GENERAL INSTRUCTIONS

Thank you for purchasing this stabilized power supply.
This instrument complies with IEC norm 61010-1, concerning electronic measuring
instruments. For your own safety and to protect the instrument, you should comply with the
instructions in this manual which cannot be reproduced in any form whatsoever without our
agreement.
1.1.

Precautions and safety measures

1.1.1. Before use

∗
This power supply complies with the IEC 601010 safety norm, class 1, pollution level 2. It
has been designed for indoor use at altitudes below 2,000 m and at temperatures between
0° C and 50° C with a relative humidity < 80% up to 40° C.

• Mains power supply:
∗
Definition of installation categories (see IEC publication 664-1):
CAT I: CAT I circuits are circuits protected by low-level transient over-voltage limiters
Example: protected electronic circuits
CAT II: CAT II circuits are household or similar appliance power circuits, which may carry
medium-level transient over-voltages.
Example: household appliance and portable tool power supplies
CAT III: CAT III circuits are high-power appliance power circuits, which may carry high-level
transient over-voltages.
Example: industrial machinery or instrument power supplies
CAT IV: CAT IV circuits are circuits which can carry substantial transient over-voltage.
Example: power feeders
∗
To use this power supply safely, users must comply with the customary safety rules
in order to:
∗
For your safety, only use the lead delivered with the instrument. Before using it, always
check that it is in perfect condition. It must be connected to the mains before
connecting measurement or control circuits.
∗
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.
Before connecting the power supply, check that the information on the label on the rear of
the power supply corresponds to the 115 V
network.
