When repacking panels in the flightcase:
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.
Front
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 only. Do not transport flightcases lying flat on their side.
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 given 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 structure.

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.
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 curtain 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.
Figure 5: Avoiding stress on panels
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.

Diffuser
A diffuser may be fastened to the panel, respecting the diffuser manufacturer’s safety precautions. Installing a diffuser gives a softer rendition of the video image, eliminating the ‘hot-spot’ effect.
Threaded holes for fastening a diffuser front are provided next to the holes for
the conical coupler system. See Figure 7
for dimensions.
Single LED tubes
If you install panels angled away from each other, you will be left with a gap in the LED tubes at the apex of the angle.
To fill this gap and give a solid wall of
LEDs, it is possible to install a single
LED tube between two panels. This tube must be connected to the Aux. Out connector on the connections panel.
If you are interested in this solution, contact your Martin supplier for details.

AC power
Warning! Read “Safety Information” on page 3 before connecting an LC 1140/LC 2140 panel to
AC power. Lock out power to the entire distribution system before carrying out installation work.
Important! Do not supply the panel with power via an external dimming system, or you may cause damage to the panel that is not covered by the product warranty.
Power and main fuses
Warning! Replace fuses with ones of the same type and rating only.
The LC 1140/LC 2140 features an auto-sensing switch-mode power supply that automatically adapts to
100-120 V and 200-240 V nominal AC power at 50 or 60 Hz. Connect the panel to AC power that is within these voltage ranges only.
Power circuits in both LC1140 and LC 2140 screens are protected by three 5 amp slow-blow main fuses
and changing a main fuse.
C u r r e n t f l u c t u a t i o n
slightly on a cycle of approximately one minute, especially at voltages over 200 V. Peak current draw is unlikely to occur at exactly the same time in multiple fixtures, but to avoid unintentional tripping of circuit-breakers, allow a safety margin of at least 20% when calculating the current requirements of an LC
1140/LC 2140 installation.
Power connection
Warning! For protection from electric shock, the panel must be grounded (earthed). Power distribution circuits must be fitted with a current overload fuse or circuit breaker and ground-fault (earth-fault) protection.
Warning! The total current draw of all devices connected via one power input socket, including the first panel connected, must not exceed 20 amps.
Warning! Use only a power cable that is listed, 12 AWG or 2.5 mm
2
, SJT (or better) and power connectors that are listed, rated 20 A minimum.
Warning! The power socket/outlet must be installed near the LC 1140/LC 2140 and must be easily accessible so that the LC 1140/LC 2140 can easily be disconnected from power if necessary.
Power is supplied to the panel via the input socket. This socket accepts a blue Neutrik PowerCon NAC3FCA cable connector.
Power can be relayed to another device via the output socket. This socket accepts a light-grey PowerCon
NAC3FCB cable connector. The total current drawn by devices that are interconnected by relaying power, including the first panel, must not exceed 20 amps. This means that, with a safety margin of 20%, a maximum of five LC 2140 panels or ten LC 1140 panels may be connected together at 230 V, for example.
Current draw figures for LC 1140/LC 2140 panels are given in “Typical power and current” on page 32.
PowerCon connectors and suitable power cables with PowerCon connectors installed are available from your Martin supplier.
AC power 13
The Neutrik PowerCon NAC3FCA and NAC3FCB power cable connectors used with the LC 1140/LC 2140 accept power cable from 5 mm (0.20 in.) to 11 mm (0.43 in.) diameter when fitted with a white chuck, or from 9.5 mm (0.4 in.) to 15 mm (0.6 in.) diameter when fitted with a black chuck.

you have any doubts about proper installation, consult a qualified electrician.
To plug a PowerCon connector in, line up the raised tab on the cable connector with the keyway in the chassis connector, push the cable connector in and twist clockwise to lock. To remove the connector, pull back the latch to release the lock, twist the connector counterclockwise and pull out.
There is no power on/off switch on LC panels. Apply and shut down power using an external switch at the power outlet or at the main switchboard. Make sure that the external switch is near the panels and easily accessible so that power to the panels can easily be shut down if necessary. Do not power panels on or off by inserting or removing live PowerCon connectors, as this will cause arcing at the connector contacts that will damage devices and connectors.
Important!
Shut down power to all panels and devices before connecting or disconnecting any element on the video link, or you may damage your graphics card or other video components.
Shut down power to PowerCon connectors before inserting or removing them.
Apply power to the LC panels (and monitor, if used) before you apply power to the media server, or you may damage the panels’ video circuitry.
14 LC 1140/LC 2140 user manual
Video link
LC Series panels accept a 1024 x 768 XGA DVI-D single link (digital and DDC) signal and will display a 25x25 (LC 1140) or 25x50 (LC
2140) pixel image.
Each panel has two DVI connectors on its connections panel: one for
video input and one for video output. See Figure 9. Although the
video signal is DVI-D single link, the connectors are DVI-I dual link type. The advantage of this solution is that any DVI cable can be used, although only the pins that carry the DVI-D single link signal are actually used.
An output labelled AUX is also provided for one extra LED tube that can be added to fill the gap in a video curtain if panels are installed angled away from each other.
The LED labelled DVI on the connections panel lights when a valid video signal is being received.

Figure 9: DVI connectors
Planning the video link
Figure 10 and Figure 11 show examples of video link layout. The following elements are involved:
Media server: We recommend the use of the Martin Maxedia™ for its advanced features and intuitive user interface.
Important!
The media server’s graphics card must be set to send a video signal with a 50 or 60 Hz refresh rate, as LC 1140 and 2140 screens accept only these rates.
DVI buffer box: You need a buffer box on the link if the following functions are required:
1. 1024 x 768 DVI monitor emulation. The Maxedia ‘expects to see’ a monitor on each of its outputs. The
DVI buffer box emulates a 1024 x 768 DVI monitor, allowing a Maxedia to operate correctly, and relays the DVI signal to the rest of your installation.
2. Genlock synchronization of your installation via the buffer box’s BNC connector. The Martin DVI Buffer
Box also has a jumper that allows matching with a 50 or 60 Hz refresh rate.
3. Communication (reading installed software version, uploading new software, etc.) between the LC
Series management application running on a PC and video panels via the buffer box’s RS-232
connector. See “Advanced setup” on page 24 for the full list of functions.
DVI splitter: A splitter is required to send the video signal to more than one panel. It duplicates the video signal and sends it to two or more DVI devices. Splitters affect the quality of the DVI signal so there are limits to the number of devices that can be connected to successive generations (connecting a panel to a splitter
Figure 11 creates a further generation).
Important!
If a DVI splitter is used, the DDCCLOCK and DDCDATA signals on pins 6 and 7 of the DVI input must be relayed to each of the splitter’s DVI outputs if you want a PC to communicate with the panels connected to that output. Many DVI splitters relay the DDCCLOCK and DDCDATA signals

DVI monitor: A monitor is required to view the video image in parallel with the array of LC panels.
Important!
The monitor must accept a DVI-D signal with a 50/60 Hz refresh rate.

Connecting the video link
Important!
Media server graphics cards, LC panel video circuits and other components on the video link are sensitive and can easily be damaged by differences in potential. Observe the precautions listed below, or you may cause damage that is not covered by the product warranty:
1. Shut down power to all panels and devices before connecting or disconnecting any connector on the video link.
2. When inserting DVI connectors, ensure that the metal shields around the outside of male and female connectors make contact before the pins. This will provide a path to ground (earth) for any difference in potential between devices or components.
3. Apply power to the LC panels (and monitor, if used) before you apply power to the media server.
4. When you shut down the entire installation, power the media server off before you cut power to the LC panels and monitor.
To maintain signal quality, the DVI cable between any splitter and the first panel connected to it must be maximum 5 m (16.5 feet) long.
To connect the video link:
1. Power all panels and devices off while making connections.
2. Connect the DVI output from the source (Martin Maxedia, for example) to a DVI buffer box.
3. Connect the DVI output from the DVI buffer box to the DVI input on a DVI splitter.
4. If you want to monitor the video image, connect the first DVI output from the splitter to your DVI monitor.
5. Connect the next DVI output from the splitter to either a second DVI splitter or the first panel’s DVI input socket using a DVI cable max. 5 m (16.5 ft.) long.
6. Continue adding splitters or panels, connecting DVI output to DVI input and respecting the layout and guidelines explained earlier in this section.
7. When you have made all connections, set up the panels as described in the next section of this manual before applying power first to the panels (and DVI monitor, if used) and then to the other devices.

Panel setup
This section describes how to set panels to display a video image.
Video image resolution
Because LC 1140 panels can only display 25 x 25 pixels and LC 2140 panels can only display 25 x 50 pixels, to map every pixel in a 1024 x 768 pixel video image to a single pixel in a video curtain would require a very large installation with 41 panels horizontally and either 31 LC 1140 or 16 LC 2140 panels vertically.
This arrangement would give full 1024 x 768 resolution with a few spare pixels at the edges.
Your installation probably has a smaller number of panels than this, so you can set up the output from your media server in two ways:
• You can display an area of the video image that has the same number of pixels as your installation at full pixel resolution (one pixel in the installation displays one pixel of the video image). The advantage of this is that you do not lose any detail from this area of the image, but the disadvantage is that you can only display part of the video image.
• You can display an area of the video image that has more pixels than your installation, but at reduced pixel resolution (one pixel in the installation displays an “average” of more than one pixel in the video image).
The advantage of this is that you can display more of the video image than in the first method, but because you only have a limited number of pixels in your installation, you must accept loss of detail from the video image.
If you have a limited number of LC panels, you are thus faced with a trade-off between the amount of the video image you display and the amount of detail that is possible: the more of the video image you display, the less detail you can display. To take an extreme example of this, it is possible to display a full 1024 x 768 video image on one LC panel, but you have to accept a very significant reduction in video image resolution and loss of detail.
To reduce the resolution of a full 1024 x 768 video image, ‘shrink’ the image on your monitor screen until it contains the same number of pixels as your installation. For example, to display a full 1024 x 768 video image on an installation 200 pixels (8 panels) wide and 150 pixels (6 x LC 1140 panels or 3 x LC 2140 panels) high, you must ‘shrink’ the image to just under 20% of its original size, so that it fits in an area on your monitor screen 200 pixels wide and 150 pixels high.
Note that LC panels cannot ‘shrink’ a video image themselves – ‘shrinking’ must be carried out on the media server.
If your installation has the same aspect ratio as the video image (e.g. 1024 x 768, 800 x 600, 400 x 300, 200 x 150 pixels etc. for a 4:3 aspect ratio image), you can display the full video image using all the pixels in your installation. However, the smaller your installation is, the more you must ‘shrink’ the video image, reducing its resolution and thus the amount of detail you can display.
Tiles in the video image
The DVI signal on the video link contains the full video image information everywhere on the link, so each panel on the link receives the full video image. One panel can display only a small part of the full image, however, so each panel divides the video image into
25 x 25 pixel “tiles” as shown in Figure 12, and then
displays one or two tiles:
• an LC 1140 panel displays one tile
• an LC 2140 panel displays two tiles – one tile plus the tile below it.
25pix
Setting panels to display tiles
To identify individual tiles, a panel gives each tile an x and a y coordinate according to the following principles:
• Coordinates are numbered starting at the top left-hand corner of the video image when facing the video image.
• The top left-hand tile is given the coordinates x = 0, y = 0.
Figure 12: Tiles in the video image
• The next tile to the right is one tile further along the x axis, so it is given the coordinates x = 1, y = 0. After this tile, the next tile to the right is assigned the coordinates x = 2, y = 0, and so on.
• The tile below the top left-hand tile is one tile further down the y axis, so it is given the coordinates x = 0, y = 1. The next tile down is assigned the coordinates x = 0, y = 2, and so on.
18 LC 1140/LC 2140 user manual
To set a panel to display a specific part of the video image, you set the x and y coordinates of the tile you want it to display:
• An LC 1140 panel will display that 25 x 25 pixel tile
• An LC 2140 panel will display that 25 x 25 pixel tile plus the 25 x 25 pixel tile below it.
See Figure 13. Address setting is carried out on the panel’s DIP
switch. The DIP switch has 12 pins that are numbered from the right:
• Pins 1 to 6 are used to select the tile position on the x axis.
• Pins 7 to 12 are used to select the tile position on the y axis.
y coordinate x coordinate
Numbers are set on DIP switches in binary form (1 = 0 0 0 0 0 1 ,
2 = 0 0 0 0 1 0 , 3 = 0 0 0 0 1 1 , 4 = 0 0 0 1 0 0 , etc.). You set the binary number for the x coordinate on pins 1 - 6 and set the binary number for the y coordinate on pins 7 - 12.
For example, to set the x coordinate 17 and the y coordinate 14 on a DIP switch, you must first convert these coordinates to binary numbers (17 = 0 1 0 0 0 1 , 14 = 0 0 1 1 1 0 ), then set the dip switch

Figure 15: Mapping LC 2140 and 1140 panels from the top left corner of the image
because they are different heights. Both types of panel are addressed starting with y = 0, but:
• setting the y coordinate to zero maps an LC 2140 panel to the top row (if you set DIP switch pins 7 - 12 to
0, the panel displays the rows with y coordinates 0 and 1), and
• setting the y coordinate to zero maps an LC 1140 panel to the second row (if you set DIP switch pins 7 -
12 to 0, the panel displays the row with y coordinate 1).
Note that an LC 1140 panel cannot be mapped to the top row of the video image.
If the principle behind mapping and addressing is confusing, just refer to the DIP switch settings shown in
LC 1140/LC 2140 user manual
Panel addressing – an example
Here is an example of how to set an array of panels so that each panel displays the correct tile in the video image. Let us say that:
• You have installed twenty-four LC 2140 panels in a curtain eight panels wide and three panels high, giving you 200 x 150 pixels in your installation.
• You have ‘shrunk’ the image you want to display to 200 x 150 pixels on your monitor screen.
• You have positioned this 200 x 150 pixel image approximately in the center of your monitor (positioning in the center of the monitor may not be absolutely necessary, but it usually gives more cropping and resizing options in your media software).
You now need to set the addresses of your panels so that they display a block of 25 x 25 pixel tiles that is
200/25 = 8 tiles wide and 150/25 = 6 tiles high, positioned approximately in the center of the 1024 x 768 video image.
See Figure 16. In the full video signal, the x axis is approximately 41 tiles wide and the y axis is
approximately 32 tiles high. The tile with x coordinate 21 and y coordinate 16 is in the approximate center of the video image.
20 21

block in the center of your monitor, you must give them the x and y coordinates shown in the illustration.

Figure 17: Displaying tiles in center of video image (LC 2140)
LC 1140/LC 2140 user manual
If LC 1140 panels are used to display the same pixels from the video image, they must be set as shown in
Note that with LC 1140 panels, you must set the y coordinate to the number of the row on the y axis minus
one (i.e. to locate an LC 1140 panel on row 16 of the y axis, you must set its y coordinate to 15).
Figure 18: Displaying tiles from center of video image (LC 1140)
Video link 23
Tips for panel addressing
You may find the following tips helpful when setting addresses on panels:
• Remember that if you have LC 2140 panels in your installation, you must set y coordinate addresses to
14, 16 and 18 to obtain a correct video image.
• As mentioned earlier, when setting the y coordinate of an LC 1140 panel, remember that you must subtract 1 from the row on the y axis where you want to locate that panel (for example, set the y coordinate on an LC 1140 panel’s DIP switch to 15 if you want that panel to display a tile on row 16 on the
y axis.
• If you are mixing LC 2140 and LC 1140 panels in an installation, bear in mind that LC 1140 panels cannot be set to display the top row (row with y coordinate zero) in the video image – this row can only be displayed with LC 2140 panels.
• You can save time converting decimal to binary numbers by using one of the many free converters available on the Internet.
• After setting the addresses of the panels in an installation, you may need to do a little fine adjustment to the position of the pixel image on your monitor to align it precisely with your group of panels.
Advanced setup
Using the Martin LC Series DVI Buffer Box (P/N 91611269) and a PC with the LC Series management application (included with the buffer box), the following operations can be carried out via the video link:
• Viewing the software version currently installed in each panel in an installation.
• Uploading new software to panels in an installation.
• Genlock via the buffer box’s BNC connector
• Brightness adjustment for an individual panel
• Global brightness adjustment for a complete installation
• Video image freeze-frame from the PC application
Full details and instructions covering these operations are included with the DVI buffer box.
24 LC 1140/LC 2140 user manual
Operation
If the system is correctly set up, operation is simply a question of displaying video from the media server or other DVI video source.
During operation, four LED indicators on the connections panel give information about the status of the panel and the video signal:
• The Power LED lights when power is applied to the panel.
• The Pulse LED flashes when the system controller is running. The flash rate is 1/16 of the signal frequency (at 50 Hz, 20 flashes take approx. 12 seconds). The LED flashes slowly when there is no signal.
• The Error LED should not light during normal operation. It lights constantly if there is a fault in the video signal or panel. The Error LED has a secondary function: it flashes when there is communication between a PC and the panel.
• The DVI LED lights when the panel is receiving a valid DVI signal.
Operation 25
Service and maintenance
Warning! Read “Safety Information” on page 3 before carrying out service or maintenance work
on the LC 1140/LC 2140. Lock out power to the entire distribution system before servicing, cleaning or removing any cover. Refer any service operation not described here to a qualified service technician.
Important! Excessive dust, smoke fluid, and particle buildup degrades performance, causes overheating and will damage the panel. Damage caused by inadequate cleaning or maintenance is not covered by the product warranty.
As with electronic components in general, the LC 1140/LC 2140’s PCBs are sensitive to ESD
(electrostatic discharge). Take precautions to avoid ESD damage during service.
It is Martin policy to use the best quality materials available to ensure optimum performance and the longest possible component lifetimes. However, optical components in all lighting fixtures are subject to wear and tear over the life of the fixture, resulting in gradual changes in color rendition, for example.
The extent of wear and tear depends heavily on operating conditions, maintenance and environment, so it is impossible to specify precise lifetimes for optical components. However, you will eventually need to replace the LEDs in the LC 1140/LC 2140 if their characteristics are affected by wear and tear after an extended period of use and if you require panels to perform within very precise optical and color parameters.
To maximize the life of the LC 1140/LC 2140 and protect the investment it represents, clean the panel regularly – especially the cooling fans and grilles – following the guidelines in this section.
Cleaning
Regular cleaning is essential for product life and performance. Buildup of dust, dirt, smoke particles, fog fluid residues, etc. degrades the panel’s light output and cooling ability.
Cleaning schedules for lighting fixtures vary greatly depending on the operating environment. It is therefore impossible to specify precise cleaning intervals for the LC 1140/LC 2140. Cooling fans suck in airborne dust and smoke particles, and in extreme cases panels may require cleaning after surprisingly few hours of operation. Environmental factors that may result in a need for frequent cleaning include:
• Use of smoke or fog machines.
• High airflow rates (near air conditioning vents, for example).
• Presence of cigarette smoke.
• Airborne dust (from stage effects, building structures and fittings or the natural environment at outdoor events, for example).
If one or more of these factors is present, inspect panels within their first 25 hours of operation to see whether cleaning is necessary. Check again at frequent intervals. This procedure will allow you to assess cleaning requirements in your particular situation. If in doubt, consult your Martin dealer about a suitable maintenance schedule.
Do not use abrasive, caustic or solvent-based products for cleaning, as they can damage plastic or painted surfaces.
To clean the panel:
1. Disconnect the panel from power and allow it to cool for at least 10 minutes.
2. Vacuum or gently blow away dust and loose particles from the fan blades and grilles in the base of the panel with compressed air.
3. Wipe the outside of the LED tubes with a soft, lint-free cloth dampened with a solution of water and detergent or auto shampoo. Apply gentle pressure only.
If the inside surfaces of the LED tubes require cleaning, remove the tubes, slide the LED circuit boards out
of each tube as described in “Replacing LED tubes” on page 28
, and blow through with compressed air. If necessary, flush each tube with a warm water/detergent solution. Dry thoroughly with compressed air before reassembling.

Fuse replacement
Warning! Disconnect from power before opening covers. Replace fuses with ones of the same type and rating only.
Important! The PCBs are sensitive to ESD (electrostatic discharge). Take precautions to avoid
ESD damage. Avoid touching electronic components.
LC 1140 and LC 2140 panels are protected by three 5 amp slow-blow fuses on the three power supplies in the panel base.
To replace a fuse:
1. Disconnect the panel from power and allow to cool for 10 minutes.

4. Reinstall the cover before reapplying power.
Service and maintenance 27
Replacing LED tubes
To replace an LED tube:
1. Disconnect the panel from power and allow to cool for 10 minutes.
2. See Figure 20. Insert a broad flat-blade
screwdriver into the slot in each of the clear plastic brackets immediately behind the tube you want to remove. Twist the screwdriver very slightly to release the tube in the slot so that it can be pulled forward out of the bracket.
3. See Figure 21. When the tube is released from
all brackets, bend it outwards at the center (A and B) until the top of the tube is clear of the retaining bracket (C).
4. Pull the top of the tube forward (D) just enough for the tube to clear the retaining bracket. Do not pull the tube further forward than is necessary.
5. Lift the tube upwards (E), holding the PCB at the bottom of the tube so that it is unplugged from the base as the tube is lifted (F). Be careful not to damage the connector terminals on the
PCBs while handling.
6. Slide the PCBs out of the tube for access to the LEDs.

Figures apply with all LEDs at max. intensity. Figures are valid at nominal voltage and are typical averages, not maximum. Current draw may fluctuate at approx. 1 cycle per minute, especially at 200 V and above.
Current fluctuation will not occur at the same cycle in all panels, but to avoid unintentional tripping of circuit breakers, add a 20% safety margin when calculating the current capacity of the power distribution system.
