3. General Guidelines
• This device is designed for professional use on stage, in discos, theatres, etc. The VDP250SC4EHJ should only
be used indoors with an alternating current of max. 230VAC / 50Hz.
• Lighting effects are not designed for permanent operation: regular operation breaks will prolong their lives.
• 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 (see "Technical Specifications"), dust and
moisture. Respect a minimum distance of 0.5m between the device's light output and any illuminated surface.
• Use an appropriate safety cable to fix the device (e.g. VDLSC7 or VDLSC8).
• 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
a) Lamps
• Only fit or replace a lamp when the device is unplugged from the mains.
• Let a lamp cool down before replacing it as the temperature of a lamp can reach 700°C during operation.
• When handling a halogen lamp, do not touch it with your bare hands. Use a cloth to insert or remove it.
• Do not install lamps with a higher wattage. They get hotter than this device was designed for.
• Replace any deformed or damaged lamp with a lamp of the same type (see "Technical Specifications"):
1. Unscrew the 2 thumb-screws holding the fan plate at the bottom, and gently flip the fan plate over.
2. Unscrew the 2 thumb-screws holding the plate with the lamp socket.
3. Remove the old lamp and insert the new one.
4. Carefully reposition the lamp socket and fasten the 2 thumb-screws.
5. Reposition the fan plate and fasten its 2 thumb-screws.
Remark: Do not operate the device when the cover is open.
b) Fuse
• Only fit or replace a fuse when the device is unplugged from the mains.
• If the lamp burns out, chances are you will need to replace the fuse as well.
• Replace a blown fuse with a fuse of the same type and rating (see "Technical Specifications"):
1. Unscrew the fuse holder cap at the back, below the power connector.
2. Remove the old fuse and install a new one.
3. Replace the fuse holder cap in the housing.
c) Mounting the Device
• Have the device installed by a qualified person, respecting EN 60598-2-17 and all other applicable norms.
• The construction to which the device is attached should be able to support 10 times the weight of the device for
one hour without deformation.
• The installation must always be secured with a secondary attachment e.g. a safety cable.
• 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.
• Install the device in a location with few passers-by that is inaccessible to unauthorised persons.
