3.2. PREPARING FOR USE
APPLIANCE LOCATION
The temperature of environment must not be higher than
40°C and the relative humidity should be less than 85%.
Ensure good ventilation in the room in which the device
is being used. There should be at least 10 cm distance
between each side of the device and the wall or other
objects. The device should always be used when positioned
on an even, stable, clean, fireproof and dry surface, and
be out of the reach of children and persons with limited
mental and sensory functions. Position the device such that
you always have access to the power plug. The power cord
connected to the appliance must be properly grounded
and correspond to the technical details on the product
label.

3.3.2 OUTPUT VOLTAGE CHARACTERISTICS
1.
When the total output power (current x output
voltage) does not exceed the rated output power,
the power supply acts as a typical constant voltage
and current power supply device.
2.
When the total output power (current x output
voltage) exceeds the rated output power, the
effective output power is limited to the device's
power limit. In this case, the output current and
voltage depend entirely on the load value.
