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 A
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
B
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.
