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

Connect the instrument to the AC supply using the mains lead provided. Should a mains plug be
required for a different mains outlet socket, a suitably rated and approved mains lead set should be
used which is fitted with the required wall plug and an IEC60320 C13 connector for the instrument
end. To determine the minimum current rating of the lead-set for the intended AC supply, refer to the
power rating information on the equipment or in the Specification.
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 very efficient but nevertheless can generate significant heat at full power.
The supply relies on convection cooling only and it is therefore important that ventilation is never
restricted if performance and safety are to be maintained.
All connections are made from the front panel.
The load should be connected to the positive (red) and negative (black) terminals marked
OUTPUT. Connect to one or both outputs as appropriate for the selected Mode, see Operation
section.
Warning! Voltages above 70Vdc are hazardous live according to EN 61010-1 and great care must
be taken when using the power supply at voltages above this level.
The universal safety binding posts used for the output meet the requirements for reinforced
insulation for voltages up to 250Vdc because creepage and clearance to the terminal contacts is
>2.5mm even with the binding post fully open. However, it is highly recommended that the binding
posts are usually fully tightened and that connections are only made using leads fitted with
fixed-shroud 4mm safety plugs. Make sure that the circuit to which connections are made
is appropriately insulated; no accessible parts of the external circuit should become
hazardous live in normal or single fault condition as defined by EN61010-1.
Always make connections to the instrument with the OUTPUT off.
