10 MAC Encore™ Performance Safety and Installation Manual
Clamping the fixture on a truss
1. Check that all rigging hardware is undamaged and can bear at least 10 times the weight of the fixture or
as required by locally applicable regulations. Check that the supporting structure can safely bear the
weight of all installed fixtures, clamps, cables, auxiliary equipment, etc. and complies with locally
applicable regulations.
2. Bolt each rigging clamp securely to an omega bracket with an M12 bolt (minimum grade 8.8) and
self-locking nut.
3. See Figure 4 on page 9. Align the first clamp
and bracket with 2 mounting points in the base,
and engage both the clamp bracket’s
quarter-turn fasteners in corresponding sockets
in the base. See Figure 5. Turn the levers on
the quarter-turn fasteners a full 90° clockwise
to lock. Repeat for the second clamp.
4. Block access under the work area. See Figure
6. Note the position of the arrow marked
FRONT on the base of the fixture. Working
from a stable platform, hang the fixture on the
truss with the arrow marked FRONT facing
towards the area to be illuminated. Tighten the
rigging clamps.
5. See Figure 7. Install a safety cable that is
approved as a safety attachment for the weight
of the fixture by looping it through the safety
attachment point (arrowed) in the bottom of the
base and around a secure anchoring point so
that the safety cable will catch the fixture if a primary attachment fails. Remove as much slack as
possible from the safety cable (by looping it twice around the anchoring point, for example).
6. Check that the tilt lock is released. Check that
there are no combustible materials within 0.2 m
(8 in.) or surfaces to be illuminated within 2.0 m
(6.6 ft.) of the fixture, and that there are no
flammable materials nearby.
7. Check that there is no possibility of heads or
yokes colliding with other fixtures. Note that
pan and tilt range on the MAC Encore
Performance can be limited via the control
panel to allow fixtures to be installed closer to
each other or to obstacles with no risk of
collision (see User Guide for details).
8. Check that other lighting fixtures cannot project
light at the MAC Encore Performance, as
powerful illumination can damage the fixture’s
display.
