Referring to the appropriate size of XFE, mount the XFE ensuring that correct clearances are maintained
for adequate ventilation and operation of the XFE.
2 Wiring Diagrams
Referring to the appropriate Wiring Diagram, install the XFE electrical connections ensuring that the correct
control supply voltage is used and is within its specified operating limits as described on the product
specification
ACCESS
Caution: Always replace the cover panel on the unit after gaining access
to the electrical connections.
The unit requires two AC supplies:
A 3 phase balanced Mains Supply to provide the source of power for the controlled motor.
A single phase supply: 115V/230V, 50Hz/60Hz, for the internal control circuitry.
XFE 300 series need a separate 115V or 230V supply to power the fans.
Voltage must be specified prior to supply of the XFE.
IMPORTANT Ensure that the voltage selector switch position corresponds to
the control supply before you apply the control supply voltage.

ISOLATION
Caution: The XFE uses semiconductor devices in the main circuit and is not designed to provide
isolation. For this reason isolation means must be installed in the supply circuit in accordance with
the appropriate wiring and safety regulations.
The Mains Supply and the Control Supply each require protection. Although all units have electronic
overload protection, the installer should always place fuse protection between the unit and the Mains
Supply, not between the unit and the motor. Semiconductor fuses can be supplied for short circuit
protection of the semiconductors.
3 Keypad operation and basic set-up
Refer to this, for familiarisation with the keypad controls of the XFE. Use the illustration of the Basic Menu
structure to find XFE menu items on the display.
4 Set-up examples
Set-up basic XFE operating parameters, if necessary, by following one or all of the examples described
here.
5 Product information
Refer to product information for details of Design Standards and Approvals, operating and storage limits
and other installation instructions.
Further Information
Further information about the XFE soft start motor controller, detailed manuals and application notes are
available on the Fairford website or from Fairford direct (see back page for contact details).
