3 Precautions for use

3.1 Avoid extreme temperatures
Do not leave the power supply directly exposed to sunlight or a source of heat,
for example a radiator, for an extended period.
Do not use the appliance when it is cold: its operating temperature must be
between 0°C and 40°C.
Avoid sudden movement of the power supply from a warm to a cold place and
vice versa, otherwise there is a risk of condensation forming inside the
appliance.
3.2 Avoid damp and dust
If the power supply is located in a very damp or dusty place, operating
problems can be expected. The range of relative humidity recommended is 35
to 90%.
3.3 Handle with care
Avoid placing the power supply in a place exposed to strong vibrations or there
may be a failure of the appliance. Avoid placing the appliance close to
magnetic items or in a place exposed to a high intensity magnetic field. The
galvanometer is sensitive to induced magnetic fields.
Avoid placing objects directly on the appliance or obstructing the ventilation
holes.
