Mains Operating Voltage

This instrument has a universal input range and will operate from a nominal 115V or 230V mains

supply without adjustment. Check that the local supply meets the AC Input requirement given in

the Specification.

Mains Lead

When a three core mains lead with bare ends is provided this should be connected as follows:

BROWN - MAINS LIVE

BLUE - MAINS NEUTRAL

GREEN/YELLOW - EARTH Safety Earth Symbol

When fitting a fused plug a 5 amp fuse should be fitted inside the plug. 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 shown above 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 black.

The wire which is coloured brown must be connected to the terminal which is marked with the

letter L or coloured red.

WARNING! THIS INSTRUMENT MUST BE EARTHED.

Any interruption of the mains earth conductor inside or outside the instrument will make the

instrument dangerous. Intentional interruption is prohibited.
