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.)
