replacement. The use of makeshift fuses and the short-circuiting of fuse holders is prohibited.
Mains Lead
When a three core mains lead with bare ends is provided this should be connected as follows:
BROWN
BLUE
GREEN/YELLOW
As the colours of the wires in the mains lead of this apparatus may not correspond with the
coloured markings identifying the terminals in your plug proceed as follows:
The wire which is coloured green-and-yellow must be connected to the terminal in the plug which
is marked by the letter E or by the safety earth symbol or coloured green or green-and-yellow.
The wire which is coloured blue must be connected to the terminal which is marked with the letter
N or coloured blue or black.
The wire which is coloured brown must be connected to the terminal which is marked with the
letter L or coloured brown or red.
If the unit is to be connected to the main supply by fixed wiring, rather than via an AC line plug,
then the protective earth (ground) wire in the 3 core mains lead shall be connected to a protective
conductor before any other connection is made.
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.
Rack kits for mounting supplies in a 19" rack are available from the Manufacturers or their
overseas agents.
All connections are made from the front panel.
The load(s) should be connected to the positive (red) and negative (black) terminals marked

Remote sense connections to the load, if required, are made from the positive (red) and negative
(black) SENSE terminals. The shorting links between OUPTUT and SENSE terminals should be
removed when remote sensing is required. Replace the shorting links (red SENSE to red
