DANGER!
Hazardous voltage
Hazardous voltage may be present at cable ends and screw terminals.
The connection of screw terminals as well as all maintenance and repair work on
the electrical installation of the device must only be performed by qualified electrical personnel in volt-free condition. Failure to do so may result in electric shock
and risk of fire and loss of life.
By all means you have to observe all electrical safety instructions applicable at the
place of operation.
The device is designed for mounting in 19" racks, it occupies two rack units (RU).
If necessary, install a CEE plug on the power cord of the unit.
First, connect the loads to the terminals on the back of the device. Establish the DMX link to
the controller. Finally, connect the CEE plug of the device to a CEE socket.

Connect the DMX input of the device to the DMX output of a DMX controller or other DMX
device. Connect the output of the first DMX device to the input of the second one and so on,
to form a series connection. Make sure that the output of the last DMX device in the chain is
terminated by a resistor (110 Ω, ¼ W).

8 Plug and connection assignments
This chapter will help you select the right cables and plugs to connect your valuable equipment so that a perfect light experience is guaranteed.
Please take our tips, because especially in ‘Sound & Light’ caution is indicated: Even if a plug
fits into a socket, the result of an incorrect connection may be a destroyed DMX controller, a
short circuit or ‘just’ a not working light show!
The unit offers a 3-pin XLR socket for DMX output and a 3-pin XLR plug for DMX input. Please
refer to the drawing and table below for the pin assignment of a suitable XLR plug.
