Use these checks to narrow the results and find instructions that apply to your product.

  1. Record the complete variant

    Copy the model, suffix, and phase or rating details from the product label. Closely named protection devices can have different terminals and menus.

  2. Match the terminal diagram

    Compare the diagram identifier and device version in the manual. Use the manufacturer’s installation requirements and specified qualification level for electrical work.

  3. Look up parameter definitions

    Find the exact menu label in the parameter table. Use the documented range, units, and application requirements rather than settings copied from another model.

  4. Find display and support information

    Search the model with the exact display message or parameter name. Use the matching troubleshooting and manufacturer support route when the document does not resolve the issue.

Common questions

How to save or print a manual →
Can I use settings from a similar voltage protector?

Use the parameter definitions and requirements for the exact device and application. A similar model number does not establish the same ratings, menu, or protection settings.

Where is the terminal diagram?

Look for installation, wiring, terminals, or connection diagram in the matching manual. Confirm the complete phase and rating variant.

Does this page provide electrical installation instructions?

This page locates documentation. Follow the manufacturer’s requirements for installation and qualified electrical work in the matching document.

How do I search for a TOMZN manual?
