2. The load cells do not have an earth ground terminal or conductor. The load cells shall be earth
grounded as part of the final installation.
3. The non-metallic surfaces on the Load Cell's enclosure may cause risk from electrostatic
discharge. Avoid installation that could cause electrostatic build-up, and only clean with a
damp cloth.
Note
The resistance between all safety ground connections and the system grounding electrode shall
not exceed 1 ohm.
Note
The associated apparatus shall be a single entity-Approved/Certified associated apparatus device
with outputs that are Approved/Certified for parallel connection of field wiring within the
applicable hazardouslocation / explosive atmosphere Within the United States,the voltage and
current parameters of such associated apparatus are commonly identified using the parameters
Vt (voltage, total) and It (current, total) The use of multiple associated apparatus that are not
Approved/Certified for use in combination with one another as a system is only permitted as
specified below.
