3. General Guidelines
•
Refer to the Velleman® Service and Quality Warranty on the last pages of this manual.
•
Familiarise yourself with the functions of the device before actually using it.
•
All modifications of the device are forbidden for safety reasons. Damage caused by user
modifications to the device is not covered by the warranty.
•
Only use the device for its intended purpose. Using the device in an unauthorised way will
void the warranty.
•
Damage caused by disregard of certain guidelines in this manual is not covered by the
warranty and the dealer will not accept responsibility for any ensuing defects or problems.
•
Keep this manual for future reference.
•
The device enjoys optimal protection thanks to the short-circuit protection and the current-
limiting point. The power loss in case of short circuit is limited thanks to the protection
circuit that controls the power loss of the transistors in the power supply. This feature
keeps the device from being damaged. The device will automatically go into the current-
limiting mode, which means that the current-limiting point (max. ± 12 A) is installed.
Nevertheless, the short circuit should be repaired as soon as possible in order to prevent
wear and unnecessary power consumption.
•
The output will be cut off if the short-circuit occurs between the positive and the negative
output terminal, which prevents power loss. The device will resume normal operation when
the problem has been solved.
•
This device is a large power source. The device should be well-ventilated when working at
max. power in order to avoid overheating. Keep in mind that the surface of the heat sink is
too hot to touch when the device is being used at max. power.
•
Improper operation of the device and an excessive ambient temperature may cause certain
internal components to fail. When this happens, the actual output voltage may exceed the
rated output voltage. Proceed with caution when using this device and avoid unnecessary
damage to the load.
