Capacitors inside the device may still be charged, even if the device has been
•
disconnected from all voltage sources.
Never switch on your DC/DC SPA-5 voltage converter if it has just been moved from
•
a cold to a warm room. Under unfavourable conditions, condensation water can form
and destroy your device. Leave the device off/disconnected and wait until it has
reached room temperature.
The ventilation slits of the DC voltage converter must not be covered! The devices
•
are to be placed on in
fl
ammable surfaces so that air can
fl
ow freely into the device.
The device is cooled mainly by convection.
During malfunction, voltages of > 35 V DC can be generated, which creates hazards.
•
This can happen even if the speci
fi
ed input/output voltages of the device are less.
Avoid operation under adverse ambient conditions. These can damage the sensitive
•
electronics inside the device. Adverse conditions are:
excess air humidity (> 80 % rel., condensing)
-
dampness
-
dust and in
fl
ammable gases, vapours or solvents, petrol
-
excessive ambient temperatures (> approx. +50 )
-
strong electromagnetic (motors or transformers) or electrostatic (charges)
fi
elds
-
Keep transmitters (mobile telephones, transmitter units for model building etc.) away
•
from the DC/DC voltage converter to prevent transmitter emissions from interfering
with the operation of or destroying the converter.
Do not connect any 12 V DC batteries to the outlet of the device because the outlet is
•
not short circuit-protected in case of incorrect polarity, which will destroy the device.
The minimum input voltage must not be less than 21.0 V DC!
•
The maximum input voltage must not exceed 28.8 V DC!
•
When used in conjunction with other devices, observe the operating instructions and
•
safety notices of connected devices.
The product must not be subjected to heavy mechanical stress.
•
The product must not be exposed it to extreme temperatures, direct sunlight, intense
•
vibration, or dampness.
If there is reason to believe that safe operation is no longer possible, put the device
•
out of operation and secure it against unintended operation. Safe operation is no
longer possible if:
the product shows visible damages,
-
the product no longer works and
-
the product was stored under unfavourable conditions for a long period of time,
-
the product was subject to considerable transport stress.
-
Miscellaneous
Repair works must only be carried out by a specialist/ specialist workshop.
