Check connection from power supply lead to ﬁrst module. Make sure polarity of connections

made at the power supply lead and any jumper wire is correct. Power supply outputs should

be connected red-to-red and white-to-white.

Check output voltage of power supply using a voltmeter. The output voltage should be

24.0VDC ± 0.5VDC. 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.

If power supply is getting primary power and the modules do not light, there may be a short

in the secondary wiring. Check all connections and cap all loose wires.

The primary cause of a portion of a S-LED leg not lighting or lighting intermittently is a bad

connection or reverse polarity connection between the modules that light and the modules

that don't light. Check this connection.

S-LED is designed so if one module fails, it will not cause the entire sign or leg to go out. If one

module does not light, but all others in the leg do, replace this module with a new one.

Check each run has no more than maximum number of modules. Also ensure that type of the

extension wire from SMPS to the ﬁrst module is correct. If wires are not thick enough to

transmit current from SMPS, this will cause voltage drop and will dim the modules at the end.

Channel depth is too low, or center distance between modules is too far. Refer to 'LAYOUT

DENSITY GUIDELINES' for more information.

Covering acrylic is not intended for LED illumination. Use light diﬀusing acrylic sheets which

are specially made for LED light source.
