Triple output power supply
General Instructions (cont’d)
∗
Any break in the protective conductor, inside or outside the
instrument, or disconnection of the protective earth terminal may
make the instrument dangerous. Intentional breaking is prohibited.
∗
When this instrument is supplied via an autotransformer in order to
reduce the external voltage, make sure that the common terminal is
connected to the neutral (earthed pole) of the supply circuit.
∗
The plug should only be inserted into a socket equipped with an
earthing contact. The safety connection must not be broken by
use of an extension lead without a protective conductor
.
When using the
instrument
∗
When the required voltage and current parameter values are not
known, start by using the lowest values.
∗
Before disconnecting the connection leads of the circuit being
tested, make sure that the power supply is switched off. This
prevents the creation of break or closure extra-currents which
may melt the fuse at high currents.
∗
Never exceed a total output of 60 V peak in relation to the earth
(common mode).
∗
The instrument must be placed in a ventilated room. Take care
not to obstruct the ventilation holes.

instrument
Instructions
∗
Before opening the instrument, disconnect if from all sources of
electric current and from the measuring circuits; make sure that you
are not charged with static electricity, which could irreparably
damage the instrument's internal components.
∗
Before opening the power supply to change the fuse, you must
disconnect the leads and mains power supply cable. The fuse must
be replaced by a model identical to that delivered with the instrument.
∗
When the instrument is open, some of the internal capacitors
may conserve a dangerous potential, even once the instrument
has been powered down.
In the event of faults or abnormal
constraints, power down the instrument and do not allow anyone to
use it until it has been checked.
∗
Adjustments, maintenance or repair work on the instrument must
only be carried out by qualified personnel.
∗
A
"qualified person"
is someone who is familiar with the
installation, the construction, the application and the dangers at
hand. This person is authorised to power up and power down the
installation and equipment, in compliance with safety regulations.
Caution : refer to the manual. Incorrect use may damage the
instrument and endanger the user.
