2. معلومات السلامة
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.
- كابلات التوصيل: 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).
- تخليص التثبيت: 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 voltagالأجزاء الإلكترونية.
