Single Pole (One location) or 3-Way (Multi-location) 

Magnetic Low-Voltage Dimmer

Cat. No. VZMØ6-1L, 600VA (Lighted) 

120VAC, 60Hz

INSTALLATION INSTRUCTIONS

DI-000-VZM06-02C

If installing Dimmer in a single device application, proceed with the 

INSTALLINg yOUR DIMMeR

 section. If installing Dimmer in a 

multi-device application, proceed as follows:

MULTI-DeVICe AppLICATION

In multi-dimmer installations, the reduction of the dimmer’s capacity 

is required. Refer to the chart for maximum load per dimmer.

MAXIMUM BULB WATTAge

Low-voltage dimmers are rated in Volt-Amps (VA). The maximum 

bulb wattage is determined by the efficiency of the transformer in the 

low-voltage lighting system. Transformer efficiencies will vary from 

different manufacturers; consider 75% efficient as average. Use the 

chart to determine maximum bulb wattage for typical transformer 

efficiency ratings.

NOTe: 

Use check boxes          when Steps are completed.

WARNINg:

 

TO AVOID fIRe, ShOCk, OR DeATh; 

TURN Off pOWeR

 at circuit breaker or fuse and test 

that power is off before wiring!

 If the wiring in the wall box does not resemble any 

of these configurations, consult a qualified electrician.

WIRINg DIMMeR:

Connect wires per WIRINg DIAgRAM as follows:

WARNINg:

 

CONNECT A MAGNETIC LOW-VOLTAGE DIMMER

ONLY TO THE PRIMARY (HIGH-VOLTAGE) SIDE OF A MAGNETIC
LOW-VOLTAGE TRANSFORMER.

  Green or bare copper wire in wall box to Green terminal screw.

• 

Line Hot wall box wire to terminal screw marked “BK”.

• 

Load wall box wire to terminal screw marked “RD”.

•   

Dimmer terminal screw marked “YL/RD” should have Red 

insulation label affixed. 

   NOTe: 

If insulating label is not affixed to terminal screw marked 

“YL/RD”, use electrical tape to cover.

•  Make sure that the ends of the wires from the wall box are 

 

  straight (cut if necessary)

.

•  Remove insulation from each wire in the wall box as shown.
• 

for Single-pole Application, go to Step 4a.

• 

for 3-Way Coordinating Remote (no LeDs) Application, go  

  to Step 4b.

• 

for 3-Way Matching Remote (with LeDs) Application, go to  

  Step 4c.

WARNINgS AND CAUTIONS:

•  To be installed and/or used in accordance with appropriate electrical codes and regulations.
•  If you are unsure about any part of these instructions, consult a qualified electrician.
•  To avoid overheating and possible damage to this device and other equipment, do not install to control a receptacle, fluorescent lighting, a motor- or a transformer- 

  operated appliance.
•  Use with magnetic low-voltage transformers, incandescent, or 120V halogen fixtures only. Use a Leviton electronic low-voltage dimmer to control electronic (solid  

  state) low-voltage transformers.
•  When magnetic low-voltage circuits are operated at a dim level, with all lamps inoperative, excess current may flow through the transformer. To avoid possible 

transformer failure due to overcurrent, use a transformer that incorporates thermal protection or a fuse at the primary windings.

•  Vizia™ dimmers are not compatible with standard 3-way or 4-way switches. They must be used with compatible Vizia™ remotes for multi-location dimming.

WARNINgS AND CAUTIONS:

•  Use only one (1) Vizia™ dimmer in a multi-location circuit with up to 9 coordinating remotes without LEDs or up to 4 matching remotes with LEDs. The remote(s) will turn 

the light on at the brightness level selected at the dimmer.

•  Total minimum load must exceed 40W.
•  Dimmer may feel warm to the touch during normal operation.
•  Recommended minimum wall box depth is 2-1/2”.
•  Maximum wire length from dimmer to all installed remotes cannot exceed 300 ft.
•  Disconnect power at circuit breaker or fuse when servicing, installing or removing fixture.
•  Use this device only with copper or copper clad wire. With aluminum wire use only devices marked CO/ALR or CU/AL.

IMpORTANT:

 For 3-Way applications, note that one of the screw 

terminals from the old switch being removed will usually be a 

different color (Black) or labeled Common. Tag that wire with 

electrical tape and identify as the common (Line or Load) in both the 

dimmer wall box and remote wall box.
