Lay shielded cable,
with shield connected to ground at both ends
Terminal 54 (sense) is used for compensating
cable resistances; for this, the cable from terminal 53 to the
temperature sensor and the cable from connection 54 to the
temperature sensor should be around the same length.
If terminal 54 (sense) is not required, then
terminal 54 must be connected to terminal 55.
