Isolation Transformer should bee placed on a brick in order to isolate the transformerr from direct contact with metal. The Series Isolation Transformer secondary cable should then be inserted from inside the housing up the condu it elbow. Using the two 40762 retainers supplied with the sign (looks like a cupped washer with a slot), placing one below the secondary cable receptacle (L-823 Style 8, looks like a ball), and one above. The bottom cupped washer sits on the conduit elbbow top inside the threaded conduit coupling and prevents the secondary cable from dropping back down the conduit. The top cupped washer prevents the secondary cable from being pulled out of the grround allowing the sign power cord to disconnect iff the sign is impacted and shears off at its frangible couplings. If a consolidating harness is used orr a secondary cable extension (use electrical tape around connection) is required, use the 25003 (split cllamp with screws and hex nuts) retainer supplied witth the sign. Secure this retainer, flat side down awaay from sign, around the secondary end (L-823 Style 7, looks like a straight tube) that will exit the conduit elbow. The top of the secondary receptacle should be at least ¼ inch below the conduit elbow threaded coupling top surface.

WARNING:

IMPORTANT Check the sign for shipping damage upon arrival and in all cases, check for d amage prior to installation.

h.Lower the sign with the legs and flanges into place. Plug the sign power cable plug into the secondary receptacle inside the conduit elbbow while lowering. Check the sign itself with a loong carpenter’s level to be sure it is level. As an alternate, remove the floor flanges and frangible couplings from the sign, unscrewing the frangible couplings from the floor flanges. Install the floor fla nges onto the sign anchor bolts. Level the floor fllanges for ease of installation of the sign. A long carrpenter’s level can be placed across the top of the floor flanges to be sure they are all in line and level. Do not tighten the anchor nuts tight (only finger-tight) until the frangible couplings are installed back into to floor

flanges. Note: Some verticaal adjustments can be obtained by rotating the floor flanges a turn or two on the frangible coupling.

i.Make sure all flanges are in fulll contact and sit flush on the pad before tightening thhe anchor bolts. Shim and grout as required. Onnce the sign has been leveled, attach the sign tether too the closest anchor bolt and tighten all the a nchor nuts securely. (Note: Anchor hardware is not supplied with the sign.) Anchor hardware should be corrosion resistant. The sign body must not be beent or distorted due to an uneven installation proceddure. Install a bare #14 AWG minimum copper grouund wire to the sign ground stud (stud located on sign bottom extrusion exterior and accepts #4 throough #14 AWG) and the other end to the groundiing rod clamp.

j.The sign is shipped set for a Ferrro-resonant Type L-828 Regulator as illustrated in Table 1. For other Regulator types, set sign power supply circuit card jumper according to Table 2.

k.Return power to series circuit and verify sign illuminates through all Regulator brightness steps.
