Note
If the device is being operated on a cylinder, for reasons
associated with linearity you should run the Auto Adjust function
for rotary actuators (see chapter Start automatic adjustment on
page 43).

A
EDP300 control unit with EDP300 remote sensor
In this version, the components are supplied in two housings,
which together form one harmonized unit.
The following points should be observed during installation:
• Housing 1 (EDP300 Control Unit) contains the electronics
and pneumatics and is mounted separately from the
actuator.
• Housing 2 (EDP300 Remote Sensor) contains the position
sensor and is mounted on the linear and rotary actuator.
Mechanical mounting is described in chapter Mechanical
mounting on page 17.
• Electrical connection is carried out as described in
chapter EDP300 Remote Sensor Electrical Connection on
page 25.
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.

EDP300 Control Unit for remote position sensor
In this version the positioner is supplied without a position
sensor.
The following points should be observed during installation:
• Housing 1 (EDP300 Control Unit) contains the electronics
and pneumatics and is mounted separately from the
actuator.
• The remote position sensor is mounted on the linear
actuator or rotary actuator. Follow the operating
instructions for the remote position sensor for
mechanical mounting!
• Electrical connection is carried out as described in
chapter Connection to device - EDP300 Control Unit for
remote position sensor on page 32.
