Check product label for specific electrical
specifications related to installation.
Improper installation will void warranty.
Wiring and Voltage Selection
12 AWG landscape wire is generally recommended. For optimal
results, lights should be distributed evenly along the cable run, with
higher power lights being closest to the transformer. Higher voltage
terminals can be used with longer runs to make up for
slight voltage drops. The below equation and table can be used to
select the appropriate wire gauge for an application.
Note: When connecting wiring to transformer, do not loosen top
terminals on 75 W models as they are for internal wiring only.

Transformer Mounting
With all gray tabs set at the inner position, the timer will not affect
function and the connected lights will stay on unless power is
switched off.
1. To set up the timer, begin by rotating the timer dial until the arrow
on the right points to the current time
2. (this system uses a 24-hour clock).
3. Next, slide dark gray tabs outward at times when system
should be powered off.
Note: The system can be manually turned off using the
main power switch as well.

Safety and Notes
• Product should be installed and serviced in accordance with applicable
national, state, and local building and electrical codes.
• Risk of fire or electrical shock. Install transformer at least 10 ft
(3.05 m) from pools, spas, or fountains.
• Outdoor, above ground installation only. For use with low voltage
landscape lighting only.
• Transformer has a built-in circuit breaker which can be reset by removing and
then restoring power.
• Transformer must be connected to GFCI-protected receptacle marked suitable
for wet locations. Receptacle must be protected by a weatherproof cover.
• Do not submerge the transformer or use it to power submersible lights or lights
mounted in or near pools, spas, or fountains.
• If cleaning is necessary, use a damp cloth to wipe down case. Do not spray
transformer with pressurized water or steam.
• Do not use with dimmer or extension cord or wire in parallel with other
transformers.
• Do not exceed 70% of the maximum wattage of the transformer when
connecting lights.
• Transformer must be mounted in a vertical orientation, with the bottom at least 1
ft from the ground.
• Ensure all mounts are securely attached and will support the transformer's
weight. Failure to properly support transformer may result in damage or injury,
for which the manufacturer does not assume responsibility.
• Do not attempt to disassemble or modify transformer.
• Ensure wiring to lights is correct gauge for the run and total power of the
intended circuit and is intended for use with outdoor landscape applications.

Transformer Sizing
Total load (watts or volt-amperes) of all fixtures connected to one
transformer must not exceed 70% of the W or VA capacity of the
transformer. Use the below equation to calculate the most
suitable transformer.
total fixture load (W or VA) ÷ 0.7 = minimum transformer capacity
Transformer Mounting
Mount transformer to solid surface using stainless hardware capable
of supporting the weight of the transformer. Hardware is not included.
Once screw(s) are properly mounted, slide transformer over screw
heads and tighten screw(s) to lock in place once the
transformer is level.
System Check
After installing entire system, apply supply power. After five minutes
of operation, remove supply power. Check all low voltage electrical
connections, which should be cool to the touch. If any connection is
warm to the touch, check and re-tighten the connection and repeat
the process until all connection problems are resolved.
