Installation Guide

Standard 12-Volt DC LED Power Supply
Model # ZF120A-1200830, ZF120A-1202000, ZF120A-1205000
Highly effi cient, stabilized, constant voltage DC power for LED lighting
INSTALLATION GUIDELINES
Power must be disconnected at all times during installation.
Observe polarity of the 12-volt DC output. Failure to observe
polarity could damage LED lighting.
Total wattage of all LED fi xtures used must not exceed the
maximum watt rating of the power supply.
These electronic LED power supplies are not compatible with
standard 120-volt AC dimmer switches. Use only Armacost
Lighting low voltage 12-volt DC LED dimmers for brightness
control of lighting.
■
Full safety shut off protection in case of lighting overload, open
circuit, short circuit, over-temperature or other fault. Unit will
automatically restart after the fault has been corrected.
■
For dry location use only. Allow for ventilation. Do not install
in cabinet smaller than 12 in. W x 12 in. H x 12 in. D.
■
Use only insulated staples or plastic ties to secure cords
and wires.
■
Route and secure wires so they will not be pinched or damaged.
■
All wiring must be in accordance with national and local
electrical codes, low voltage Class 2 circuit. For wire runs
inside of walls, use properly certifi ed CL2 or better cabling
and appropriate mounting hardware. If you are unclear as
to how to install and wire this product, contact a qualifi ed
electrician. Failure to install this device properly may result
in electrical shock or fi re.
■
Do not install Class 2 low voltage wiring in the same runs
as AC main power. If AC and low voltage wires cross, keep
them at 90-degree angles.
Comes prewired with AC
cord and plug for use with
existing outlets. When
end caps are removed,
this power supply can
also be direct wire
installed through
on-board terminal
blocks. Unit is
Class II; a ground
is not required. Use minimum 18-14 AWG rated cable to tie
in with line voltage.

Understanding Voltage Drop
Voltage drop is a natural occurrence in low voltage lighting systems.
It is the gradual decrease in voltage that occurs along the length of
the 12-volt power feed wires to the lighting, and varies depending
on the type and size of installation. It is a function of wire length,
wire thickness, and the energy, or total watts, used by the lighting.
Voltage drop only becomes undesirable if you notice the
brightness in one area of your lighting is objectionably different
than in another area. With LED tape lighting, voltage drop also
occurs along longer length strips. As a practical approach, test
your lighting prior to fi nal installation.
If voltage drop appears to be a concern, shorten your 12-volt
power feed wires or switch to a heavier gauge wire (lower AWG
number). You can also shorten the length of an LED tape light
installation, or consider using an additional power supply to
create a second, separate installation.
LED light color and brightness are best when the 12-volt
power feed wires from the power supply to the LED lighting is
delivering as close to 12 volts as possible.
Excessive voltage drop = reduced brightness and color accuracy
Shorter and/or thicker wires = higher brightness and color consistency
Longer LED tape = an increase in voltage drop
