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).
Control equipment connected to the barrier/power supply must not use or generate more than 250
Vrms or Vdc.
・
Resistance between Intrinsically Safe Ground and earth ground must be less than 1.0 Ohm.
・
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.
