ERA 500 Hybrid IP Safety and Installation Manual
Clamping the fixture to a truss
1. Check that all rigging hardware is undamaged and can bear at least six (6) 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 2 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 3. 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 4. The
front of the fixture is the side opposite the cable tails and
is indicated with an arrow on the base of the fixture.
Working from a stable platform, hang the fixture on the
truss with the front facing towards the area to be
illuminated. Tighten the rigging clamps.
5. See Figure 5. Install a safety cable that is approved as a
safety attachment for the weight of the fixture by looping
it through the safety cable 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 more than
once around the truss bar, for example).
6. Check that there are no combustible materials within 0.2
m (8 in.) or surfaces to be illuminated within 10 m (33 ft.)
of the fixture, and that there are no flammable materials
nearby.
7. Check that there is no possibility of the head colliding
with objects or other fixtures.
8. Check that other lighting fixtures cannot project light at
the ERA 500 Hybrid IP, as powerful illumination can
damage the fixture’s display, seals and pressure relief
valves.
