Page 4 of the manual available online 
has detailed instructions for "OPERATION 
FROM AC VOLTAGE OF 230 VAC".
~~~~~~~~~~~~~~~~~~~
These units have been preset to operate 
from an input voltage of 120 VAC, 60
Hz. The units can be set to operate from 
an input voltage of 230 VAC, 60 Hz. by
changing the position of an internal 
jumper. The procedure for conversion to
input voltage of 230 VAC, 50 Hz. is as 
follows:
. Switch off the unit and unplug the 
power cord from the AC outlet
. Remove the top cover
. For 120 VAC operation (pre-set 
condition), points "D" and "E" on the
printed circuit board (PCB) have been 
connected (shorted) with a flexible wire
jumper. To convert to 230 VAC input, 
disconnect the quick disconnect connector
at point "D" by pulling it upwards. Tape 
this end with an insulation tape and use
a cable tie to tie it securely to the 
wire harness running above
. The fuse on the AC side for the preset 
input voltage of 120 VAC is
rated at 250 V, 8 A. For 230 VAC 
operation, the fuse has to be rated at 
250 V,
4A. Replace the existing 8 A fuse with a 
4 A fuse. See under "SPECIFICATIONS"
on page 11 for details on the 4 A fuse.
.The detachable power cord that is 
provided has an "IEC 320-13"
female connector on one end that will 
mate with the "IEC 320-C14" male AC
inlet connector on the power supply. The 
other end of this power cord has a 120
VAC NEMA5-15P plug meant for connection 
to the 120 VAC, NEMA5-15R outlet.
For operation on 230 VAC, 50 Hz, a 
different detachable power cord will have to
be used. Use an appropriate power cord 
that has an "IEC 320-13" female
connector on one end (for connection to 
the "IEC 320-C14" AC inlet connector
on the power supply) and a 230 VAC plug 
on the other end corresponding to the
230 VAC outlet. Please ensure that the 
new 230 VAC power cord uses two pole,
3 wire grounding configuration (this 
will ensure proper earth grounding).
