
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.

For truss mounting, use appropriate clamps and brackets.

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 [6] 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 [2] 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 [5] of the last
device in the chain.
8. Operation
The device can be used in the following modes:

stand-alone mode: automatic or sound-activated

master/slave

with a DMX-512 controller.
