Power Supply Operating Manual 42V 10A

Installation

Mains Operating Voltage

Check that the instrument operating voltage marked on the rear panel is suitable for the local

supply.

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.

Ventilation

The power supply is cooled by a low-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.

Connections

All connections are made from the front panel.

The load should be connected to the positive (red) and negative (black) terminals marked

OUTPUT.

Remote sense connections to the load, if required, are made from the positive (+) and

negative (−) SENSE terminals. Switch the LOCAL/REMOTE switch to REMOTE when remote

sensing is required. Switch back to LOCAL when remote sensing is not in use.

The terminal marked

is connected to the chassis and safety earth ground.
