This article serves as a . While the official GMR32B documentation covers installation and basic specs, it rarely dives deep into the symptoms of thermal failure . Below, we dissect why these units overheat, how to diagnose the issue using your manual’s schematics, and the step-by-step process to cool down your system safely.

Connect the output relay terminals () in series with the electromagnetic coil of your primary motor contactor or Variable Frequency Drive (VFD) control loop.
