Ensures the motors run in the correct direction (A-B-C rotation).
: Route the raw incoming three-phase lines directly to the sampling inputs of the GMR-32B. Ensure tight terminal seating to eliminate resistance spikes.

The GMR32B is maintenance-free except for:
⚠️ : Never install the GMR-32B sampling lines downstream on the output side of a Variable Frequency Drive (VFD) or inverter. Harmonics generated by VFD pulse-width modulation will degrade internal monitoring components. Step-by-Step Wiring Sequence Ensures the motors run in the correct direction
The manual is often cited for being straightforward, allowing for installation in just a few minutes.
Clear the panel of tools, close the enclosure door, and remove LOTO locks. Turn on the main circuit breaker. Terminal R (L1) →right arrow Phase A Power
Nuisance tripping usually stems from voltage instability or dirty contacts, while a failure to trip suggests improper wiring. Some models offer automatic power restoration once the phase sequence is corrected. AliExpress
