3.3 ETL Listed to ANSI/ISA-12.2.01-2011 Standards

The current output unit may be installed in Class 1 Hazardous (Classified) Group A, B, C, D Division

2 locations, if the unit was ordered N1 designation in the Part Number, 12

and 13

digits. Safety

barriers are not required as long as the unit is operated under normal conditions with a maximum

excitation voltage of 30 VDC between the input terminals.

C. Safety barriers are not required as long as the unit is

operated under normal conditions with a maximum excitation voltage of 30 VDC between the in-

put terminals. The following requirements must be met to maintain compliance to listed standards.

• WARNING - DO NOT SEPARATE WHEN ENERGIZED

• WARNING - DO NOT OPEN, MAINTAIN OR SERVICE IN AN AREA WHERE EXPLOSIVE ATMOSPHERE MAY

BE PRESENT

• A minimum degree of protection IP54 shall be maintained in the hazardous location. The zero/span plugs

shall be installed securely at all times when the transducer is in service. The mating connector provided by

the end user shall be in accordance with all applicable classes of EN60079-0 and EN60079-15.

• Connectors must be securely attached before power is applied

• The shielded cable must be used and the drain wire of the cable must be connected to the earth ground.

The transducer body must be connected to earth ground.

• The maximum allowable transient disturbance must not exceed more than 40% of the maximum

excitation voltage.

• No adjustment on Zero or Span potentiometer shall be made int he presence, or potential for, hazardous

atmosphere.

All Setra pressure transducers are carefully calibrated to the specific input pressure range vs. output voltage

or current at the factory so little or no field calibrating is necessary. Zero and span adjustments can be made

by turning the rotatable cover or disengaging the plugs to expose the zero and span pots. We recommend

covering the adjustments pots after calibration is complete.
