Mounting Guide, Tempest Enclosures
These guidelines are intended as a general guide only. Users may adapt them to suit local conditions
and objectives. It is the responsibility of each user to secure engineering and safety approvals as
required under local regulations, prior to commencing construction. Tempest Lighting, Inc., its
employees and agents, will not be responsible for any errors or defects in installations whatsoever,
resulting from inadequate interpretation of these guidelines.
Most Tempest enclosures are provided with two strips of
stainless steel UnistrutTM channel on their underside. Only the
Unistrut strips are load-rated for structural support of the
enclosure and its contents. No other mounting point is to be
Tempest recommends the use only of stainless steel mounting
Any suitable standard Unistrut fittings may be used to attach the
enclosure to a structure. While Unistrut is readily available in
many countries, in some parts of the world it can be hard to

For this reason, Tempest markets several Unistrut adapter kits:

4900.MM Stainless Steel
Unistrut channel nut, bolt

4900.MC Stainless Steel
Unistrut channel nut, bolt
and pipe clamp, for pipes

per enclosure.
Generally, Tempest enclosures will be
mounted either atop a pole or structure, or
suspended below a beam or truss.
In many cases, it is helpful to fabricate a
stainless steel plate (say 5-6mm (3/16-1/4”)
thick) to attach to the structure and provide
mounting points for the enclosure. Such plates
will generally be square, with four mounting
holes (13mm or 0.563”) for the Channel
mounting bolts.

Poles and Posts
Depending on height above ground, and the total weight of the enclosure and equipment housed,
steel posts and poles of different dimensions may be used to mount Tempest enclosures.
This illustration shows a projector enclosure
atop a pole with a sloping mounting plate. The
plate angle roughly corresponds to the desired
direction of the projection beam, with the fine
adjustment being done using the projector’s
own mechanical and electronic adjustments
inside the enclosure. Note that cable entry for
all Blizzard and Cyclone projector enclosures,
as well as Thunder lighting enclosures, is on
the enclosure’s rear panel.
With Tornado
moving light enclosures, note that the cable entry ports are in the
center of the enclosure base. Therefore you must either allow a hole in
the middle of the mounting plate to allow wiring conduit access, or
incorporate spacers between the mounting plate and the Unistruts.
Incorporating a hole in the center of the
mounting plate, as shown here, allows for
the conduits feeding power and control
cables to run inside the post, for a clean
and uncluttered installation.
For flexibility and ease of installation, we
recommend the use of separate, outdoorrated, flexible conduits to connect power
and control/signal wiring to Tempest
enclosures. More details are included in
the installation manual for your Tempest
enclosure. All electrical installations must be performed by a qualified
electrician, and in compliance with local electrical and building
Many other installation configurations are possible – this guide is
intended only to acquaint designers of mechanical mounting methodology.
