Planning First

Plan the layout by measuring the design layout and dividing by 8 ft . (2.44m) to determine the required quantity of Tetra Contour. Refer to the Cutting Resolution Table on page 2 when cutting any Tetra Contour section. Do not use more than one suffix code for each respective application, as mixing suffix codes may result in appearance variation. Suffix code can be found on the packaging label. Installation methods shown are for straight runs. For custom shapes, refer to the Light Guide Forming Instructions. DO NOT bend the light engine to an inside radius that is tighter than 3/4 in. (19mm). The light engine is not intended for excessive or repetitive bending or stretching. If the silicone does crack, electrical grade silicone can be applied to seal the crack. If you have any questions about these instructions or your specific Contour application, please contact support at tetra.support@gecurrent.com

Installation

1. Install a minimum of one clip per 18 in. (457mm) using #10 (M4) screws.

2. Using the light guide final length, measure out the necessary length of Contour LED light engine to match. If required, using a sharp cutting tool, cut wire loops between sections or through light engine (refer to the Cutting Resolution Table on page 2).

3. Push the light engine segments down into the light guide.

4. For vertical or near vertical installations, any cut-end termination of a Contour piece shall reside at the top of the design.

5. Attach Tetra Contour to the mountingclips, leaving a 3/8 in. (10mm) gap between sections to allow for expansion or contraction.

6. Secure light guide by twisting tie-wire around the mounting clip and light guide.

7. Wires between light guide segments can be folded behind the light guide and attached with clear zip ties. Zip ties should wrap around outside light guide.

8. To connect two light engines separate wires and identify outer conductors as positive (+) and middle conductors as negative (–). Strip ends back 0.5 in. (13mm).

9. Use twist-on wire connectors to join wires together.

10. Insert wire connectors into weather box. Fill with electrical grade silicone and close box. Weather box can be mounted using #8 (M3) screws.

11. For cut end, manually untwist and separate wires to avoid shorts. Fill cap with electrical grade silicone and push cap on the end to seal. Clean excess silicone.

12. For uncut end, fold wire over Tetra Contour. Fill the end cap with silicone and push cap on the end to secure. Clean excess silicone.
    Joining with Light Guide Connectors, Corners and Bends

13. Linear: At each gap between sections, apply silicone on both sides to secure light guide connector. Snap on a light guide connector.

14. Corner: For all corners (planar, inside, outside) apply silicone on both sides to secure light guide corners. Snap on corner. Follow Steps 8-10 if wires are cut.

15. Bends having an inside radius 1½” or smaller must have electrical grade silicone applied directly to the light engine across the bend.
    DO NOT bend the light engine to an inside radius that is tighter than 3/4 in. (19mm).
    Connect Power Supply
