28 VDO Face 5™ user manual
• You must install connection plates on all four corners of every panel above the lowest 10 panels in a
column.
• You can install columns up to 10 panels high in an array without corner connection plates, provided that
the panels are connected side-to-side.
• Each header must be suspended from minimum two cables or chains.
Two-column arrays
• If you hang two columns of panels from a double header without fastening them side-to-side to other
panels (see C in Figure 24), you must suspend the header using three cables or chains: one cable or
chain per eyebolt on all three eyebolts on the double header.
Four-column arrays
• If you hang four columns of panels from two double headers without fastening the four-column array
side-to-side to other panels (see D in Figure 24), you must suspend the double headers using minimum
four cables or chains: one cable or chain per eyebolt on minimum two eyebolts per double header.
Three- and five-column arrays
• If you add a single column of panels to one of the above to create an array of three or five columns of
panels, the same guidelines apply as for larger multiple-panel arrays:
- If you want to add a single column of panels that is not fastened to other panels at both sides (as in H
in Figure 25), you must obtain a single header and install on it an additional eyebolt available from
Martin®. Then you must suspend the single header from two cables or chains before you hang the
single column from it.
- If you want to install a single column that is fastened to other panels at both sides (as in G in Figure 9),
you may use a single header without and additional eyebolt and suspend it from one cable or chain.
To create an array consisting of 2 - 5 columns of panels:
1. See Figure 24. Obtain enough headers for all the columns, and obtain enough corner connection plates
available from Martin® to stabilize the column. You will need two connection plates for each panel above
the lowest 10 panels.
2. Suspend the headers in a row from the truss or other supporting structure. Suspend each header from
its central eyebolt using a cable or chain that is approved to support ten times the total weight of the
header and all the items that will hang from it. Each eyebolt must have its own cable: do not loop one
cable through more than one eyebolt. Make sure that there is no slack in cables: all cables must be
equally tight. Each time you add a header, fasten it to the previous header with a header side connection
bracket.
3. Install panels one by one in rows under the headers as described in “Instructions for suspending panels”
on page 32. Each time you add a panel, fasten it using both its vertical fastener posts, then fasten it
side-to-side immediately. Install corner connection plates on all four corners of every panel that will have
10 panels or more suspended below it.
4. Attach the array to anchoring points at its lower corners to make it impossible for the bottom of the array
to move. Do not apply downward force to the array when attaching it.
