! Warning For use Do not change the composition parts and circuits. Safety barrier must be in totally enclosed constraction-case and installed in non- hazardous area. For grounding Connect Safety Barrier to ground separately according to A class grounding. Connect Pressure Transmitter to ground according to D class grounding. Note: Actual construction of the details grounding, refer to a releavant the guideline for explosion-proof electric equipment in each country. For wiring To identify intrinsically safe circuits by color, use light blue cable or cable wrapped light blue tape around terminal of cable in wiring. Wires of intrinsically safe circuit must be used by rating or less. Use 600 V polyvinyl chloride insulated wire (JIS C07) or wire with characteristic of insulation equal to or better than insulated wire (JIS C07), or instrumentation cable (JISC6) that cross-sectional is 0.5 mm 2 or more. The external wiring of the intrinsically safe circuit must be separated from other circuits. Because it is prevented from electromagnetic induction, electrostatic induction and contacting with other circuits. Use magnetic shield, such as metallic sheath, and separate intrinsically safe circuit from non- intrinsically safe circuit, to prevent the wiring of the intrinsically safe circuit in a panel from electromagnetic induction and electrostatic induction. In wiring, do some treatment that combustible gas should not leak to non-hazardous area. Note: For the details of wiring, refer to a releavantest guideline for explosion-proof electric equipment in each country.
