Risk of fire or electric shock. Installation of this Retrofit Kit requires
knowledge of electrical systems. If you are not qualified , do not attempt
installation, and contact a qualified electrician.
Risk of fire or electric shock. Install this kit only in the luminaires that
have the construction features and dimensions shown in the photographs and/or
drawings and where the input rating of the retrofit kit does not exceed the
input rating of the luminaire.
Do not make or alter any open holes in an enclosure of wiring or electrical
components during kit installation.
To prevent damage to wiring, do not expose wires to the edges of sheet metal
or other sharp objects.
To avoid potential fire or shock hazard, do not use this retofit kit in
luminaires employing shunted bi-pin lampholders. Note: Shunted lamp holders
are found only in fluorescent luminaires with Instant-Start ballasts. Instant-
Start Ballasts can be identified by the words “Instant Start” or “I.S.” marked
on ballast. This designation may be in the form of a statement pertaining to
the ballast itself, or may be combined with the marking for the lamps with
which the ballast is intended to be used, for example F40T12/IS. For more
information, contact the LED luminaire retrofit kit manufacturer.
Installers should not disconnect existing wires from lampholder terminals to
make new connections at lampholder terminals. Instead installers should cut
existing lampholder leads away from the ballast and make new electrical
connections to lampholder lead wires by employing applicable connectors.
WARNING- Risk of fire or electric shock. Luminaire wiring and electrical
parts may be damaged when drilling for installation of LED retrofit kit. Check
for enclosed wiring and components.
