3.1 Electrical Preparation
 All electrical work must be carried out by a properly licensed electrician. Failure to observe this
point will void the factory warranty for the Tempest Enclosure and possibly the equipment housed
inside.
1 Before starting work, switch off power to the branch circuit, carefully following lockout and tag-out
procedures. Failure to do so could cause serious injury or death.
2 Two electrical junction boxes will be required within a short distance of the Twister enclosure for:
 AC supply wiring
 DMX control wiring
Your Twister enclosure is supplied fitted with two cable entry points, for Power and DMX signal cables.
The cable entries are suitable for use with standard conduit fittings. US size ½”, international 20mm.
Tempest recommends the use of flexible, outdoor-rated conduit for the last few feet (1m) to the enclosure.
All junction boxes must be installed in accordance with local electrical codes and should be located near the
permanent installation of the enclosure. Each junction box requires a length of flexible conduit, long
enough to reach from the junction box to the enclosure conduit fittings. Leave slack for positioning of
enclosure, and enough space behind the enclosure for ventilation.
The AC supply must be protected by a fuse or circuit breaker of a rating suitable for the equipment.
The user may connect the fan and the equipment to the same switched supply, or run them separately,
according to need (see below).
Note that for temporary installation, the conduit fittings may be replaced with outdoor-rated cable entry
glands, at the user’s discretion.
