Check that the instrument operating voltage marked on the rear panel is suitable for the local
supply. Should it be necessary to change the operating voltage, proceed as follows:
1) Disconnect the instrument from all voltage sources.
2) Remove the screws which retain the top cover and lift off the cover.
3) Change the connections on both transformers following the appropriate diagram below:
4) Refit the cover and the secure with the same screws.
5) To comply with safety standard requirements the operating voltage marked on the rear panel
must be changed to clearly show the new voltage setting.
6) Change the fuse to one of the correct rating, see below.
Fuse
The AC fuse is located in the fuse drawer in the lower part of the IEC inlet connector. To change
the fuse remove the line cord and open the fuse drawer with a suitable too.
The correct mains fuse type is 20 x 5mm 250V HBC time-lag with the following rating:
In addition, the two transformers are individually fused inside the power supply. To access these
fuses remove the cover as described above; both fuses are clipped to the small PCB which is
fitted directly onto the pins of the IEC inlet connector itself.
The correct fuse type is 20 x 5mm 250V HBC time-lag with the following rating:
Make sure that only fuses with the required current rating and of the specified type are used for
replacement. The use of makeshift fuses and the short-circuiting of fuseholders are prohibited.
Mains Lead
Connect the instrument to the AC line using the three-core mains lead provided.
Any interruption of the mains earth conductor inside or outside the instrument will make the
instrument dangerous. Intentional interruption is prohibited. The protective action must not be
negated by the use of an extension cord without a protective conductor.
Mounting
This instrument is suitable both for bench use and rack mounting. It is delivered with feet for
bench mounting. The front feet include a tilt mechanism for optimal panel angle.
A rack kit for mounting XDL Series power supplies is available from the Manufacturers or their
overseas agents. The rack will accommodate 1, 2 or 3 single units or a triple and single unit; a
blanking piece is also available for unused positions in the rack.
Ventilation
The power supply is cooled by an intelligent multi-speed fan which vents at the rear. Take care
not to restrict the air inlets at the side panels or the exit at the rear. In rack-mounted situations
allow adequate space around the instrument and/or use a fan tray for forced cooling.
