SloanLED SignBOX 3 Slim Cabinet Lighting
WARNING:
Risk of electrical shock. New installation and LED Retrofit Kit installation
require knowledge of sign electrical systems. If not qualified, do not attempt
installation. Contact a qualified electrician. Follow all national and local
codes. SignBOX 3 Slim is not suitable for submersion or direct exposure to
water for extended periods of time.
For New Installation, proceed with Step 1 below. For Retrofit Installations, begin with Retrofit Instructions.
Components list
- SignBOX 3 Slim assemblies: SloanLED model number 701946-(X)WDLS2
- SloanLED 24 V Class 2 output power supply (refer to “SloanLED Power Supply Guide for Sign Products” for appropriate 24 V power supply models)
- 1 mm² or larger diameter supply wire
- Wire connectors appropriate for wire diameter used
- SignBOX 3 Slim mounting hardware Clips (P/N 402106), Brackets (P/N 402107)(optional), and Couplers (P/N 402108) (as needed).
- M4 (#8) self-drilling/self-tapping tek screws (required to pierce through strap), minimum length 16 mm (5/8″)
- Optional: Electrical grade silicone, nylon zip ties, double stick mounting tape
Tools required
Measuring tape, wire strippers, gloves, cutting tool (sheet metal shears/snips, scissors, utility knife), drill, and screwdriver.
Layout
To populate sign, refer to SignBOX 3 Slim Module density guidelines, test, or contact your SloanLED Representative for recommendations.
New Installation
-
Cutting product: Cut straps and wires between modules to obtain the required length.
Tip: Before cutting wires, refer to the Joining Product section. NOTE:
To minimize the potential for shadows in applications when using frame support tubes, mount modules or frame support tubes such that tubes are centered in between modules and at a depth that will not directly interfere with the beam angle of LEDs.
Joining Product -
When cutting wires between modules, leaving one side longer will aid in joining the product where needed. If, however, wires are not long enough for connections, use either jumper wires or remove a module to maximize wire length.
-
Use SignBOX 3 Clips (P/N 402106) and SignBOX 3 Couplers (P/N 402108) to join shorter pieces of product to required length. Insert straps from both sides of modules into clips (track features facing the same direction). Slide onto couplers, and secure to them with M4 (#8) tek screws. Connect wires.
Tip: Use pliers to help hold parts during assembly.
SignBOX 3 Coupler dimensions:
54 mm x 19 mm x 2.5 mm (2.125 in x .75 in x .10 in)
Structural Support Guidelines for SignBOX 3 Slim
Vertical mounting: space supports at even intervals, but no further apart than
2.4 m (8 ft). Horizontal mounting: space supports at even intervals, but no
further apart than 1.2 m (4 ft).
Mounting Product
-
Mounting modules with SignBOX 3 Clips (P/N 402106) directly to cabinet structure:
Insert straps from both sides of the module into clips (bracket tracks facing away from mounting surface) and secure to cabinet structure using M4 (#8) tek screws. Repeat on the opposite end making sure the product is taut. -
Mounting modules with SignBOX 3 Clips (P/N 402106) using SignBOX 3 Brackets (P/N 402107):
Install brackets 305 mm (12 in) center-to-center along the returns of the cabinet. Insert straps from both sides of the module into clips (bracket tracks facing the same direction). Slide onto the bracket, and secure with M4 (#8) the screws. Repeat on the opposite end making sure the product is taut.
Connecting Product to Power Supply
They are using electrical connectors with appropriate safety agency markings, daisy chain product as required, and connecting to the power supply as shown above. CAUTION! Have a licensed electrician connect the primary. Modules may be connected in series* or parallel. The end wires of SignBOX 3 Slim should be capped and not tied back to the power supply.
SloanLED recommends connecting no more than 36 modules in series for optimal performance.
WARNING check polarity:
All connections must be RED-TO-WHITE WITH RED STRIPE (+) and BLACK-TO-WHITE
(-). Reverse polarity connections may damage LEDs and will void the product
warranty.
Retrofit Instructions for Existing Signs
WARNING:
Risk of fire or electric shock. Install this kit only in host signs that have
been identified in the installation instructions, and where the input rating
of the retrofit kit does not exceed the input rating of the sign. Installation
of this LED retrofit kit may involve drilling or punching holes into the
structure of the sign. Check for enclosed wiring and components to avoid
damage to wiring and electrical parts.
CAUTION:
Turn off the power to sign before inspecting or removing the existing light
source. Power must remain off while installing LED products.
-
Identify the sign to be retrofitted and ensure the branch circuit supplying the existing sign are within the voltage range for the LED power supply.
Refer to the components list (page 1) and “24 VDC Power Supply Capacity Chart” (page 4). -
Remove existing lighting equipment intended to be replaced, such as neon or fluorescent, and all power supplies, transformers, or ballasts. Remove existing neon and all standoffs to leave an empty sign cabinet. NOTE: All materials removed must be disposed of in accordance with applicable local or national regulations.
-
If required by local or national regulations, install a new disconnect switch.
-
Determine suitability and structural integrity of existing sign after removal of existing lighting equipment. If retrofit does not require the making
of any new holes, do not make or alter any open holes in an enclosure of wiring or electrical components during kit installation. If existing holes are present in a wet or outdoor location sign, repair and seal any unused openings in the electrical enclosure.
Openings greater than 12.7 mm (0.5″) in diameter require a metal patch secured by screws or rivets and caulked with non-hardening caulk. Smaller openings may be sealed with non-hardening caulk. -
Clean the inside of the sign using a non-oil-based cleaner. Follow all manufacturer’s instructions and ensure the inside of the sign is dry before proceeding with the installation.
-
To populate the sign, refer to SignBOX 3 Slim density guidelines as well as the power supply capacity chart (page 4) to determine an appropriate number of modules and power supplies. A list of acceptable power supply models is shown in the supplemental “SloanLED Power Supply Guide for Sign Products”.
-
Follow all instructions on pages 1 and 2 under “New Installation” to properly install LED modules.
-
Connect modules to power supply output as shown on page 3 under “New Installation”.
-
Connect power supply input as outlined in the power supply installation guide in accordance with local or national regulations. Refer to the power supply install guide included with the power supply for details.
-
If required, install a disconnect switch in accordance with local or national regulations by qualified personnel.

Extension of Power Supply Leads
If a longer lead wire from the power supply to LED modules is needed, an
extension can be used. The extension should be kept as short as possible,
i.e., under 4.6 m for 1 mm² PLTC (15 ft for 18 AWG UL Listed PLTC) or under
15.2 m for 2.5 mm² PLTC (50 ft for 14 AWG UL Listed PLTC).
Troubleshooting
Entire box/cabinet or product does not light after complete
installation.| Check connection from power supply lead to first module.
Make sure polarity of connections made at power supply lead and any jumper
wire is correct. Power supply outputs should be connected RED-TO-WHITE WITH
RED STRIPE and BLACK-TO-WHITE.
---|---
Still does not light.| Check output voltage of power supply using a
voltmeter. The output voltage should be DC 24.0 V ± 0.5 V. If there is no
output voltage, have a licensed electrician check input voltage. Make sure
power supply is connected correctly and getting primary power. If power supply
is connected properly and getting primary power and there is still no output
voltage, try a different power supply.
Still does not light.| If power supply is getting primary power and
modules don’t light, there may be a short in the secondary wiring. Check all
connections and cap all loose wires.
The beginning of a strip lights, but entire strip does not light or lights
intermittently.| The primary cause of a portion of a SignBOX 3 Slim leg not
lighting or lighting intermittently is a bad connection or reverse polarity
connection between modules that light and modules that don’t light. Check this
connection.
One module does not light, but all others in the product light.| SignBOX
3 Slim is designed so if one module fails, it will not cause the entire
box/cabinet or strip to go out. If one module does not light, but all others
in the product do, replace this module with a new one.
