General Guidelines
Refer to the Velleman® Service and Quality Warranty on the last pages of this manual.
This stroboscope should only be used indoors with an alternating current of max. 230 V~, 50 Hz.
Do not shake the device. Avoid brute force when installing or operating the device.
Select a location where the device is protected against extreme heat, dust and moisture. Respect a
minimum distance of 0.5 m between the device's light output and any illuminated surface.
Familiarise yourself with the functions of the device before actually using it. Do not allow operation
by unqualified people. Any damage that may occur will most probably be due to unprofessional use
of the device.
Use the original packaging if the device is to be transported.
All modifications of the device are forbidden for safety reasons.
Only use the device for its intended purpose. All other uses may lead to short circuits, burns,
electroshocks, lamp explosion, crash, etc. Using the device in an unauthorised way will void the
warranty.
4.
Installation
The installation construction should be able to support a minimum point load of 10 times the weight
of the device.
The installation must always be secured with a secondary attachment e.g. a safety cable (VDLSC7 or
VDLSC8).
Never stand directly below the device when it is being mounted, removed or serviced. Have a
qualified technician check the device once a year and once before you bring it into service.
Overhead mounting requires extensive experience: calculating workload limits, determining the
installation material to be used... Have the material and the device itself checked regularly. Do not
attempt to install the device yourself if you lack these qualifications as improper installation may
result in injuries.
The installation has to be approved by an expert before the device is taken into service.
The glass pane has to be replaced when it is damaged.
