There is no PDF catalog available on public databases, but the wiring is universal:
He saw the GMR32B being built in 1987. He saw the first shift lead, a man named Gerald, use this same procedure to fix a jam—only to vanish, leaving only his shadow burned into the concrete floor. He saw Rosa, twenty years younger, using it to save the plant from a meltdown, her left hand left behind, replaced by a prosthetic she never explained.

A GMR32B that feels hot is usually a symptom of an external condition – high ambient temperature, poor ventilation, loose connections, overcurrent from an overloaded motor, severe voltage imbalance, or improper installation downstream of a VFD. The unit’s internal design is robust (digital circuit, micro‑controller, operation from ‑25 °C to +55 °C), but it cannot “cool itself” if the surrounding environment exceeds its limits. : Verify the indicators; a Green PWR light
"The GMR32B must be mounted vertically with fins aligned for natural convection. Horizontal mounting reduces cooling capacity by 40% and voids warranty."
He flipped open the manual. Pages: calibration, waveform tuning, load balancing. Nothing worked. The fault light pulsed like a heartbeat.
Once you have resolved the immediate overheating issue, implement the following preventive measures: He saw Rosa, twenty years younger, using it
