Series Loop Power Connections

Make electrical connections to the series loop power using L-823 Primary Connector
a.
Kits.
Attach the primary connectors to the appropriate size L-831 Series Isolation Transformer.
b.
These primary connections (single pin plug or receptacle) should have Heat Shrink Kits
(HSK), applied over their connections to prevent disconnection and water from entering
the cables.
The Series Isolation Transformer should be placed on a brick in order to isolate the
c.
transformer from direct contact with metal, see Figure 11, pg. 36, for details.
The Series Isolation Transformer secondary cable should then be inserted from inside the
d.
housing up the conduit elbow.
Using the retainers, (looks like a cupped washer with a slot), place one below the
e.
secondary cable receptacle (L-823 Style 8, ball shaped), and one above, see Figure 40,
pg. 66. Note, the bottom cupped washer sits on the conduit elbow 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 ground,
allowing the sign power cord to disconnect, if a frangible event occurs. See Figure 12,
pg. 39, for Conduit Elbow Information.
If a secondary cable extension is required, use the retainer, (split clamp with screws and
f.
hex nuts), see Figure 41, pg. 66, for details. Note, use electrical tape around this
connection.
Secure the retainer, flat side down towards the sign, around the secondary end (L-823
g.
Style 7, tube shaped) that will exit the conduit elbow. The top of the secondary receptacle
should be at least 6.4mm [1/4"] below the conduit elbow threaded coupling top surface.
