GROUNDING NOTES
CABLE NOTES
INTRINSICALLY SAFE TERMINAL NOTES
1. The resistance between the ground screw and the system
earth ground must be < 1 Ohm.
2. The transducer ground wire shall be connected to drain wire
or shield wire of cabling. Do not terminate drain wire at panel.
1. Probe terminals may only be connected to U.L. listed 950xxxB
model probes (xxx = probe length).
2. Contact terminals may only be connected to passive contacts.
3. Wiring shield cover must be installed securely in place prior to
applying operating power.
1. Cable sets that run together must be installed per ISA
Standard #RP126.
2. For transducer cable lengths up to 1000 ft., shielded cable
(#8441 Belden or equivalent) or heavier gauge can be used,
cable capacitance shall be < 60 pF per foot. Cable
inductance shall be < 0.2 H per foot.
m
3. For contact cable lengths up to 1000 ft., unshielded twisted
pair cables are recommended. Cable capacitance shall be
< 60 pF per foot. Cable inductance shall be < 0.2 H per foot.
4. For transducer and/or contact cable lengths exceeding 1000 ft.
and up to 2500 ft., twin axial Belden cable #9182 (U.L. 2606)
must be used.
