DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
b Only qualified electrical workers should install this equipment. Such work
should be performed only after reading this entire set of instructions.
b NEVER work alone.
b Isolate the temperature sensors from dangerous voltages.
Failure to follow these instructions will result in death or serious injury.
DE51649
Connecting the Ground Terminal
Use a tinned copper braid with a cross-section ≥ 6 mm² (AWG 10) or cable with a
cross-section ≥ 2.5 mm² (AWG 12) and length ≤ 200 mm (7.9 in), fitted with a
4 mm (0.16 in) ring lug.
Check the tightness. The maximum tightening torque is 19.5 in-lb (2.2 Nm).
Connection of RTDs to Screw-Type Connectors
b One wire with cross-section 0.2 to 2.5 mm² (AWG 24-12); or
b Two wires with cross-section 0.2 to 1 mm² (AWG 24-18)
The recommended cross-sections according to distance:
b Up to 100 m (330 ft) ≥ 1 mm² (AWG 18)
b Up to 300 m (990 ft) ≥ 1.5 mm² (AWG 16)
b Up to 1 km (0.62 mi) ≥ 2.5 mm² (AWG 12)
Maximum distance between sensor and module: 1 km (0.62 mi)
Wiring Precautions
b Use shielded cables whenever possible.
Unshielded cables can cause measurement errors that vary in degree
according to the level of surrounding electromagnetic disturbance
b Connect the shielding only at the MET1482 end, in the shortest manner
possible to the corresponding terminals of connectors and
b Do not connect the shielding at the RTD end.
Accuracy Derating According to Wiring
The error Δt is proportional to the length of the cable and inversely proportional to the
cable cross-section:
b ±2.1°C/km for 0.93 mm² cross-section (AWG 18)
b ±1°C/km for 1.92 mm² cross-section (AWG 14).
