SAFETY GUIDELINES
Low voltage installation and maintenance is safe and presents
no risk for electric shock injury. However, there are regulations
that may apply and that should be followed by installers. The
following safety points may or may not be included in these
regulations - the installer is responsible for ensuring a compliant
installation.
◗ WARNING- RISK OF SHOCK. Install power unit at least 5 feet
(1.5m) from pool or spa and at least 10 feet (3.05m) from a
fountain.
◗ WARNING- install power unit in or on non-combustible materials
only.
◗ Power supply must be connected (using supplied power cord) to
GFCI-protected receptacle with an In-use cover.
◗ All VOLT
®
power supplies are indoor and outdoor rated, but we
recommend that the transformer be mounted outdoors. If mount-
ing indoors, check for local electrical codes that may apply.
◗ Power supply must be mounted in a vertical orientation with the
bottom plate at least 1 foot above the ground.
◗ In hot climates, avoid mounting in direct sunlight. Power unit will
get hot regardless of climate. This is normal for operation.

Open the shipping carton and carefully remove the
transformer, accessories, and hardware. Note that
transformer mounting hardware is not included. Inspect
contents for any damage that may have occured during
shipping.

Your general capacity should have been determined prior to
purchasing your transformer. Circuit loads should not exceed 80%
of capacity. As a general rule, total light xture wattage should
not exceed 80% of transformer capacity. To determine your
total wattage, simply add up the wattage of all xture lamps.
This number should be 20% less than the transformer’s wattage
capacity. If you need help with this, give customer service a call
at 813-978-3700. If you are over capacity, your installation may
require a secondary or larger transformer.

Quick Start Guide Steps
1. Read the safety instructions and unpack your transformer.
2. Mount your transformer.
3. Run wires from transformer location to xtures or hubs.
4. Attach all wires to transformer terminals. For each paired wire, attach one
side to a common terminal and the other side to the voltage terminal.
5. Check that all of your connections are secure.
6. Plug in your transformer.
7. Flip the ON/OFF breaker switch upward to power on your transformer.
8. Check that your transformer pilot light and timer pilot light are both on.
9. Turn your timer clockwise to manual “On” mode.
10. Check that all of your xtures are on and functioning properly.
11. Measure the voltage at xtures or hubs.
12. If needed, use another voltage terminal (some transformers only have
one).
13. Set your timer to the desired function.
14. Close the transformer door using the locking mehanism to seal the unit
from weather and debris.
15. At Dusk, make any last minute adjustments to your xtures. Bury the
wire only after you have made these adjustments.

The transformer can be mounted directly to the wall or on the
optional pedestal. If mounting directly to the wall, be sure
to use wall anchors to insure your transformer is secure. With
either method, be sure that you are within 5 feet of a GCFI
protected outlet with an In-Use cover.

With your plans or layout in hand, run your wires from your
transformer to your hub and/or xture locations. Leave
extra slack as you may want to adjust xtures at night to
achieve your desired effect.

Attach all of your wires to the transformer. Using the
common and voltage terminals split each wire and t one
side into the common and one side into your desired voltage
terminal (some transformers will only have one terminal).
1. Fish the wire through wire slots and into the transformer.
2. Flip up the easy connect lever which will allow wire entry.
3. Bare the lead ends of your wires to allow metal to metal
contact within the connector.
4. Slide one side of the wire into the common terminal and one
side into the voltage terminal, then clamp both levers down onto
the wires. Check for a strong connection by rmly pulling on the
wire.

Firmly pull each individual wire to ensure that they are all
completely secure. If you have an issue with a wire that is
not secure, try snipping the end and baring less wire at the
end before remaking your connection.
Quick Start Step 5
Plug in your transformer at a GFCI protected outlet with
an In-Use cover.
Quick Start Step 6
Flip the transformer’s internal breaker upward to the on
position to power on the unit.
Quick Start Step 7

Page 11
Check that both pilot lights are on inside your transformer
power unit. The main pilot light for your transformer is
green and right above the internal breaker. If it is not on,
your transformer is not receiving power. Check that the
breaker for your GFCI outlet is on. For any line voltage
issues, contact a licensed electrician.
The timer’s pilot light is blue and towards the top of the
timer. Be sure that the timer pilot light is also on to ensure
proper timer function.
Quick Start Step 8
Turn your timer clockwise to the manual “ON” setting by
aligning the word “ON” with the orange triangle on the left.

Using a volt meter, measure the voltage at your xtures by
removing the lamp and using the probes in the bulb receptacle.
Be sure that all other lamps are installed at the time of testing.
For integrated xtures, test voltage at the closest connection
point to the lighting xture. A good range is typically between
10.8 -15 volts for LED lighting xtures.
Quick Start Step 11
www.voltlighting.com
Go around and check that all of your xtures are on and
functioning properly. Flickering or xtures that aren’t powered
on could present a connection problem at the xture or lamp. If
a failed lamp is suspected, try replacing it with another that is
working in a different location. This will help you to troubleshoot
where the problem is.
