Wiring inforMAtion
The length of RTD extension wires is determined by the wire
gauge used.
To reduce the likelihood that electrical noise will affect
temperature measurement, keep RTD extension wires as short as
possible.
Use shielded instrument cable such as Raychem MONI-RTD-WIRE
(22AWG, PVC insulation, –30°F to 140°F, –20°C to 60°C) or Belden
83553 (22 AWG, FEP insulation, –95°F to 395°F, –70°C to 200°C).

electrical Wiring notes:
Most electrical codes (such as NEC 725–15) permit Class 1 circuits
to occupy the same cable, enclosure, or raceway without regard
to whether the individual circuits are alternating current or direct
current, providing all conductors are insulated for the maximum
voltage of any conductors in the cable, enclosure or r aceway.
Additional Materials required
• Approved junction box (supplied by others)
• HAK-C-100
• Pipe strap
rtD7Al Wiring
Connect the wires as shown.
1 note: Ground RTD extension wire shield at one
end only, preferably at Raychem electronics end.
2 note: RTD housing must be properly grounded
using the screw provided.
