Note
To connect the EDP300 Remote Sensor, a cable with the
following specifications needs to be used:
•
3-wire, cross-section 0.5 to 1.0 mm²
•
shielded, with at least 85 % coverage
•
Temperature range up to at least 100 °C (212 °F)
The cable glands must also be approved for a temperature range
up to at least 100 °C (212 °F). The cable glands require a
mounting for the shielding and strain relief for the cable in
addition.
ABB optionally offers a cable gland and cable for the EDP300
Remote Version.
