WARNING IMPORTANT
This appliance must be earthed.
The wires in the mains lead are coloured in accordance with the following code:
Green and yellow
Blue
Brown
If the plug provided is unsuitable for socket outlets, the plug must be cut off and suitable plug fitted.
The cut-off plug should be disposed of and must not be inserted into any 13 amp socket as this can
result in electric shock. The plug or adapter or the distribution panel should be provided with 13
amps fuse. As the colours of the wires in the mains lead of this appliance may not correspond with
coloured markings identifying the terminals in your plug, proceed as follows:
The green and yellow wire must be connected to the terminal in the plug which is marked with the
letter E or by the earth symbol, or coloured green, or green and yellow.
The blue wire must be connected to the terminal which is marked with the letter N or coloured black.
The brown wire must be connected to the terminal which is marked with the letter L or coloured red.
NOTE: After replacing or changing a fuse, the fuse cover in the plug must be replaced with a fuse
cover which corresponds to the colour of the insert in the base of the plug or the word that is
embossed on the base of the plug, and the appliance must not be used without a fuse cover. Only 13
Amps fuse approved to B.S. 1362 A.S.T.A. should be used.
Switch on the power. Each time the instrument is turned on a self diagnostic test is done. If an error is
detected during the test a message will appear on the display and an alarm will sound.

4. Technical description

4.1 Front panel

The front panel consists of an alphanumeric display, a keyboard with 9 membrane keys, a light emitting
diode (LED) that lights when voltage is applied (HV on) and connectors for two electrophoresis units.

4.1.1 Display

A 32 digit alphanumeric display guides you through the programming, shows current parameter values
during the electrophoresis and final parameter values afterwards. It also asks questions and shows error
messages. The display has an upper and lower row.
Fig. 1 (inside front cover) shows the display in the start position when power is switched on for the first
time. The mode (in this case SET) is shown in the upper row on the left. The program number is in the
center of the upper row. The number shown is that of the previously entered program. As no program
has yet been entered, the first available program number, P1, is shown. The blinking figure, in this case
"1", indicates that it can be changed by using the
breakpoint. In this case it is off.
The lower left, middle and right positions show voltage, current and power respectively.
