Physical Installation; Standing Installation; Flying From A Truss, Bar Or Other Structure - Martin LC 2140 User Manual

Physical installation

Warning!Use two clamps attached to conical couplers to rig each panel. Secure with two
approved safety cables, looping one cable around each vertical side column. Do not use the
LED tubes as secondary attachment points.
Hang a maximum of seven attached panels vertically. If a curtain more than seven panels high is
required, a new curtain must be hung from another supporting structure.
The LC 1140/2140 can be installed in a standing position, flown in a vertical curtain or suspended in any
orientation from a truss or supporting structure.

Standing installation

Important! Do not place LC 1140/2140 panels directly on a flat surface, as this will block the flow
of air to the air vents in the base and cause overheating.
If you install panels in a standing position:
1. Make sure that there will be at least 0.1 m (4 in.) of free space and unrestricted airflow to and around the
air vents in the base of the panels. One option is to install panels on stands or trusses placed on the
surface.
2. Check that any structure or equipment used for support can bear at least 12 times the weight of all the
panels, clamps, cables, auxiliary equipment, etc. that will be placed on it.
3. Check that there are no combustible materials within 0.5 m (20 in.) of the panels when installed, and that
there are no flammable materials nearby.
4. Secure the tops of panels so that they cannot fall over and cause damage or personal injury.

Flying from a truss, bar or other structure

To fly panels from a rig or other structure:
1. Check that the structure can bear at least 12 times the
weight of all the panels, clamps, cables, auxiliary
equipment, etc. that it will have to support.
2. See Figure 4. Check that the structure will not flex under
the weight of the panels. Hanging panels from a structure
that is not straight will place a strain on panels. Damage
caused to panels by mechanical stress is not covered by
the product warranty.
3. Check that there are no combustible materials within 0.5
m (20 in.) of the panels when installed, and that there are
no flammable materials nearby.
4. Install two conical couplers in the top of the first panel
and install two rigging clamps or eyebolts on the
couplers.
5. Block access under the work area. Working from a stable
platform, hang the panel by fastening the rigging clamps
or eyebolts to the truss or structure.
6. As soon as a panel is fastened in place, install two safety
cables to secure it. Safety attachments must be able to
bear at least 12 times the weight of all the panels they
secure. Loop safety cables in a figure-of-eight around
vertical side columns so that if a rigging clamp or conical
connector fails, the weight of the panels will be held by
the vertical columns and the blocks the columns are
anchored in, and not by the panel bases or top rails.
