Part 4: Appendices
Reduced voltage operation
If the local voltage is below that specified on page 6, and there is a high
pumphead loading, provision has been made in the design of the drive for a
simple modification to be carried out. This will make the drive suitable for use
with voltages as low as 180 volts when the 220-240V setting is selected, and as
low as 90V when the 100-120V setting is selected.
Please note that the work should be carried out only by qualified personnel and
that there are components at mains voltage inside the drive. If the drive is found
to be damaged after this modification is incorporated and the damage is
considered to have been caused by connecting it to a "normal " voltage, the
warranty will be considered to have been voided.
The modification requires the connector J18 on the control PCB to be reversed.
To locate the terminal, isolate the mains supply then remove the pump cover
which is secured by 4 screws located on the underside of the pump. Lift the
cover to one side
