For truss mounting, use an appropriate clamp (not incl.) and fit an M10 bolt through the centre of the
(folded) bracket.
Adjust the desired inclination angle via the mounting bracket and tighten the bracket screws.
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. If you do not use the power linking
feature, be sure to use the included screw-on cap to prevent any water from getting into the power
cords.
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 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 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.

The device can be used in the following modes:
stand-alone mode
