•
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.
•
Make sure there is no flammable material within a 0.5 m 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.
DMX-512 connection
•
When applicable, connect an XLR cable to the female 3-pin XLR output of a controller (not incl.) and
the other side to the male 3-pin XLR input [4] of the VDPL300CB. Multiple VDPL300CBs can be linked
through serial linking. The linking cable should be a dual core, screened cable with XLR input and
output connectors.
•
Maximum recommended serial data link distance is 500 meters (1640 ft). Maximum recommended
number of fixtures on a serial data link is 32 fixtures.
•
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 [5] of the last
device in the chain.
