•
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.
Installation:
•
Fix the Truss hooks (1) to the Omega clamps with screw and locking nut.
•
Fasten the omega clamps (2) on the bottom of the base by inserting quick-lock fasteners (3) into the holes
of the base and tighten fully clockwise. (you should hear or
feel a ‘click’)
1 = Omega Clamps
2 = Holes for Safety cable
ELECTRICAL INSTAL ADDRESSING
Important: The electrical installation should be carried out by qualified personal only,
according to the regulations for electrical and mechanical safety in your country.
Electrical installation for two or more units in DMX-mode:
•
The DMX-protocol is a widely used high speed signal to control intelligent light equipment. You need to
“daisy chain” your DMX controller and all the connected units with a good quality balanced cable.
•
Both XLR-3pin and XLR-5pin connectors are used, however XLR-3pin is more popular because these
cables are compatible with balanced audio cables.
Pin layout XLR-3pin: Pin1 = GND ~ Pin2 = Negative signal (-) ~ Pin3 = Positive signal (+)
Pin layout XLR-5pin: Pin1 = GND ~ Pin2 = Negative signal (-) ~ Pin3 = Positive signal (+) ~ Pins4+5 not used.
•
To prevent strange behavior on the DMX units, due to interferences, you must use a
90Ω to 120Ω terminator at the end of the chain. Never use Y-splitter cables, this
simply won’t work!
•
Make sure that all units are connected to the mains.
•
Each unit in the chain needs to have its proper starting address so it knows which
commands from the controller it has to decode. In the next section you will learn how to set the DMX
addresses.
