Mounting Options
CAUTION
Restrict the access under the work area during rigging and/or derigging.
You can mount the device in 2 different ways:
●to a rigging bar (LED screen below a rigging bar/ LED screen on top of a rigging bar)
●to a truss
Mounting the Device to a Rigging Bar
Hanging Installation
By the hanging installation, the device is installed below a rigging bar.
WARNING
Do not hang more devices than the maximum allowed number on one rigging bar.
The rigging bars are designed for hanging installation of 18 LED screens under each other. Do not hang
more than 18 LED screens under each other on one rigging bar.
WARNING
Do not mount the device to a rigging bar only by the magnet.
The LED screen and the rigging bar have magnetic strips. The magnetic strips are designed to help you
align the device to a rigging bar during installation.
●Make sure that the device is always held until installation is completed.
●Do not let the device hang on a rigging bar only by the magnet.
Before you start the installation of the LED screens, make sure that the rigging bar setup is leveled, as
shown in Fig. 15 and 16. For more information about leveling, see the user manual of the Single Rigging
Bar/ Double Rigging Bar (101820/101821) (101820/101821).
