LED CHANNEL LETTER INSTALLATION INSTRUCTIONS <br />Flush Mount Channel Letter Installation Instructions - LED Channet/Let:ers <br />Ihis sign is intended to be installed in accordance with the requirements of Article 600 of the <br />National Electrical Code and,ror other applicable local codes. This includes proper grounding and <br />bonding of the sign. <br />1. Refer to the drawing included with the letter set that depicts the arrange ment of the <br />subassembiies. <br />2. Unroll paper pattern, and tape to 5Ubstrate. Level and canter pattern on wall. Drill holes for <br />secondary low voltage whips and mounting holes, and then remove pattern. Mount letters on the <br />wall using the drawing as a guide. If letter set does not have rivet nuts, remove faces push <br />secondary low voltage whips through substrate, mount letters onto substrate. and then replace <br />faces. If the letterset does hme livet nuts. install threaded rod into Tivet nuts then push secondaly <br />low'voltage whips (run in metal conduit) through substrate and secure with hardware from the back <br />side of substrate <br />3. Refer to wiring diagram below @gure 1) and the transformer breakdown diagram (provided with <br />letter set) to splice tile secondary conduciors. Each secondafy circuit has a dedicated <br />transformer and is color coded on the transformer breakdown sheet. Connect all of the pwitive <br />leads (red or white insulation) from each letter in the secondary circuit together in parallel using UL <br />approved wire cut: or c,imp connectors (crimped with manufacturer's specified crimping tool) <br />Next connect all of the negative leads (black insulation) from each letter the secondary circuit <br />together in parallel using UL approved wire nuts or crimp connectors (crimped with manufacturer's <br />specmed crimping tool). Finally, connect all of the ground leads (bare wife with no insulation) from <br />each letter the secondary circuit together in parallel using UL approved wire nuts oricrimp <br />connectors (crimped with manufacturer's specified crimping tool), Repeat this process for each <br />secondary circuit. <br />4. If a Sloan damp location rated transforner is supplied, no transformer box is required (skip to <br />step 6). If any other liansformer is supplied, a transformer box will also be supplied. In this case, <br />mount the transformer boxes; OPEN SIDE UP, as close as possible to the centet of the circuit <br />that will be powering. It should:be mounted at the same height as.the letter set to minimize whip <br />lengths. Next, install the transformer in the box as specified per the transformer box <br />manufacturer's instructions included. <br />5. Route the three secondary clicuitileads (positwe. negative and ground) inside the transformer <br />box. <br />6. Connecl the three secondary circuil leads (positive. negative and ground} to the trans former <br />and/or transformer box as specified per the transformer and/or transformer box manufacturer's <br />instructions included. <br />7. Connect the primary electrical supply to the transfofmer per the transformer manufacturer's <br />instructions included. <br />8. Repeat the steps above for each transformer circuit. <br />9. At leastone On/off switch, rated for the application, must be installed on the primary "hot" lead <br />within the line of sight of the transformers. <br />10. Signs cannot be connected to a branch circuit exceeding 30 amperes <br />Secondary Secondary <br />Circuit#1 Circuit #2 <br />1.2-1 -let <br />I :u•or==--el - I. .... 9 <br />21 510 St.8 her·,i Street <br />Carloga hrk, CA 91304 <br />T 800.525.5519 <br />F 813 787.G415 <br />wwv;.vi:iblegraphics.corn <br />F< <br />1. 1:1 6·55:E+44t * -tki Bpi:Hr+I.i:ftiO< 51.34-f.; 0..·3 <br />.
