It's the solution for a variety of applications, including art galleries, museums, retail displays, lobbies, comedy clubs, nightclubs, and hotel ballrooms. The OneTrack by ETC system includes an extensive selection of adapters, feeds, end caps, couplers, hanging accessories, and other accessories to meet most installation requirements.
About OneTrack Backbone OneTrack Backbone provides a robust track solution when larger fixtures are required. With OneTrack Backbone, an aluminum housing encloses OneTrack by ETC system hardware, providing additional strength and more robust structural attachment. A steel fixture hanger combined with a pigtail adapter allows you to use larger, theatrical lighting fixtures in addition to traditional track fixtures with OneTrack.

Safety Read and save these instructions before installing OneTrack, and refer to them when making additions to or changes in the OneTrack configuration. WARNING: RISK OF ELECTRIC SHOCK! Always disconnect electrical power before installation or maintenance of track or track components. AVERTISSEMENT : RISQUE DE CHOC ÉLECTRIQUE! Débranchez toujours l'alimentation électrique avant de procéder à...

• All hardware for attaching wire rope or threaded rod to appropriate building structure is the responsibility of the installing contractor. • Unauthorized modification of OneTrack or OneTrack components may void ETC warranty. • Do not use solvent, glue, oil, grease, or cleaner on any OneTrack components.
Planning Planning the Track Layout Consider the following elements as you plan your OneTrack or OneTrack Backbone track layout: • Track orientation: Each piece of track has a top and a bottom. The top of the track is oriented to the mounting surface, and the bottom is oriented toward the fixtures. •...
Install separate end feeds for DMX and power. • When planning for the locations of mid feeds, ETC recommends that you use mid feeds to provide power to the track, not DMX. (Using a mid feed to provide data creates a T- junction, which is disallowed.)

Suspended Physical Load Capacity The maximum weight that the track can support per linear foot varies based on the distance between mounting points. The following examples represent the maximum supported physical load based on various distances between mounting points. The distance shown at the top of each illustration is the distance between mounting points.
Install separate end feeds for DMX and power. • When planning for the locations of mid feeds, ETC recommends that you use mid feeds to provide power to the track, not DMX. (Using a mid feed to provide data creates a T- junction, which is disallowed.)

(unless you cannot avoid using the cut end with a coupler or feed accessory). • ETC recommends using a power miter saw with appropriate metal blade to cut the track. Figure 14: Use a power miter saw to cut track from the open side towards the top •...
Installation Methods OneTrack can be: • surface-mounted directly to a ceiling • surface-mounted to a wall • suspended by threaded rod, aircraft cable, or drop ceiling T-track A variety of mounting accessories are available. See OneTrack Mounting Accessories on page for more details.
Page 23
In applications where surface-mounting is not feasible, OneTrack Backbone provides most of the stability benefits of surface-mounting in a structure that can be suspension-mounted. OneTrack Backbone is compatible with standard strut beam clamps and other hardware that allow for robust connections to building structure. For suspension-mounting applications where the size of OneTrack Backbone makes it unsuitable or undesirable, you must install structural connection points to support joint positions as illustrated below.

• When using L-, T-, X-, I-, or Flex-Couplers (see OneTrack Accessories on page 33 ), use two-inch pendant clips to provide attachment points as close to the end of each connecting piece of track as possible. Use pendant clips to support track at each connection point Figure 18: Two-inch pendant clips for coupler support...
Surface Mounting (OneTrack Only) WARNING: RISK OF ELECTRIC SHOCK! Do not drill through the sides of the track. When surface mounting, ensure that the top of the track (opposite the opening) is mounted to the mounting surface. Do not mount the track sides to a mounting surface.
Cable Mounting (OneTrack Only) CAUTION: All hardware for attaching wire rope or threaded rod to appropriate building structure is the responsibility of the installing contractor. • Standard kits are available for suspension-mounting OneTrack with 1/16 in (1.5 mm) aircraft cables. See Five-inch Support Feed Kit on page 46 Five-inch Support Kit on page 47...
End of Track The end of OneTrack must be enclosed with a OneTrack end cap (part number 7076A1023). If you are using OneTrack Backbone, you must still enclose the end with the OneTrack end cap (as shown in the figure below), but you can also optionally install a OneTrack Backbone end cap (part number 7076A2017) for cosmetic purposes.
Reconfiguring DMX Data Lines Based on your system layout, you may need to reposition data lines. This is required for X-couplers, and may be necessary for T-couplers, too. This example demonstrates repositioning data lines for the X-coupler, but the same information applies to T-couplers (see Figure 23 Figure 24 ).

Installing End Feeds Tools Required on page 26 Before you begin, see When installing end feeds, be aware that DMX and power cannot be wired into the same end feed. Install separate end feeds for DMX and power. If you are using OneTrack Backbone, see the installation instructions provided with the End Feed OneTrack Backbone end feed housing to install the housing on the end feed.

Installing Current Limiters Tools Required on page 26 Before you begin, see Note: Current limiters can be used in DataTrack Backbone installations; however, the current limiters do not fit into the DataTrack Backbone housing. Current limiters are only surface mounted. POWER SOURCE NEUTRAL 2 CIRCUIT 2...
Troubleshooting Loss of Power WARNING: RISK OF ELECTRIC SHOCK! When working on electrical systems, turn off the breakers that are powering the track as well as the wall switches. Wall switches can be accidentally turned back on while you are working.
Data Issues Problem Troubleshooting Remedy Check track to be secured properly to mounting Use proper fastener to secure track. surface Check track to be level Spacers may be required to correct. Secure ends with proper fastener. Spacers may be used between ceiling and track to make the track Check track to be level.
