Voltage selection and fuses
Precautions
Please ensure that the unit is set for the correct voltage for your local supply BEFORE use.
Operating voltage is indicated in the window of the main socket at the rear of the unit.
Power connection
Connection is made by means of an IEC standard power socket. The unit will operate with AC
main voltage between 90Vac and 125Vac 50-60Hz in 115v mode and 180Vac to 264Vac 50-60Hz
in 230v mode.
Please note that each mode requires a different fuse. Before
connecting to the main AC supply, ensure that the fuse fitted is the
correct type (time-lag T, slow blow) and rating (115V/T400mA or
230V/T200mA), as indicated on the rear panel, adjacent to the fuse
holder.
115/230 Switching
Voltage Selection Change requires no special tooling and can be performed in the field by
qualified service people.
DISCONNECT MAINS POWER TO THE UNIT, then follow these instructions:
• Open the fuse holder window in the power entry module located on the rear of the unit.
(External access)
• Remove the red fuse holder and insert the
corresponding fuse (115V/T400mA -
230V/T200mA) for the voltage required into the
opposite side of the holder.
• For safety reasons, when the fuse holder is
flipped around for voltage changing, the
conversion clip (small metal contact) should be
re-installed to the other side of the fuse holder.
Otherwise the fuse holder will not go back into the
housing completely and the power entry module
will not function.
The proper location of the conversion clip can be
checked in the following way. It should be located
to the left-hand side of the voltage number
selected, i.e., with the voltage label upright. See
diagrams opposite.
• Re-insert the red fuse holder, the required voltage
figure can now be seen in the fuseholder window.
• The unit is now ready for use.
APPLY FORCE ONLY TO THE SHOULDERS, NOT
TO THE CONTACT FINGER IN THE MIDDLE.
