Dimmer Installation Instructions 030-1002
Please Leave for Occupant
Electronic Low-Voltage Dimmer
VTELV-600M: 120 V~ 60 Hz 600 W
Companion Dimmer
VT-AD: 120 V~ 60 Hz 8.3 A
This Dimmer is used to control the primary side of electronic
transformer-supplied low-voltage lighting, incandescent lamps, or a
combination of the two.
Important Notes
Please read before installing.
1. To avoid overheating and possible damage to other equipment, do not
use to control receptacles, fluorescent lighting fixtures, motor-operated
or transformer-supplied appliances.
2. Some fixture manufacturers do not recommend dimming their solid-state
transformers. To determine if a fixture can be dimmed, consult the fixture
manufacturer.
3. Install in accordance with all national and local electrical codes.
4. The Electronic Low-Voltage Dimmer (Main Dimmer) requires a neutral wire for
operation. If no neutral wire is present, contact a licensed electrician for
installation.
5. A neutral wire is not necessary for the installation of the Companion Dimmer
(VT-AD).
6. The Main Dimmer must be wired on the load-side of a multi-location circuit.
7. When "no grounding means" exists within the wallbox, then the NEC
Article 404.9 allows a switch without a grounding connection to be installed as
a replacement, as long as a plastic, noncombustible wallplate is used. For this
type of installation, twist a wire connector onto the green ground wire of the
Dimmer or remove the green ground wire.
8. The Main Dimmer is not compatible with standard 3-way switches. Use only
with a Companion Dimmer.
9. Companion Dimmers cannot be used individually but must be used in
conjunction with a Main Dimmer in a 3-way/4-way application.
10. In any 3-way/4-way circuit, use only one Main Dimmer with up to four
Companion Dimmers.
11. Do not use where total load is greater than the rating indicated in the Derating
Chart below.
12. Operate between 32 °F (0 °C) and 104 °F (40 °C).
13. The Main Dimmer may feel warm to the touch during normal operation.
14. Recommended wallbox depth is 2.5 in (64 mm) minimum.
15. Maximum total wire length between all Vierti devices is 250 ft (76 m).
®
16. For new installations, install a test switch before installing the Dimmer or test
with a breaker.
17. Do not paint the Main Dimmer or Companion Dimmer.
Multigang Installation
Vierti wallplates are available in one to six gang versions. When combining controls
in a wallbox, derating of the Main Dimmer is required; see the Derating Chart
below.
Note: Companion Dimmers do not need to be derated.

Preparing for Installation
1 1
Turn the Power OFF
• Turn the power OFF at the circuit breaker (or remove the fuse).
WARNING: Verify that power is
OFF before proceeding. Failure
to turn power OFF could cause
death or serious injury.

Remove Wallplate, Switch, and Wires from Switch
• Remove the wallplate and switch mounting screws.
• Carefully remove the switch from the wall.
• Disconnect wires from switch Only.
3 3 Check the Wiring
This Dimmer requires special wiring to control electronic low-voltage

fixtures.
Before starting, make sure that the wires shown below are available in your
2008,
®
wallbox. If these wires are not available in your wallbox, contact a licensed
electrician to have them installed.
All wiring must comply with national and local electrical codes.

Check new installations for short or open circuits BEFORE installing the
3 3 b b
Dimmer.
Proceed as follows:
1. Make certain that the power has been turned OFF at the circuit
breaker or that the fuse has been removed.
2. Connect a standard switch as shown in the Test Switch Wiring Diagram
below.
3. Turn the power ON at the circuit breaker box or replace the fuse.
4. Turn the switch ON.
If lights do not come on, there is a break in the wiring. If the breaker
trips, there is a short in the wiring. If necessary, turn the power OFF at
the circuit breaker box or remove the fuse, correct any wiring problems,
and recheck the circuit.
5. After the problem has been corrected, remove the test switch before
proceeding with the installation.
6. If a test switch is not available, use wire connectors to make
appropriate connections to turn the lights on.

Prepare the Dimmer for Installation
• The Dimmer has a pre-installed Vierti wallplate. Remove the wallplate
before proceeding with the installation.
• The Dimmer has a pre-installed front module containing LEDs. Before
proceeding with the installation, grab the module and pull it straight
out. Removing the Front Module will expose the mounting holes.
Grasp the wallplate at top and pull forward to remove.
All ground wires must be
properly connected to
green wire on Dimmers.
Grasp the front module on each side and pull to remove.

Wiring the Main Dimmer (Only the Main Dimmer is used in this installation.)
1. Connect the green ground wire to the bare or green ground wire in the wallbox.
2. Black screw: Connect the live supply wire (120 V~), disconnected from the
removed switch, to this screw.
3. Brass screw: Connect the other wire (disconnected from the removed switch -
Dimmed Live) going to the black wire of the electronic low-voltage transformer,
to this screw.
