Frequently asked questions

What safety warnings are included in the manual?

The manual uses warning triangles for personal safety hazards and provides a hierarchy of warnings (danger, warning, caution, notice) to prevent injury or property damage.

What types of loads can be connected to the module?

Both capacitive and inductive loads can be connected, but the manual advises using external suppression circuits for inductive loads and limiting capacitive load size to avoid short‑circuit or overload detection.
