the dimming curves to see which curve suits most for your needs. Of course you can also simply try the
dimmer curves... .
INSTALLATION AND OVERHEAD RIGGING
Important: The installation must be carried out by qualified service personal only. Improper
installation can result in serious injuries and/or damage to property.
Thanks to the multifunctional 19" adapters, the DSP4 can be
installed in 3 different ways:
19" RACK MOUNTING:
The most common way: you can install the unit easily in a
standard 19" rack using 4 rack bolts.
WALL MOUNTING:
You can mount the DSP4 easily against a wall as explained
below:
 Remove the 4 screws (marked "A" on the picture) on
both 19" adapters
 Turn the adapters over 180° as shown on the picture.
 Fasten the 4 screws again
 Fix the unit against the wall using suitable screws
(marked "B" on the picture).
IMPORTANT: since the ventilation holes are now
located on the side facing the wall, you MUST use
spacers to ensure at least 1cm between the unit and the
wall surface!
OVERHEAD RIGGING AND TRUSS MOUNTING:
 Important: Overhead rigging requires extensive experience! Working load limits should be
respected, certified installation materials should be used, the installed device should be inspected
regularly for safety.
 Make sure the area below the installation place is free from unwanted persons during rigging, de-rigging
and servicing.
 Locate the device in a well ventilated spot, far away from any flammable materials and/or liquids. The
fixture must be fixed at least 1cm from surrounding walls.
 The device should be installed out of reach of people and outside areas where persons may walk by or be
seated.

 Before rigging make sure that the installation area can hold a minimum point load of 10times the device's
weight.
 Always use a certified safety cable that can hold 12times the weight of the device when installing the unit.
This secondary safety attachment should be installed in a way that no part of the installation can drop
more than 20cm if the main attachment fails.
 The device should be well fixed; a free-swinging mounting is dangerous and may not be considered!
 The operator has to make sure that the safety-relating and machine-technical installations are approved by
an expert before using them for the first time. The installations should be inspected every year by a skilled
person to be sure that safety is still
optimal.
IN-TRUSS MOUNTING: thanks to the
size and shape of the DSP4 you can
install it inside ALU trusses (see picture)
and leave it there! To do this, follow the
steps below:
 Remove the 4 screws on both 19"
adapters
 Turn the adapters over 90° as
shown on the picture.
 Fasten the 4 screws again
 Put the DSP4 inside the truss and
use 2 hooks (for example our
CR50/LI) to fix it.
During transport the ALU truss will protect
the DSP4 and you will gain a lot of space
and setup time! 
CONNECTIONS
The unit is supplied with a power plug appropriate to its voltage and destination. Should any other
connections be required they must be carried out with the following configuration.
Earth = Green/Yellow cable
