Description
The GUTOR 0M-94010 is a high-current PXW Diode Module used in GUTOR industrial UPS and power-conversion systems. GUTOR system parts lists identify this component specifically as a Diode Module PXW, with versions documented for current ratings up to 365 A or 600 A, depending on the system configuration.
The component is used in the power-conversion section of PXW equipment and is normally installed as part of a larger rectifier/UPS assembly. It is not a general-purpose low-voltage diode module.
The complete part number 0M-94010 should be checked against the original equipment BOM and the physical module before replacement.

⚙️ Operating Guidelines
🔹 Confirm the complete part number 0M-94010.
🔹 Check the current rating specified by the host GUTOR system.
🔹 Verify the original equipment BOM and reference position, commonly A015.
🔹 Inspect the diode module for cracks, overheating, discoloration, loose terminals, and damaged mounting surfaces.
🔹 Check the associated semiconductor fuses and DC bus connections before commissioning.
🔹 Confirm correct polarity and electrical orientation.
🔹 Use appropriate high-voltage and ESD safety procedures.
🔹 Never install or remove the module while the UPS power section is energized.
🛠️ How to Use
- 🔍 Verify the module number and host GUTOR system.
- ⚡ Shut down the UPS or PXW power-conversion system.
- 🔌 Isolate all AC and DC power sources.
- 🔒 Apply lockout/tagout.
- ⏳ Allow the DC bus and capacitors to discharge.
- 🧪 Verify absence of hazardous voltage.
- 🧤 Use suitable electrical protection.
- 🧩 Remove the existing diode module.
- 🔧 Install the 0M-94010 in the correct mounting position.
- 🔗 Reconnect the power connections with the correct polarity.
- 🔩 Tighten power connections according to the equipment service specification.
- 🔍 Inspect the associated semiconductor fuses and wiring.
- ⚡ Restore power following the GUTOR startup procedure.
- 📊 Monitor rectifier/DC-bus behavior.
- 🚨 Check for abnormal alarms or overheating.
- ✅ Perform a controlled load test.
🔌 Power-On Sequence
- 🔍 Inspect the diode module and power connections.
- 🧰 Confirm correct mechanical installation.
- 🔗 Verify diode polarity and terminal connections.
- 🛡️ Confirm associated semiconductor protection is correctly installed.
- ⚡ Restore the input supply according to the UPS procedure.
- ⏳ Allow the rectifier section to initialize.
- 📊 Monitor DC voltage and charging current.
- 🚨 Check for rectifier or protection alarms.
- 🌡️ Monitor the power section for abnormal heating.
- ✅ Return the UPS to normal operating mode.
⛔ Power-Off Sequence
- Notify the responsible operator.
- Place the UPS/load in a safe operating state.
- Shut down the GUTOR UPS normally.
- Isolate AC input power.
- Isolate battery/DC sources.
- Apply lockout/tagout.
- Wait for the specified DC-bus discharge period.
- Verify zero hazardous voltage.
- Remove the diode module only after complete isolation.
⚠️ A high-current UPS diode module can remain connected to dangerous DC energy even after the main AC supply has been switched off. Qualified electrical personnel should perform replacement.
📘 Product Usage Notes
The 0M-94010 is documented as a PXW diode module in several GUTOR equipment parts lists. One PEW 1060-220/220-EN BOM specifies IDC ≤600 A, while another GUTOR PEW configuration lists the same part number with IDC ≤365 A.
This difference is important when selecting a replacement. Do not use 600 A as a universal rating for every 0M-94010 installation. The correct operating limit must be determined from the host UPS/PXW system configuration.
The 0M-94010 is also listed alongside GUTOR rectifier modules, semiconductor fuses, DC chokes, and other power-conversion components, confirming its role within the high-power section of GUTOR UPS equipment.
❓ Common Questions & Answers
Q: What is GUTOR 0M-94010?
A: It is a high-current PXW diode module used in GUTOR industrial UPS and power-conversion equipment.
Q: What is the main function?
A: It provides high-current diode/rectification functionality within the PXW power section.
Q: What current rating does it have?
A: GUTOR documentation shows different system ratings, including IDC ≤365 A and IDC ≤600 A. The correct value depends on the host system.
Q: Is 0M-94010 a control PCB?
A: No. It is a high-current semiconductor power module.
Q: What is the series?
A: It is associated with the GUTOR PXW power-conversion series.
Q: Where is it installed?
A: GUTOR BOMs identify it at reference position A015 in the PXW power assembly.
Q: Can any diode module replace it?
A: No. Voltage rating, current rating, mechanical mounting, thermal characteristics, polarity, and electrical configuration must all match.
Q: Can the module be hot-swapped?
A: No hot-swap capability should be assumed. The UPS must be properly shut down and electrically isolated.
Q: Should the semiconductor fuse also be checked?
A: Yes. A failed diode module may be associated with a damaged semiconductor fuse or an underlying rectifier fault.
Q: What should I check before purchasing?
A: Check 0M-94010, host UPS model, PXW configuration, current rating, mounting arrangement, polarity, and the physical markings on the original module.
Q: Is 0M-94010 suitable for every GUTOR UPS?
