In these three operation modes the ECG does not switch off as soon as Vset exceeds 11V (no protection region).

Wrong wiring This control gear is inherently protected against wrong wiring. The wrong connections between LED+ with Vset and GNDset could damage irreversibly the ECG. All the other wrong wirings on the secondary side, once removed, make the ECG work regularly. LED- and GNDset terminals cannot be connected together. Installation notes The luminaire manufacturer is responsible for providing the required clearances and creepage distances and also for the protection against electrical shock, especially for the line and load wires according EN 60598.
