This document is the operating instructions for RESISTRON LF-xx480 GB. It explains that RESISTRON and CIRUS control loops must be operated with interference suppression filters to comply with EMC directives and obtain the CE mark. ROPEX line filters are specially optimized for use in RESISTRON and CIRUS control loops, and when installed and wired correctly, they guarantee compliance with the EMC limit values.
This document provides operating instructions for the RESISTRON LF-xx480 series of line filters. These filters are specifically optimized for use with RESISTRON and CIRUS control loops to damp phase-angle control reactions on the line, protect controllers against system disturbances, and guarantee compliance with EMC limit values (EN 50081-1 and EN 50082-2) required for the CE mark.
The manual details technical specifications including maximum voltage of 480 VAC at 50/60Hz, continuous current ratings up to 35.0A, and various pulse load capabilities depending on duty cycle. It also outlines installation steps requiring grounding via a galvanized mounting plate and specifies wiring procedures such as keeping connecting cables short (max 1.0m) and avoiding parallel laying of input/output wires.
| Maximum voltage | 480 VAC, 50/60Hz |
|---|---|
| Continuous current (Ta = +40°C) | 6.0A / 35.0A |
| Maximum pulse load (Duty cycle = 60%) | 7.5A / 45.0A |
| Cable connections | 6.3 x 0.8mm flat connector |
To damp the reaction of the phase-angle control on the line and protect the controller against system disturbances.
