Mounting Base-down and Base-up
All Thunder enclosures are designed to be mounted base-down, on a solid structure, using Unistrut
mounting hardware. They may also be suspended from an overhang, ceiling or truss, using the
same hardware.
It is the responsibility of the installer to ensure that all mounting points are secure and conform to
local safety regulations. Tempest Lighting Inc. accepts no responsibility for damage or injury
arising from inappropriate or unsafe installation.
Drainage
Drainage holes are provided in the top and bottom of the enclosure. The holes in the cover (top) are
plugged with 10-32 screws and sealing washers.
Important – Drainage in base-up installations:
1
Remove the drainage plug screws from the cover
