National Electrical Code as well as local codes must be adhered to in the
installation of these models. All electrical wiring must be routed through
approved conduit and fittings as specified.
WARNING
Property damage, serious injury, or death could occur if
independent conductors are terminated together. NFPA 72
requires that the wires be terminated independently to provide
electrical supervision of the connection.
Property damage, serious injury, or death could occur if the
housing is not closed properly.
