FIXTURE RETROFIT INSTRUCTIONS
WARNING - To avoid shock or re hazard, turn o power to the xture at
the appropriate breaker or fuse panel.
STEP 1: Verify the voltage rang of the MK2m product (120-277Vac) matches the
voltage of the xture circuit.
STEP 2: Remove old uorescent lamps and remove the ballast cover.
STEP 3: Cut all wires aached to the ballast(s) as close to the ballast(s) as possible.
Leave the ballast(s) in place.
Note: TOGGLED MK2m lamps are powered from a single-end (designated with the
product label or markings) and require the use of non-shunted lampholders.
If the lampholders are shunted, replace them with the non-shunted lampholders
supplied with the lamp(s). See "Shunted Lampholder Replacement" below.
STEP 4: Connect one wire from each lampholder at one end of the xture to line
(black) and separately connect the other wire to neutral (white). At the opposite end
of the xture, cut all wires from the lampholders.
Note: Ensure the xture is and remains grounded aer the retrot process.
STEP 5: Reinstall any removed wiring covers and ballast covers.
STEP 6: Ax the included xture-modicaon label to the newly retroed xture. To indi-
cate which end is powered, place the label on the ballast cover nearest the powered end.
STEP 7: Install the new TOGGLED MK2m lamp(s). Be sure to install the lamp in the
proper orientaon (the end with the product labels/markings should be connected
to the AC wired lampholders).
SHUNTED LAMPHOLDER REPLACEMENT
STEP 1: Remove any brackets or covers holding
the shunted lampholders in place.
STEP 2: Cut any wires aached to the shunted
lampholders. Be careful to cut the wires as close to
the shunted lampholders as possible. You will need
to reuse this wire.
STEP 3: Strip wires according to the strip gauge on the
new lampholders. If a gauge is not available, strip wires
3/8" [9.5mm].
STEP 4: Insert 1 wire on each side of each lampholder
as indicated below.
STEP 5: Reinstall the lampholders and any removed
covers or brackets.
