Preparation of mechanical connection
Check the following items prior to replacing an existing RTD temperature converter.
• Number of elements
• Presence/absence of additional tank bottom and vapor phase spot temperature elements
other than average temperature elements
• Lowest element position
• Element interval
• Cable color for each element
Before installing NMT81, bundle all RTD cables from a temperature probe temporarily
using a zip tie or a short string so that the cables do not become damaged during the
mechanical connection process.

Cable handling procedure
1. Cut the ends of the cables so that they are the same length for connecting to NMT81.
2. Temporarily tie all the cables together to protect them against damages during the
mechanical connection process.
3. Maintain at least 250 mm (9.84 in) between the edge of the G3/4 screw connector
and the cable ends.
This completes the cable handling procedure.
