100 Series User Manual
Referring to the illustration below, fasten the center of the yoke with a 12 mm (1/2 inch) shaft diameter bolt
in the center hole
A . Then use two bolts with 8 mm (5/16 inch) shaft diameter passing through the curved
slots B to anchor the fixture. Use washers and locking nuts. This setup will give approximately 90° of pan
adjustment.
Mounting yoke base dimensions
Suspending from a truss
In temporary installations, you can suspend the fixture from a rigging truss by means of a rigging clamp
that is approved for the weight of the fixture securely fastened through the hole in the center of the yoke
base (
A in illustration above). The fixture must be installed hanging vertically downwards only.
When using a rigging clamp, secure the fixture with a safety cable (or similar secondary attachment) that
is approved for the weight of the fixture so that the safety cable will hold the fixture if the rigging clamp
fails. Loop the safety cable through the safety cable attachment point on the back of the fixture (see
‘Fixture overview’ on page 9). Remove as much slack as possible from the safety cable (by looping it more
than once around the truss chord, for example).
Check that the truss and all fasteners used can support 10 times the weight of all the fixtures and
equipment that they will support.
Adjusting tilt
Warning! The fixture can become hot. Wear heat-resistant gloves if you adjust the
aim of the fixture when it is (or has recently been) powered on.
Tilt adjustment can be carried out with the fixture powered on as
follows.
1. Put on heat-resistant gloves.
2. See illustration on right. Loosen, but do not remove, the tilt lock
screws (arrowed) on both sides.
3. Tilt the fixture to the desired angle and retighten the screws.
