Connecting the TMAC Generation Signalling Device (GSD) to your inverter is crucial for optimal performance. Here's a step-by-step guide:
Mounting Location: The TMAC GSD should be installed inside the switchboard, close to the inverter.
Power Cable Connection: Connect the TMAC GSD's 'POWER CABLE' to the Main Switch Inverter Supply (MSIS) within the switchboard. Always adhere to local wiring regulations such as AS/NZS 3000.
Control Cable Connection: The 'CONTROL CABLE' from the TMAC GSD connects to the dedicated Demand Response Mode (DRM) terminals on your inverter. If the cable isn't long enough, use a Cat5e (or higher) extension cable. Splice the cables within the switchboard, ensuring the extension complies with AS/NZ4755.1 and maintains the correct RJ45 pin assignments.
Wiring Overview: The TMAC GSD uses two cables: a POWER cable for power and signal input, and a CONTROL CABLE to connect to the Inverter's DRM terminal.
Control Cable Wiring: Refer to the wiring diagram provided with the TMAC GSD for the correct way to connect the CONTROL CABLE to your inverter's DRM connection terminals. Ensure this connection is separate from any AC power cable connections.
Power Cable Wiring: The POWER CABLE provides power to the TMAC GSD. It should be connected to the Main Switch Inverter Supply (MSIS) within the switchboard.
Important Notes: Each inverter requires its own TMAC GSD. Do not attempt to adjust the internal components of the GSD, as they are factory-set. Following these steps and diagrams will help ensure the TMAC Generation Signalling Device works correctly with your inverter.
