4. O'rnatish va o'rnatish
The Grothe 14101 transformer is designed for rail mounting (DIN rail). Follow these steps for safe and correct installation:
- Quvvatni uzish: Ensure the main power supply to the installation area is completely disconnected at the circuit breaker.
- O'rnatish: Securely mount the transformer onto a standard DIN rail within an appropriate electrical enclosure.
- Primary Wiring (Input):
- Connect the 230V AC (Live) wire to terminal 5.
- Connect the 230V AC (Neutral) wire to terminal 8.
- Refer to the wiring diagram on the transformer label (Figure 3.1) for visual guidance.
- Secondary Wiring (Output):
- Connect one wire of your 12V AC doorbell system or load to terminal 1.
- Connect the other wire of your 12V AC doorbell system or load to terminal 3.
- Ensure the total current draw of the connected devices does not exceed 1.5 A.
- Ulanishlarni tekshirish: Double-check all wiring connections for tightness and correctness to prevent short circuits or loose contacts.
- Quvvatni tiklash: Once all connections are verified and the enclosure is closed, restore power to the circuit.
Note: The transformer includes a PTC thermistor for protection against short circuits and overloads on the secondary side. In case of an overload, the PTC will limit the current, and the output voltage may drop. It will automatically reset once the overload condition is removed and the device cools down.
