4. Setup
4.1 DIN Rail Mounting
- Ensure the DIN rail (35 mm) is securely mounted within the control cabinet.
- Align the WAGO 750-601 module with the DIN rail.
- Press the module firmly onto the DIN rail until it clicks into place, indicating a secure attachment.
4.2 Wiring Connections
- Power Input: Connect the 24 VDC power supply to the designated input terminals. Observe polarity (+/-).
- Load Output: Connect the protected circuit's input to the designated output terminals.
- Fuse Installation: Insert the appropriate fuse (e.g., T 0.3 A, 240 V as indicated on some variants) into the fuse holder slot. Ensure the fuse is correctly seated.
- Verify all connections are tight and secure to prevent loose contacts.
5. Operating Instructions
The WAGO 750-601 Fuse Holder operates passively by providing overcurrent protection to the connected circuit. Once installed and wired, it continuously monitors the current flow. If the current exceeds the fuse's rated value, the fuse will blow, interrupting the circuit and protecting downstream components.
- Normal Operation: With a healthy fuse and proper power supply, the module allows current to pass through to the protected circuit.
- Fuse Blown Indication: Some fuse types or external indicators may provide visual feedback when a fuse has blown. Always verify circuit continuity if a fault is suspected.
6. Maintenance
Regular maintenance ensures the longevity and reliable operation of the WAGO 750-601 Fuse Holder.
- Periodic Inspection: Visually inspect the module and its connections periodically for any signs of damage, corrosion, or loose wiring.
- Fuse Replacement: If a fuse blows, always disconnect power before replacing it. Replace with a fuse of the exact same type and rating as specified for the application.
- Cleaning: Keep the module clean and free from dust and debris. Use a dry, lint-free cloth for cleaning. Do not use abrasive cleaners or solvents.
- Environmental Check: Ensure the operating environment remains within the specified temperature and humidity ranges.
7. Troubleshooting
This section provides guidance for common issues encountered with the WAGO 750-601 Fuse Holder.
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to protected circuit | Blown fuse | Disconnect power, replace fuse with correct type and rating. Investigate cause of overcurrent. |
