Operation above 25 C is limited to how many minutes?

• A. 5 minutes
• B. 2 minutes
• C. 1 minute
• D. 10 minutes

Answer: (B)

When equipment runs in hotter conditions, its ability to shed heat becomes the limiting factor. If the ambient temperature is above 25 C, the operation is limited to a brief duration to keep temperatures within safe levels. Two minutes is the designated maximum, reflecting the balance between how quickly heat builds up and how effectively the system can cool, so that performance isn’t compromised or protection mechanisms aren’t triggered. Going beyond that window increases the risk of overheating, which can lead to degraded performance or automatic shutdown. If more operation is needed, you’d pause to cool or reduce the load, or wait for cooler conditions.
