 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,
crash, etc. Using the device in an unauthorised way will void the warranty.
4. Mounting the Device
 Have the device installed by a qualified person, respecting EN 60598-2-17 and all other applicable norms.
 The carrying construction must be able to support 10 times the weight of the device for 1 hour without deforming.
 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.
 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.
 Adjust the desired inclination angle via the mounting bracket and tighten the bracket screws.
 Make sure there is no flammable material within a 0.5m radius of the device.
 Have a qualified electrician carry out the electric connection.
 Connect the device to the mains with the power plug. Do not connect it to a dimming pack.
 The installation has to be approved by an expert before the device is taken into service.
5. Use
a. DMX512 mode
DIP Switch Setting
Pull down in the arrow direction to turn on. The address switch shown on
the diagram is preset as “1”.
DMX512 Connections
Connect an XLR cable to the female 3-pin XLR output of your controller and the other side to the male 3-pin
XLR input of the VDP1500LFM. Multiple VDP1500LFMs can be linked through serial linking. The linking cable
should be two core, screened cable with XLR input and output connectors.
DMX512 Chain with Terminator
A DMX terminator is recommended for installations where the DMX cable has to run a
long distance or is in an electrically noisy environment (e.g. discos). The terminator
prevents corruption of the digital control signal by electrical noise. The DMX terminator is
simply an XLR plug with a 120Ω resistor between pins 2 and 3, which is then plugged into
the XLR output socket of the last device in the chain.
Please see illustrations to the left.
DMX512 Start Address Selection
All DMX-controlled devices need a digital start address so that the correct device responds to the signals. This
digital start address is the channel number from which the device starts to “listen” to the DMX controller. Enter
the correct number and read it from the display located on the backside of the VDP1500LFM.
You can use the same starting address for a whole group of devices or enter an individual one for every
device.
