This is an ITE Class A product. In a domestic environment this product may cause radio interference in
which case the user may be required to take adequate measures.
Unpacking
LC Series products are packaged either in sets of 4 panels in a 4-unit flightcase or as single panels in a
cardboard box. The following items are included:
• In the 4-unit flightcase: 16 conical connectors and 24 threaded spigots, four flightcase castors (two with
brakes) with mounting screws
• In the cardboard box: 4 conical connectors and 6 threaded spigots
• This user manual
Important! Do not throw away the protective shock-absorbing materials from the flightcase when you
unpack the panels. The protective strips will be needed when panels are repacked in the
flightcase (see
“Packing panels in the flightcase” on page 9).
Using for the first time
Before applying power to the panel:
• Carefully review “Safety Information” on page 3.
• Check that the local AC power voltage is within the ranges listed on the serial number label and in “Power
and main fuses” on page 13.
• To supply the panel with power, install a Neutrik PowerCon NAC3FCA connector on a listed, minimum 12
AWG or 2.5 mm2 SJT (or better) power cable as described in “Power connection” on page 13.
8 LC 1140/LC 2140 user manual
Packing panels in the flightcase
Important! To ensure that LC 1140/LC 2140 panels can withstand the shocks that normally occur during
transport, they must be packed in a Martin flightcase and transported in an upright position as
described in this section. Damage caused to panels that are incorrectly packed or exposed to
abnormal shocks is not covered by the product warranty.

When removing panels from the flightcase, keep all protective material for use when repacking.
When repacking panels in the flightcase:
1. Insert panels with the clear LED tubes facing the front of the flightcase as shown in Figure 2, and
2. Insert the protective strips supplied with the flightcase so that the channel in each strip faces the front of
the flightcase and slides over the clear plastic brackets as shown in
Figure 3.

Figure 3: Protective strip orientation
Important! When transporting a flightcase that is not full, pack panels from the front without leaving gaps,
so that any empty slots are at the back of the flightcase. Transport and store flightcases
standing in an upright position o nly. Do not transport flightcases lying flat on th eir si de.
Introduction 9
Physical installation
Warning!Use two conical couplers to fasten a panel to a supporting structure or to another
panel – never use only one conical coupler. Secure with two approved safety cables, looping
one cable around each vertical side column. Do not use the LED tubes as secondary attachment
points.
When stacking panels one on top of another or suspending panels one from another, do not
exceed the limits given in Figure 4. If an installation needs to be taller than the limits gi ven in
Figure 4, additional support points must be provided to bear the weight of the additional panels.
The LC 1140/LC 2140 can be installed in a standing position alone or stacked, flown in a vertical curtain or
suspended in any orientation from a truss or supporting structu re.

Figure 4: Safety limits for stacking and suspending attached panels
Standing installation
Important! Do not place LC 1140/LC 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.

See Figure 4. One vertical stack with LC 1140 panels resting on each other may contain a maximum of 10
LC 1140 panels stacked upright or 9 LC 1140 panels stacked on their sides.
One vertical stack with LC 2140 panels resting on each other may contain a maximum of 8 LC 2140 panels
stacked upright or 6 LC 2140 panels stacked on their sides.
An unlimited number of stacks of panels may be installed alongside each other.
If you install panels in a standing position:
1. Check that any structure or equipment used for support can bear at least 10 times the weight of all the
panels, clamps, cables, auxiliary equipment, etc. that will be placed on it.
2. 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.
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. Fasten panels securely so that they cannot tip or fall.
10 LC 1140/LC 2140 user manual
Flying from a truss, bar or other structure
See Figure 4. One vertical cur tain with LC 1140 panels suspended from each other may contain a
maximum of 9 panels. One vertical curtain with LC 2140 panels suspended from each other may contain a
maximum of 7 panels. These limits apply to panels both when suspended in an upright position and when
suspended on their sides.
An unlimited number of curtains of panels may be installed
alongside each other
To fly panels from a rig or other structure:
1. Check that the structure can bear at least 10 times the
weight of all the panels, clamps, cables, auxiliary equipment,
etc. that it will have to support.
2. See Figure 5. 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 10 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.
7. See Figure 6. Continue hanging panels, attaching them with
conical couplers (A) secured with threaded spigots (B) as illustrated. As soon as a panel is added to an
array, secure it with two safety attachments.
