Step 1.
Connect line side or “hot” side of the low voltage connection.
Start with position # 1.
Step 2.
Connect common side to one of the low voltage terminal blocks.
-
Repeat step 1 & 2 for every new lead connection. 14. L.V. Secondary feeds go to a 85 AMP rated terminal block. Each terminal is UL listed to have the following capacity:
6 #14
4 #12
4 #10
2 #8- *For longer runs you may need to go to a higher tap & or larger wire gauge on secondary side.

120VAC 12 VAC
*( ) CONNECT TO ANY TAP**
– USE SECONDARY TERMINAL BLOCKS FOR LOAD CONNECTIONS
– DASHED LINES INDICATE ELECTRICAL CONTRACTOR WIRING
– MULTIPLE LOADS CAN BE CONNECTED TO THE SAME OR DIFFERENT TAPS, DEPENDING ON
DESIRED OUTPUT VOLTAGE, TO COMPENSATE FOR VARYING LOAD DISTANCES.

Selecting the Right Tap
Conclusion:
With a simple field adjustment, the contractor was able to recover his voltage
drop and light output by switching from Tap 12 to Tap 15.
A 12V Lamp Operating at 10V = 50 % Light Output!

The Impact of Voltage Drop on Light Output
*For longer runs you may need to go to a higher tap & or larger wire gauge on secondary side.
* Use a True RMS Volt Meter when a dimmer is used.
(RMS = Root Mean Squared)
- The “line side” of the load is connected to secondary circuit breakers.

Warnings
WARNING
FOR CONDUIT CONNECTION
RISK OF ELECTRIC SHOCK.
Install power unit 5 feet (1.5 m) or more from the pool or spa and 10 feet
(3.05 m) or more from a fountain. Where the power unit is installed within 10
feet (3.05 m) of a pool or spa, connect unit to GFCI protected branch circuit.
FOR POWER SUPPLY CORD CONNECTION
RISK OF ELECTRIC SHOCK.
Install power unit 5 feet (1.5 m) or more from the pool, spa, or fountain.
Where the power unit is installed (a) indoors within 10 feet (3.05 m) of a
pool, spa, or fountain or (b) outdoors, connect power unit to a receptacle
protected by a GFCI.
RISK OF FIRE. If installation requires running wire through a building structure, special wiring methods are needed. Contact a qualified electrician.
OUTDOOR CORD – connected unit shall be connected to a GFCI protected hooded flush type cover plate recepticle marked “Wet Location.
DO NOT USE EXTENSION CHORDS.
The main Secondary Wiring is intended for shallow burial – less than 6 inches (152 mm) For Supply connections use wire rated for at least 60C.
- To order additional lengths of wire for connection in the secondary, contact your local distributor or Q-Tran at 203-367-8777 and inquire about Q-Wire.
