Mounting with rigging clamps
To install the impression E350 in any orientation on a rigging
truss or similar support:
See Figure 9. Pass two M10 grade 8.8 steel bolts or screws
through two half-coupler type rigging clamps and check
that the bolts will protrude minimum 9 mm / 0.35 in. and
maximum 11 mm / 0.43 in. into the base of the fixture
when tightened.
See Figure 8. Fasten the bolts through the half-coupler
clamps and into holes A in the base of the fixture so
that the clamps are held securely.
Fasten the rigging clamps securely around a chord on a rigging truss or similar bar.
Secure the fixture with a safety cable as described in 'Safety attachment' on page
20.
Make sure that the head will not collide with another fixture or any other object
when it moves through its full pan and tilt ranges.
Safety attachment
If the impression E350 may cause
injury or damage if it falls, you
must secure it with a secondary
attachment such as a safety
cable. To install a safety cable:
Obtain a safety cable that is
approved for the load it will
secure.
See Figure 10. Fasten the
safety cable to one of the
safety cable attachment
points in the base of the
fixture and loop it around a
secure anchoring point such
as a truss chord. Remove as
much slack as possible in the safety cable (by looping it more than once around
the truss chord, for example).
Secure the safety cable and check that it will hold the fixture if a primary
attachment fails.
