Transformer size should be determined by the number of fixtures on each circuit (include any possible planned additions). 1996 NEC allows for
25 Amp max per circuit for systems 30VA or under. On 12V systems, the max is 300W per circuit. On 24V systems, the max is 600W per circuit. Con-Tech transformers are sized to carry the full rated load. No downsizing is required. Caution: Do not load beyond rated capacity. A built-in magnetic circuit breaker is provided on the 12 or 24 volt secondary circuit. The transformer must be installed in an accessible location to allow for resetting of the breaker in the event of overload. Electronic transformers have built-in overload protection. The use of 10 gauge conductors between the transformer and power feeds is recommended. Note: Maximum allowable voltage drop should not exceed 5%.
Sufficient wire size should be maintained in order to provide a proper operating voltage to all lamps.
When voltage and lamp brightness at the beginning of an illuminated section (close to the transformer) are higher than the voltage and lamp brightness at the end, the difference is known as “Voltage Drop.” For a proper low voltage lighting system, circuit runs must be of sufficient size wire to maintain a proper operating voltage to all lamps. Maximum allowable voltage drop should not exceed 5%.
Electronic Transformers
Maximum wiring distance (from remote transformer to start of track):
12' (Max.*) with AC Electronic Transformer (use minimum 10 ga. wire)
40' (Max.*) with DC Electronic Transformer (use minimum 10 ga. wire)
These distances may be extended with thicker gauge wire.
These transformers may be dimmed with dimmers specifically designed for use with Low Voltage Electronic Transformers. All electronic transformers offer auto-reset short circuit protection, overload protection, and thermal cut-off at 257°F. These electronic transformers will not operate without a minimum 30% load. UL Listed (UL 2108 compliant)
Magnetic Transformers
Maximum distance with Magnetic Transformer should not exceed 40.'
These transformers may be dimmed with dimmers specifically designed for use with Low Voltage Magnetic Transformers. High reliability with magnetic circuit breakers. Primary 5% boost tap provided to compensate for voltage drop on long runs of 20' or more. These UL Listed (UL
2108 compliant) transformers will operate with any load.

Connectors include a 15/16" flange with a two-piece plastic insulator washer (external)/insert (internal), allen wrench, concrete anchor 8-32 brass nut and wood screw. (Figure 1) The maximum distance allowed between ceiling connectors is 26". For sloped ceiling applications, a sloped ceiling adaptor is available.
On longer ceiling drops, use cable ceiling connectors. The cable has crimped metal sleeves on both ends that are held in place by side 1.5mm
Allen screws in the threaded brass fittings. To adjust cable length, cut with side-cutting pliers from only one end, turn the end over for 1/4" and insert the folded over cable into the center hole of the threaded brass fitting.
Lock the cable down with the 1.5mm Allen screw. Thread the brass fitting into the ceiling flange so that no brass threads are showing.
Solid Surface Installation
The surface flange can be mounted to various surfaces (ceiling or wall).
For wood surfaces, use 1/8" drill bit for the wood screw included. In concrete surfaces, use a 7/32" drill bit for the included concrete anchor.
Drywall Installation
For installation into a drywall surface, use a 1/8" toggle bolt anchor (not included) which fits through the plastic insulator of the ceiling flange. A
1/2" hole should be drilled into the drywall to properly insert the 1/8" anchor toggle wings. Toggle bolt anchors are available by others.
T-Bar Mounting
Use Con-Tech’s LA-1 15/16" Grid Stuf Type T-Bar Mounting Clip with #8-32 x 5/8" stud (Figure 2). Insert the stud through the ceiling flange and insulator. Attach the nut to the #8-32 stud and lock down using a straight blade screwdriver. Upon completion, attach the assembly to the proper location of the T-Bar ceiling. Care should be taken to add sufficient support wires to the suspended ceiling to carry the additional weight of the
Magellan Flexible Track System.
After mounting the flange in either a solid surface or a T-Bar ceiling, the support stem can now be attached (Figure 3). Screw in the vertical stem into the support flange, so that no threads are showing and tighten securely. Loosen the 1.5mm Allen screw in the track connector and rotate the lower portion of the stem assembly to align with the track section.
Remove the stem cap and insert the track into the slot of the support stem. Attach the stem cap loosely over the track and onto the stem support. Adjust the track position as desired, then tighten all stem caps and 1.5mm Allen screws securely. Max. 10 lbs. loading for stem.

For ConTech Lighting Magellan Low Voltage Flexible Track System
Magellan layouts may be made using straight or curved track sections, joined by conductive or non-conductive connectors (Figure 4). Curved track sections may also be used to create arc, serpentine, round, or any other configurations in the horizontal plane only. A Standard Curving
Machine (CRS320) is available to curve the track to your desired radius in gradual measures. Over tightening or quick radical curves can remove the anodization from the track. Con-Tech Lighting can curve the 4' rails at the factory to your specified radius for an additional charge.
Mark the track where it should be cut (if required). Cut the track with a fine tooth (32T) hacksaw blade. Smooth off any burrs with a fine file or rasp.
Conductive connectors require that the track should have 3/4" the anodization removed at the track ends, on all sides (Figure 5).
Layout the Magellan design on the floor and connect the tracks together.
Align the mounting points on the ceiling using a plumb line or laser device.
Install all the support stems and power connections on the ceiling. Starting at the power connections, begin with a single Magellan track piece and attach it to its designated support(s) and/or power stem(s). Tighten all
Allen screws and suspension tabs.
Install the connectors that the adjoining track will be attached to. The
Conductive and Non-conductive Connectors have a 3mm Allen screw that must be tightened after placing the two tracks in the connector (Figure 6).
Conductive connectors require that the track should have 3/4" the anodization removed at the track ends, on all sides. If using the Angular
Connector, tighten the (8) 2mm Allen screws and the (2) Philips screws on top and bottom to lock the angle (60° to 300°) after the two pieces of track are in the connector. The “T” Connector has (12) 2mm Allen screws, the “X" Connector has (16) 2mm Allen screws that need to be tightened after track pieces have been inserted. To lock proper angles, tighten the
Philips screw on the connector.
Bring the second track into position and attach it to the first track with the proper connector and/or power source. Secure the second track to the ceiling support(s) and tighten all Allen and Philips screws. Repeat this procedure until all of the track has been installed.
When finished, secure each end of the track run by installing the included
Track End Caps to each uncapped track end piece.
Once all the Magellan track has been installed, ensure that all connections and Allen screws are tightly secured. Never attempt to raise an assembled layout or multiple pieces of track to the ceiling as a single piece. Damage to the system may occur. Be sure that
POWER IS OFF when tightening during routine maintenance.
