2. Інфармацыя па бяспецы
Adherence to safety standards is crucial for the proper functioning and longevity of the device, as well as for user safety. This controller complies with relevant European standards.
- Злучальныя кабелі: Ensure connection cables guarantee insulation up to 90°C.
- 12 Vac Versions: For 12 Vac versions, use Class II transformers. To comply with immunity standards, the transformer must be a specified CAREL model. Double insulation cannot be guaranteed between power supply and relay outputs for 12 Vac/dc versions; use only safety low voltage loads (up to 42 V effective rated value).
- Даступны памер для ўстаноўкі: Maintain a space of at least 10 mm between the case and nearby conductive parts.
- Digital and Analog Input Connections: For connections less than 30 m away, adopt suitable measures for separating cables to ensure compliance with immunity standards.
- Output Cable Security: Secure the connection cables of the outputs to avoid contact with very low voltagе часткі.
