How to install SDR-480-24
- Power down the control panel and verify there is no supply voltage present before wiring the unit.
- Mount the SDR-480-24 on a standard DIN rail (TS-35) inside the enclosure, ensuring it sits securely and remains free of obstructions.
- Connect the input wiring to the L and N terminals on the power supply, observing correct polarity and tightening screws to a secure connection. Connect Protective Earth (PE) if provided or required by local code.
- Attach the output load to the 24 V DC (+V) and 0 V (-V) terminals, keeping wiring neat and within current ratings to avoid overheating.
- Power up the cabinet and verify the Power-on LED illuminates. Check the DC OK relay contact status and ensure it is signaling proper output health to your controller or alarm system.
- Test critical loads with a controlled inrush scenario to confirm peak-load tolerance and protective features respond as expected.
- Document the installation with panel photos and wiring diagrams for future maintenance, and ensure cable management keeps inputs and outputs segregated from high-noise sources.
- Regularly inspect terminal connections and enclosure ventilation to prevent heat buildup and maintain reliable operation in continuous-duty applications.
Frequently asked questions
