HANGING
Hanging Preparation
Observe the following guidelines when installing truss equipment.
Luminaire Orientation and Placement
Luminaire hanging orientation is usually denoted on a lighting plot. A lighting plot is created in advance and
represents the stage setup and desired location and orientation of luminaires.
Luminaires and repeaters are generally hung from pipes or trusses, and suspended above the object of illumination.
Ensure that minimum distance safety requirements are observed. The minimum distance symbol can be found on the
input rating label of luminaires and specifies the minimum safe distance from the front lens to a lighted object.
Luminaire input (pigtail) cables are used as reference points when hanging instruments. The hanging orientation of the
luminaire on the truss or pipe determines which direction the luminaire will initially move from the luminaire zero
position when the pan and tilt controls are manipulated from the console. All luminaires move to their zero position
when they finish calibration (head and yokes half-way between stops). The input cables should have an order: all
pointed stage left or stage right, or downstage luminaires one way and upstage luminaires the other. This allows the
luminaires to move in a like manner when all luminaires are selected and moved at the same time.
Truss Pipe
Normally, Series 200 luminaires are hung with two truss hooks on a single pipe. Series 300 luminaires are hung with
one double truss hook or clamp (VL7) on a single pipe. The hooks fit securely on any pipe with an outer diameter
between 1 and 2 inches (25.40 to 50.80 mm). The clamp is designed for a 2 inch (50.80 mm) pipe. The use of square
pipe is not recommended. Other truss-mounted equipment may only require one S200 truss hook. Truss hooks are
clamped to the pipe (or truss) by turning the wing bolt, installed in one of two threaded holes. (The wing bolt should be
tightened only by hand.)
