Allow for ambient temperatures up to 70 °C and avoid covering ventilation areas to maintain reliable operation.
Usage recommendations
The power supply should be installed by qualified personnel. For long-term reliability, avoid sustained operation at maximum rated temperature and provide periodic inspection for secure connections. Use appropriate surge protection if the installation is exposed to frequent high-voltage transients.
