When installing this equipment, follow the manufacturer’s installation drawing.
Installation should be in accordance with ANSI/ISA RP 12.06.01 “Installation of
Intrinsically Safe Systems for Hazardous (Classified) Locations” and the National
Electrical Code (ANSI/NFPA 70).
Associated apparatus connected to the barrier must not use or generate more than
250 Vrms or Vdc.
x
Resistance between Intrinsically Safe Ground and earth ground must be less than 1.0
Ohm.
x
In case of using cable glands in Outdoor location, they shall be UV rated or made of metal.
WARNING
- Substitution of components may impair Intrinsic Safety
- To prevent ignition of flammable or combustible atmospheres, disconnect power
before servicing or read, understand and adhere to the manufacturer’s live
maintenance procedures.
