Mains Operating Voltage
The operating voltage of the instrument is shown on the rear panel. Should it be necessary to
change the operating voltage from 230V to 115V or vice-versa, proceed as follows:
1.
Disconnect the instrument from all voltage sources.
2.
Remove the screws which hold the case upper to the chassis and lift off.
3.
Turn the unit over and support the weight of the power supply PCB while removing the six
screws which hold it to the chassis. Leave the pillars attached to the PCB.
4.
Fit the soldered links (alongside the transformer) for the required operating voltage:-
These links may be either tinned copper wire or zero-ohm resistors.
5.
Refit the power supply PCB to the chassis, ensuring that no wires are trapped. Check that
all cables are correctly connected.
6.
Refit the case upper.
7.
To comply with safety standard requirements the operating voltage marked on the rear
panel must be changed to clearly show the new voltage setting.
Fuses
There are no user replaceable fuses in the instrument.
Mains Lead
When a three core mains lead with bare ends is provided it should be connected as follows:
Any interruption of the mains earth conductor inside or outside the instrument will make the
instrument dangerous. Intentional interruption is prohibited.
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 one or two of these half-width 3U high units is available from the
Manufacturers or their overseas agents; a blanking piece is also available for unused positions in
the rack.
Ventilation
The unit is cooled by two 2-speed fans which vent at the rear. Take care not to restrict the air
inlets at the top, side and bottom 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.
If ducting is applied to the air outlet, additional extraction is required.
