Ensure the locking tabs are fully engaged. In high-vibration applications, we recommend additional DIN rail anchors on both sides of the combined assembly. Avoid installing the module in areas with direct sunlight or near high-heat sources, as excessive heat can degrade the 20 MHz oscillator's accuracy.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMemory Protection\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAs a legacy M1 adapter, ensure the internal battery or capacitor backup is checked during routine maintenance.
