Electrical connection
Connect the positioner (EDP300 Control Unit, housing 1) and
remote position sensor (EDP300 Remote Sensor, housing 2),
while following the instructions below:
• The EDP300 Remote Sensor and the EDP300 Control Unit
are adjusted to each other. Ensure that only devices with
the same serial number are connected.
• A shielded 3-wire cable with a maximum length of 10 m
(33 ft) must be used for the connection.
• Route the cable into the terminal compartment through
the EMC cable glands. Ensure that the shielding is
secured correctly in the EMC cable glands.
• Connect the cables in accordance with the electrical
connections and tighten the screws of the terminals so
that they are hand-tight.
• Use wire end ferrules when connecting.
• The electrical connections of the EDP300 Control Unit
and the optional modules are carried out as described in
Connection on the device on page 35.
• If the EDP300 Control Unit is fastened so that it is it non-
conductive, the housing must be grounded
(EDP300 Control Unit and EDP300 Remote Sensor
housing with the same electric potential); otherwise
control deviations could occur with regard to analog
position feedback.
• In the EDP300 Remote Sensor in IP rating IP 66, pre-
tighten the cover screws by applying approx. 50 Ncm
(0.44 lbf-in) cross-wise and then tighten by applying
200 Ncm (1.77 lbf-in).
• The pneumatic outputs to the actuator must be
connected using pneumatic lines with a minimum
diameter of 6 mm.
