FLUORESCENT DIMMER, SINGLE-POLE/3-WAY 8A-277V AC, 60 Hz.
For use with Mark 10®Powerline dimmable ballasts
• Must be installed and used in accordance with all national and local
electrical codes.
• To reduce the risk of overheating and possible damage to this device or
other equipment, do not install to control a receptacle, motor-operated
appliance, or a transformer-supplied appliance.
• Use only with permanently installed 277V AC dimmable fluorescent
fixtures.
• Only one dimmer can be used in a 3-way circuit. The switch on the
other end will turn on at the brightness level selected at the dimmer.
• Do not exceed maximum rating of dimmer as indicated on the strap.
• For new installations, install a test switch before installing the dimmer,
to verify proper lighting circuit operation.
• If a bare copper or green ground connection is not available in the
wallbox, contact a licensed electrician for installation.
• Use only #14 or #12 copper wire rated for at least 75º C with these
devices. DO NOT USE WITH ALUMINUM WIRE.
• It is normal for the dimmer to feel warm to the touch during operation.
• When retrofitting Mark 10® Powerline dimmable ballast into fixtures
that have instant start ballasts, lamp sockets must be replaced with
rapid start sockets to allow proper dimmer operation and prevent
damage to the ballast. Refer to ballast instructions for details.
• Lamps must be burned in at full intensity for 100 hours prior to dimming
for optimal dimming performance.
Remove all inner side sections
DO NOT remove
outer side
sections
Bend back and
forth to remove
side section
• The side sections of the mounting strap may require removal. Use pliers
to carefully bend side sections back and forth until they break off.
• Typically, removal of the side sections in multi-dimmer installations
requires a reduction of the dimmer’s capacity. Refer to Table 1 for
maximum load per dimmer for multi-ganging.

Installation Instructions:
• Determine what type of installation it is.
Single-pole installation — controls light from one
location.
3-way installation — controls light from two locations.
• Turn off power. Remove wallplate.
• Pull out switch — refer to instructions below:
Single-Pole Installation:
Disconnect the existing switch, and connect per
Figure 1 — Single-Pole Wiring Diagram.
• Connect one of the wires of the switch to the
Black screw
• Connect the other wire from the switch to one of
the Yellow screws. NOTE: one of the Yellow screws
is covered by a white label, and is not required for
a single-pole installation.
• Connect the ground wire to the Green screw
3-Way Installation:
• One dimmer can be installed in either switch location, however, you cannot put a dimmer in both locations.
• Select which 3-way switch will be replaced by the dimmer. This will typically be the location that you would normally want to control the dim
level.
• The wire connected to the Common terminal is identified by a marking indicating COM, or the screw color is Black, and is different than
the other two screws. Tag the common wire.
• Disconnect the 3-way switch that will be replaced by the dimmer.
• Connect the dimmer as show in Figure 2 — 3-Way Wiring Diagram.
Connect the tagged common wire to the Black screw on the dimmer.
Connect one of the wires from the switch to one of the two Yellow screws.
Remove the white label, and connect the other wire from the switch to the second Yellow screw.
Connect the Ground wire to the Green screw.
Mount and Test the Dimmer:
• Make sure the word “TOP” is facing up on the dimmer.
• Attach the dimmer to the wallbox with the mounting screws.
• Restore “Power” at circuit breaker or fuse.
• Test if lights turn ON/OFF when pressing the switch. Test dimmer control. Refer to Trouble Shooting section if the device does not function properly.
• Attach wallplate. Test the Dimmer again. Installation is complete.

If the light does not turn ON • Check to see if circuit breaker or fuse(s)
has tripped.
• Check to see if lamp is burned out.
• Check if lamp neutral connection is
wired.
If lights are flickering • Check if lamp has a bad connection.
• Check if wires are not secured firmly
under terminal screws of dimmer
and/or 3-way switch (if installed).
