INSTRUCTIONS: Low Voltage Mono Rail Kit

Models: LM-SK-150E & LM-SK-250E

Caution:

Read all instructions.

Turn off power at main switch before installing or modifying the system.

Do not install the system:

-Within six inches of any curtain or combustible materials

-Less than 5 feet above a floor

-In a damp or wet location

-Concealed, or extended through building walls.

After first 1/2 hour of operation, switch off and check all connections for excessive heat.

Loose connections must be tightened to prevent overheating which can damage the system and

pose a potential fire hazard. Do not over tighten.

Intended for installation by a qualified electrician.

Installation should be in accordance with NEC and local codes. Use minimum AWG #10 wire for

secondary wiring.

Overview:

Power to low volt mono rail is supplied by a 12 volt 150 watt electronic transformer (model LM-

SK-150E), or by a 250 watt transformer ( model LM-SK-250E). The transformer is generally

compatible for use with standard incandescent dimmers.

Choices of Mono rail fixtures include rail mounted heads, quick connect fixtures, and quick

connect pendants.

This kit contains the components for mounting to a flat surface such as a dry wall ceiling or wall.

Accessories may be purchased for drop ceiling, or sloped ceiling applications.

Mono rail is composed of two copper conductors separated by a plastic insulator. It is flexible and

bendable. Rail is supplied in 4 ft lengths and may be field cut.

The junction box will support the entire weight of the transformer, make sure it is adequately braced and supported. Extension wires are supplied to connect junction box wires to the transformer input wires. Connect white neutral wire to white wire, and black hot wire to black wire with wire nuts.

Monorail mounting: Rail can be installed on a flat surface, a sloped ceiling, or a suspended ceiling. 1. 2. 3. 4. Use two standoffs for 4ft rail, and three for an 8ft section. Use additional standoffs to support tightly curved sections. If bending rail, do this at floor level, then raise to ceiling and mark the location of standoff supports. If rail cannot be raised, use a plumb line to mark location of stand offs on the ceiling.

Field Cutting a Standoff: 1. Remove the small setscrew located on the upper fitting and pull the rod free (use a 1/16” allen wrench). 2. Use a tube cutter for the cleanest cut. If using a hacksaw be sure to brush away any metal filings. 3. Cut to size and refit. 4. The procedure for standoffs on the power feed canopy is the same. T-Bar Ceilings: Note: Rail stand offs are required to be mounted to structural members. Do not mount only to acoustical panels. 1.

Field Cutting Rail: 1. Rail may cut to length in field. 2. Use fine-toothed hacksaw or heavy-duty bolt cutter. 3. Thoroughly clear away all cutting debris. 4. Inspect end to insure the insulator has not been damaged and there are no sharp edges. 5. Re-install track end cap. Installing Fixtures: Note: Fixtures attach to the rail with a two-piece adapter. It is important that the setscrews of the adapter all face the same way. This reduces the possibility of an electrical short. 1.
