● The aluminum electrolytic capacitors in the power supply module (LQV410) have a limited lifespan.
We recommend that you replace the power supply module within 10 years.
The service life of the aluminum electrolytic capacitors is approximately 10 years at an ambient
temperature of 35°C. The service life halves with every 10°C increase in ambient temperature.
When keeping a spare power supply module in long-term storage, store it in an environment with a
temperature from 15°C to 40°C and humidity of 65% or less.
