I-MOD-G1.BGCB) Conductive adhesive foil C 2 The adhesive foils are stuck to the shield clamps of the module upon delivery. Connector D E 1 1 In a plug a resistor is plugged for termination. M32 cable gland Installation guide with RS485 cabling plan poster 3.2 Check for Transport Damage Also check the module for visible external damage. Please contact your dealer if you find any damage. 3.
SMA Solar Technology AG Electrical Connection 4 Electrical Connection 4.1 Notes In this guide it is assumed that the inverter is situated in the middle of the RS485 bus. If the inverter is situated at the end of the RS485 bus, carry out the following steps for one cable only and connect the termination (see Section 4.6 ). The illustrations for the inverter of type STP 1x000TL-10 can slightly deviate in this manual. 4.
Electrical Connection SMA Solar Technology AG 4.4 Installing the module in the inverter 1. Open the inverter as described in the inverter manual. 2. Loosen the screw of the display, until the display can be flipped up. Flip up the display until it clicks into place. Preparing the cable opening on the inverter 3. Press the filter plug out of the second cable opening on the left side. 4. Unscrew counter nut from the delivered cable gland.
SMA Solar Technology AG Electrical Connection 5. Place the cable gland into the enclosure opening of the inverter and fastening it along with the counter nut from inside. ☑ The cable opening on the inverter is prepared. Inserting the module 6. Place the module as shown in the illustration and push the ribbon cable behind the display upwards. The guide lug at the rear edge of the module must fit into the hole in the plastic mount in the inverter. 7. Secure the module with the screw.
Electrical Connection SMA Solar Technology AG 8. Flip down the display. 9. Place the ribbon cable on the connector strip. ☑ The module is installed.
SMA Solar Technology AG Electrical Connection 4.5 Connecting the module to the RS485 bus 1. Open the inverter as described in the inverter manual. 2. Loosen the screw of the display, until the display can be flipped up. Flip up the display until it clicks into place. Preparing the cable NOTICE! Metal or cable scraps in the enclosure can damage the inverter. • Carry out the following steps outside the inverter to prevent any metal scraps from the shield or cable from falling into the open inverter. 3.
Electrical Connection SMA Solar Technology AG 7. Cover the shield with the delivered conductive adhesive foil. 8. Unscrew the nut of the cable gland from the inverter. 9. Press the seal out of the cable gland from the inside. 10. Remove 1 or 2 filler plugs from the cable gland. If only one cable (inverter at the end of the RS485 bus) is used, leave the second filler plug in place. 11. Plug 1 or 2 cables into the nut and the seal. ☑ The cable is prepared.
SMA Solar Technology AG Electrical Connection Connecting cable to the module 12. If two cables are connected (inverter in the middle of the RS485 bus), remove the resistor of the the termination plug. If one cable is connected (inverter at the end of the RS485 bus) leave the resistor connected. If the resistance is not correctly connected, see chapter 4.6 . 13. Insert the end of the cable through the cable gland in the inverter. 14. Loosely screw the nut of the cable gland. 15.
Electrical Connection SMA Solar Technology AG 19. Flip down the display and secure it with the display screw. 20. Close the inverter as described in the inverter manual. 21. Connect the other end of the cable to the RS485 bus. See the RS485 cabling plan poster for the connection layout and system wiring. 22. Lay the cable using suitable fastening material. Do not lay the cable of the communication parallel to the AC cable.
SMA Solar Technology AG Electrical Connection 4.6 Terminating the RS485 Bus You must set the termination only on the inverter that is located at the end of the RS485 bus. Upon delivery of the module, the resistance of the termination connector is connected to the plug connection on the right. Termination of the RS485 bus. Refer to the RS485 cabling plan poster for the termination of an RS485 bus. Proceed as follows: 1. Open the inverter as described in the inverter manual. 2.
Decommissioning SMA Solar Technology AG 5 Decommissioning 1. Open the inverter as described in the inverter manual. 2. Remove the plug for the ribbon cable of the module as shown in the figure. 3. Loosen the screw of the display, until the display can be flipped up. Flip up the display until it clicks into place. 4. Open spring-type terminals of the connector on the module and remove all insulated conductors. 5. Unscrew the nut of the cable gland. 6. Remove the cable from the shield clamp. 7.
SMA Solar Technology AG Troubleshooting 6 Troubleshooting Problem Cause Emergency channel list The module is installed in an "Emergncy" or "EmgncyXX" inverter of type SB x000TL-20 without first disconnecting the After the installation of the module, the emergency channel inverter on the AC and DC sides. Rectification Before installation of the module, disconnect the inverter on the AC and DC sides, as described in the inverter manual.
