Before replacing NAM1.3-15, match the complete nameplate and machine configuration.
- Complete supply code: Verify the family, design, power rating, voltage class, cooling field, material number and all suffixes on the nameplate.
- Cabinet configuration: Identify incoming mains, transformer and line components, connected drive modules, total axis load and DC-bus arrangement.
- Braking and cooling: Record bleeder, regeneration, braking resistor, fan or cooling hardware and the machine duty that loads the supply.
- Fault evidence: Include fault indicators, fuse or breaker history, operating state and clear connection photos before the module is removed.
For repair, send the fault or symptoms. Helpful photos show the tag, complete unit, mounting and connections.
