Installation
Choose a suitable mounting spot. Mount the device in the desired angle using the included bracket.
Connect the power cord to the mains. Disconnect after use.
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.
For truss mounting, use an appropriate clamp (not incl.) and fit an M10 bolt through the centre of the
(folded) bracket.
The installation must always be secured with a secondary attachment such as a safety cable
(e.g. VDLSC7N or VDLSC8N). The secondary attachment shall be designed and mounted in such a
way that no part of the device can fall if the primary attachment fails.
Make sure that the safety cables can carry 10 times the weight of the device. Make sure that the
maximum height of drop is limited so that no injuries can occur. If the safety cables are long, wrap
them around the truss multiple times to reduce the height of drop to a safe level.
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.
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. All devices must be powered directly off a
grounded switched circuit and cannot be run off a rheostat or dimmer circuit, even if the rheostat or
dimmer channel is used solely for 0 % to 100 % switching.
The device has a power output to supply power to another device. When connecting several devices
in a daisy chain via this output, make sure that the total current does not exceed the power line’s
nominal current. Use power cables with an adequate section. 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 XLR output of a controller (not incl.) and the
other side to the male XLR input of the device. Multiple devices can be linked through serial linking.
The linking cable shall 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 devices on a serial data link is 32 devices.
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 120 Ω
resistor between pins 2 and 3, which is then plugged into the XLR output socket of the last device in
the chain.
