temperature_note	NOTE: markedly different from PowerTitan 2.0's -30 to 50 C. The '-HT' suffix denotes a high-temperature variant; the narrower cold limit is printed, not a transcription slip.

enclosure_ip	IP55
fire_suppression	—
fire_suppression_note	NOT printed in the fetched transcription of datasheet V3. Deliberately left UNKNOWN - the PowerTitan 2.0's NFPA package was NOT carried across, as it is a US-market package and this is an IEC-market unit.
