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.
