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 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.
Install aisle lights in parallel. Connect the first and last light tubes on aisle sides in series.
Install the light tubes on the skylight plates. The BOM number of aisle lights is
52220591.
A light tube has male and female connectors at both ends for interconnection. When
installing lights, ensure that all the male connectors face the same direction (also the
female connectors) for serial connection of light tubes.
Lights are installed in the same way in both single-row and dual-row aisle containments.
This section describes how to install lights in a dual-row aisle containment.
