2. Bring the field wiring into the terminal box. When applicable, install conduit using local and national electrical codes
which apply to the application.
3. The instrument is not polarity sensitive. Connect one wire from the H1 card output to one of the LOOP screw
terminals on the pwb/terminal strip assembly in the terminal box shown in figure 2‐24. Connect the other wire from
the H1 card output to the other LOOP screw terminal in the terminal box.
WARNING
Personal injury or property damage can result from the discharge of static electricity. Connect a 14 AWG (2.08 mm
ground strap between the digital valve controller and earth ground when flammable or hazardous gases are present. Refer
to national and local codes and standards for grounding requirements.
4. As shown in figure 2‐24, two ground terminals are available for connecting a safety ground, earth ground, or drain
wire. The safety ground terminal is electrically identical to the earth ground. Make connections to these terminals
following national and local codes and plant standards.
WARNING
To avoid static discharge from the plastic cover when flammable gases or dust are present, do not rub or clean the cover
with solvents. To do so could result in a spark that may cause the flammable gases or dust to explode, resulting in personal
injury or property damage. Clean with a mild detergent and water only.
