Important Technical Notes

1. Proper Selection:​ Choose the specific PRO MAX terminal block type based on application requirements: current rating, voltage, wire size, and function (fuse, disconnect, etc.).

2. Wire Preparation:​ Strip wire to recommended length (typically 10-12 mm). Use ferrules for stranded wires, especially for spring clamp connections.

3. Torque Values:​ For screw clamp versions, follow specified torque values to ensure reliable connections without damaging terminals.

4. DIN Rail Selection:​ Ensure compatibility with your DIN rail type (35mm, 32mm, or 15mm). PRO MAX supports standard DIN rails.

5. Separation:​ Use end plates and partitions to maintain proper creepage and clearance distances, especially for higher voltage applications.

6. Marking:​ Utilize the integrated marking system for clear circuit identification and easier maintenance.

7. Environmental Conditions:​ While rated for -40°C to +120°C, consider ambient temperature and heat from adjacent components when selecting current ratings.

8. Certifications:​ Verify that the specific PRO MAX product carries the necessary certifications for your market and application.
