Figure 5-31 Layout of aisle lights
(1) Light tube
A light tube is 872 mm long. Determine the distance (W) between a light tube and a side of the aisle
based on the actual length of the contained aisle in the module: W = (L – 872 x N)/2. L is the actual
length of the contained aisle. N is the number (round down the value of L/872) of light tubes installed in
a single row. Round down the value of W.
A light tube has male and female connectors at both ends for interconnection, as shown in
Figure 5-32. When installing lights, ensure that all the male connectors face the same
direction (also the female connectors) for serial connection of light tubes.
Issue 04 (2017-06-30)
A maximum of 12 aisle lights can be connected in series. If the number exceeds 12, they should be
installed in different groups.
Redundant light tubes are delivered.
Grouping rule: Divide into equal groups if possible and ensure that the light cables are routed out of
the nearby cable holes in skylight plates.
