4.2 MOUNTING AND PLACING OF THE INSTRUMENT

For a natural and correct cooling, the power supply must stand on its four rubber
thrusts and all ventilation openings must be widely cleared.
To connect the mains cord in the «EUROPE» CEE22 receptacle at the rear of the
instrument.

5. BEFORE USE

To connect the p. supply to mains (230V) and to switch on with the «On/Off» switch.

6. INSTRUCTIONS FOR USE

6.1 SAFETY INSTRUCTIONS

Any intervention inside the casing, and particulary the fuses replacement, must
!
imperatively be effectued by a skilled staff.
The instrument must be used according to the instructions of this manual.
The plug of the mains cord being used as the switch off device, the instrument
must be connected to a socket easily accessible, which has an earth connection.
When this instrument has to be powered using a separated autotransformer in
order to get a voltage reduction, make sure that the common terminal is
connected to the pole earthed of the feeding circuit.
The common mode voltage between Earth and output terminals shall not
exceed 50V rms. In this case, a voltage judged dangerous (>60Vdc) can be
reached between one of the terminals and Earth.
In series or tracking mode, a voltage of 60V (judged dangerous) can be
available between the positive terminal of the Master power supply and the
negative one of the Slave power supply.
In these cases, it is necessary to use safety cords for the connection to the
instrument's outputs. Moreover, the instruments connected mustn't give access
to conductive parts.

The lighting bipolar switch shows that the power-supply is on.
Directly earthed from the frame. Allows to take the earth as reference for your
mounting. This connection in not aimed to ensure the continuity of the
protective conductor.
SELECTION OF THE SEPARATED MODE
Allows the independant working of the A and B power-supplies.
VOLTAGE ADJUSTMENT
Allows the adjustment of a voltage between 0 and 30V.
VOLTAGE FINE ADJUSTMENT
Makes the voltage adjusted by (6) (31) vary of about 2V.
The lighting green Led shows that the power-supply works in voltage
regulation.
VOLTAGE DISPLAY
Allows to read the voltage from 0 to 30V with a 100mV resolution.
Allows to adjust a current between 0 and 3A.
