Read Instruction manual QJ3749.*-E before beginning wiring work or using the system.2. Make sure that the capacitance of wiring outside the intrinsic safety circuit does not exceed 0.05 ?F,and that its inductance does not exceed 0.5 mH.3. The twisted pairs should use 1 and 2 as one pair, and 3 and 4 as the other.4. Refer to the "Recommended practices for explosion-protected electrical installations " or the "Users' guidelines forelectrical installations for explosive gas atmospheres in general industry" for further details for wiring work.5. Intrinsic safety construction Ex ia IIA T4.We offer intrinsically safe anti-explosion systems that canbe used safely in places where the atmosphere containsexplosive gases. The sensors are installed in the hazardousarea, and the controller is installed elsewhere (in a safelocation) with the two sides separated by a Zener barrier.Intrinsically safe anti-explosion systemsZener barrier boxIntrinsic safety Ultrasonic Sensor UH01S / SA field wiringSystem components
