• Construction: 16GA (0.060"/0.1524cm) powder coated steel
• Console Power Wiring Requirements: AC Power Wiring – Wires carrying 120 or 240VAC from power panel to the console should be #14 AWG (or larger) wire for line, neutral & chassis ground (3); and 4 sq. mm, rated for at least 90C for barrier ground.
• Probe & Sensor to Console Wiring Requirements: 1. Wire Type – Shielded cable required regardless of conduit materiel or application. Shielded cable must be rated less than 100 picofarad per ft manufactured with a suitable material such as Carol C2534 or Belden 88760, 8760, or 8770. Cable must be oil and gas resistant. 2. Wire Length – maximum 1,000ft (304.8m) to meet intrinsic safety requirements. Improper system operation could result for runs over 1,000ft (304.8m). 3. Wire Gauges – Color coded – shielded cable used in all installations. Wires should be #14 - #18 AWG stranded copper wire and installed as Class 2 circuits. As an alternate method when approved by the local authority having jurisdiction, #22 AWG wire such as 88761 may be suitable with the following requirements: wire run is less than 750ft (228.6m), Capacitance does not exceed 100 pF/foot, Inductance does not exceed 0.2 uH/ft.
