Dimensions

Planning

For planning the layout, measure the desired length to be lit and divide by the Light Bar Length (L) in the table above to determine the required quantity of light bars. If it is necessary to cut the light bar for a better fit, the cutting resolution is 3 inches (76.2 mm).

Field Cuts

WARNING

Failure to strictly follow these instructions may subject the installer or others to personal injury. Failure to strictly follow these instructions will also void the manufacturer’s warranties and may cause risk of fire, product damage, damage to property, and injury to persons. Please read all warnings contained below and follow all instructions carefully.

1. Gather materials: Seal gasket and cap, conformal coating, electrical grade silicone, sandpaper, cloth.

2. If it is necessary to cut the lightbar for a better fit, the cutting resolution is 3 inches (76.2 mm). Cut the lightbar as necessary to fit the application. Only cut the PCBA from the back to the front. DO NOT cut from the LED side to the back.
   NOTE: Perpendicular cuts ONLY. No angled cuts.

3. Clean debris from extrusion cut end with the sandpaper and avoid sanding the edge of the LED board.

4. Pull out the LED board gently and clean and deburr the cut end with a cloth or other appropriate tool. Be careful not to damage the dielectric, and to ensure no copper from the trace is making contact with the PCB assembly substrate. Finally, shake or blow out any dust and debris from the extrusion.

5. Apply and seal the cut end of the LED board with a brush-on conformal coating such as MG Chemicals 419D, Humiseal 1B73, or Electrolube APL. Allow at least 10 minutes to dry.

6. Push the GELWCAP seal gasket and cap over the cut end of the light bar.

7. Apply electrical grade RTV silicone around the outside circumference of the end cap. Ensure that the silicone completely seals the joint between the end cap and light bar.

WARNING

Field end-cap must create a water tight seal. All debris must be removed to promote a good end-cap bond and to avoid electrical failure. Use of other types of saws and/or use of a dull blade may lead to chipping or cracking of the extrusion or create a cut that cannot be sealed resulting in product failure. Product failures resulting from failure to strictly follow field cut instructions are not covered by any product warranty.

SAFETY WARNING

Failure of field end-cap to maintain a water tight seal may lead to water ingress and product failure. Product failures of this type could result in electrical shock and/or fire and damage to the product and materials which may come in contact with the product.

Attaching Light Bar Sections

Planning first:
For multiple bar installations, see the “Maximum Light Bars in Series Connection” specification in the Maximum Loading chart below. Do not exceed the maximum series length per Leader Cable.

Mounting Options A (standard or slim mounting clips)

1. Secure two mounting clips per light bar to a rigid flat mounting surface using two #10 (M5) self-tapping flathead screws along the intended run of light bar.
2. Press each light bar into its mounting clips and slide it into the adjacent light so that the alignment features in the end caps mate with each other.
   To avoid stress and damage to light bar the entire mounting surface should be flat and the mounting clips be properly aligned. If the alignment features in the end caps do not mate easily, do not force them together.
   TIP: Align light bar on one side of the mounting clips; then rotate the light bar until it snaps into other side of the mounting clips.\

Mounting Option B (standard mounting clips only)

1. Assemble the light bar by pressing two mounting clips onto the light bar. A snapping noise should be heard.
2. Mount the light bar to the desired surface using two #10 (M5) self-tapping flathead screws in each mounting bracket.
3. Mount the next light bar down the row following steps 1 and 2, being sure to align the light using the alignment features on the end cap.

Electrical Connections

1. Mate the male and female connectors of each adjacent light bar while ensuring the connectors are oriented in the same direction. DO NOT attempt to mate upside down or otherwise exert excessive force on the light bar connectors. Be sure that the retaining clip of the connectors are fully engaged and locked together as indicated by a click. Attach jumper cables as needed to work around any obstacles, corners or separations. DO NOT pull on the wires when un-mating the connectors.

2. Install an end cap into the open connector on the last light bar in the series.
   NOTE: If using leader cable with male connector (GE-LC24IN-66M), connect driver and light bar right side female connector, flip the end cap around and install it into into the open male connector on the last light bar in the series.

3. Connect the leader cable to the first light bar in the run closest to the power supply.

To Unmate Connectors

• Pushing the plug latch, grasp the connector at each end and pull apart.
• DO NOT pull on the wires when unmating the connectors.

Connect Power Supply

WARNING

RISK OF ELECTRICAL SHOCK : Turn power OFF before inspection, installation or removal.

Must be used with a Class 2, 24 Volt DC Power Supply. Grounding and bonding must be done in accordance with National Electrical Code (Article 600). Refer to the Power Supply Installation Instructions for more information.

1. Run a wire from the power supply to the leader cable connected to the first light bar in the run.
   NOTE: AC power connection must be contained in an acceptable enclosure .

2. Using twist-on wire connectors, connect the white/red stripe wire (+) from the light bar to the red wire (+) of the power supply. Connect the white wire (-) from the light bar to the black or blue wire (-) of the power supply.

NOTE: All electrical connections should be suitably protected from mechanical damage and the environment. Seal all connections in wet locations with electrical grade RTV silicone.

Retrofit Instructions

1. (Existing Signs Only) Prior to installation, survey the site for information regarding power and accessibility inside and outside the building. Ensure that the branch circuit supplying the existing transformer or ballast will be within the voltage ratings of the new LED power supply, and have a current rating not exceeding 20A, or that permitted by applicable local, state, or country electrical codes (whichever is less).
2. (Existing Signs Only) Remove the existing lighting equipment to be replaced, such as neon tubing or fluorescent tubes; and associated transformers and ballasts. Care should be taken not to break the existing neon or fluorescent tubes. NOTE: Follow all federal and local regulations when disposing of neon tubing, fluorescent tubes, transformers and ballasts.
3. (Existing Signs Only) If removal of the existing lighting equipment eliminates the disconnect switch, as required by applicable local, state, or country electrical codes; a new disconnect switch must be installed.
4. (Existing Signs Only) Repair and seal any unused openings in the electrical enclosure. Openings greater than 12.7mm (1/2-in) diameter require a metal patch secured by screws or rivets and caulked with non-hardening caulk. Smaller openings may be sealed with non-hardening caulk.
5. (Existing Signs Only) A clean and dry mounting surface ensures optimum adhesion if the self-adhesive method of mounting is chosen. Follow the manufacturer’s directions when using a non-oil based solvent, such as rubbing alcohol to clean the surface area where you intend to mount the module. Before installing, ensure the surface is dry.
6. Using the layout guidelines above, determine required number of LED modules required to illuminate the sign.
