This manual covers the electrical installation of the SEW MOVIRET DC converters, including connection circuit diagrams, set‑point terminal wiring, actual‑value terminals and external current‑limit configuration. Detailed diagrams and jumper settings are provided for each model in the 315/328/355/380/3150 series.
The service section describes mechanical arrangement, LED status indicators, a comprehensive troubleshooting table, fault causes with remedial measures, and full technical specifications such as mains voltage, frequency, rated currents and dynamic current limitation. The document is intended for technicians performing installation, maintenance and repair.
| Mains frequency | 50 Hz (changeable to 60 Hz) |
|---|---|
| Phase input at rated power output (315) | 12.5 A AC |
| Unit rated current Iₙ (315) | 15 A DC |
| Dynamic current limitation | 150 % Iₙ for 15 s |
LED ESB green on means the increased (dynamic) current limit is active, i.e., the unit is operating at 150 % of the rated current.
Check that mains voltage is present at terminals 1‑3, remove all fuses, inspect continuity of the fuses and wiring, and replace any defective fuses.
