1 Mechanical Outlines
Referring to the appropriate size of QFE, mount the QFE ensuring that correct clearances are maintained
for adequate ventilation and operation of the QFE.
2 Wiring Diagrams
Referring to the appropriate Wiring Diagram , install the QFE electrical connections ensuring that the
correct control supply voltage is used and is within its specified operating limits as described on the prod-
uct specification

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.
IMPORTANT Ensure that the voltage selector switch position corresponds to
the control supply before you apply the control supply voltage.
ISOLATION
Caution: The QFE 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 pro-
tection of the semiconductors.
3 Keypad operation and basic set-up
Refer to this, for familiarisation with the keypad controls of the QFE. Use the illustration of the Basic Menu
structure to find QFE menu items on the display.
4 Set-up examples
Set-up basic QFE operating parameters, if necessary, by following one or all of the examples described
here.
5 Product information
