The machines are delivered for connection
to a 400V supply, but to be certain, check the
label on the end of the power supply cable,
or remove the cover and visually inspect the
Voltage changeover block. (see fig. 4).

If the supply voltage is changed, a
corresponding change must be made to the
terminal connectors on the ‘Voltage
Changeover’ block, located behind the right
hand side panel, as follows:

1.

Ensure the machine is switched OFF, and
completely disconnected from the
electrical supply, or if hard wired, the
fuse should be removed from the circuit.

2.

Remove the right hand side panel by
unscrewing the 6 securing screws.

3.

Change the connections of the ‘Voltage
Changeover’ block, as shown on the
label inside the unit, which is duplicated
above at fig 4.
