When a fault occurs, the GMR-32B cuts power output and flashes an alphanumeric error code.
The GMR-32B typically requires forced air. The internal fan should exhaust upward. In high-ambient temperatures (above 40°C / 104°F), derate the current by 15% per additional 10°C. gmr-32b phase controller manual
Proper wiring is critical to prevent ground loops, signal interference, and catastrophic hardware failure. Always isolate high-voltage lines from low-voltage control signals. Low-Voltage Control Terminals (Signal Input) When a fault occurs, the GMR-32B cuts power
There are two ways to physically mount the device: In high-ambient temperatures (above 40°C / 104°F), derate
The name of your GMR-32B controller (e.g., Carlo Gavazzi, Gefran, or a specific local brand).
The status LED indicators provide instant feedback on your three-phase line health:
: Connect input phases to U, V, and W. Run the control loop through the NO/COM relay output.
