Driver Wiring and Mounting

  • Driver is grounded by a mounting screw to the grounded fixture or by a terminal connection.
  • It is possible to daisy-chain the T-Series digital link using the second set of terminal blocks. See example on page 10
  •  Fixture must be grounded in accordance with local and national electrical codes
  • The positive terminals of both output channels are electrically connected inside the driver. This supports the use of common anode loads
  •  Terminal blocks on the driver accept one solid wire per terminal from 20 AWG to 16 AWG (0.5 mm)
  • Maximum driver-to-LED light engine wire length for:
Wire Gauge Maximum Lead Length
150 mA to
700 mA
710 mA to
1.50 A
1.51 A to
2.10 A
18 AWG (0.75 mm2) 30 ft (9 m) 15 ft (4.5 m) 10 ft (3 m)
16 AWG (1.5 mm2) 35 ft (10.5 m) 25 ft (7.5 m) 15 ft (4.5 m)
14 AWG (2.5 mm2)4 50 ft (15 m) 40 ft (12 m) 25 ft (7.5 m)
12 AWG (4.0 mm2)4 100 ft (30 m) 60 ft (18 m) 40 ft (12 m)
  1. For best tunable white performance, operate at 1% or higher. Light output at the low-end depends on the efficacy of the LED light engine used with the driver.
  2. To maintain the warranty, the installer is responsible for ensuring that the driver calibration point does not exceed 167 ºF (75 ºC) for W case and 158 ºF (70 ºC) for Y case.
  3.  Where ta is the temperature of the air directly surrounding the driver.
  4.  Terminal blocks on the drivers accept only solid 20 AWG to 16 AWG (0.5 mm 2to 1.5 mm 2 ) wire. To use wire gauges larger than the terminal blocks’ rated gauge of 16 AWG (1.5 mm 2 ), connect up to 3 ft (1.0 m) of 20 AWG to 16 AWG (0.5 mm 2 to 1.5 mm 2 ) wire to the LED driver terminal blocks, then connect 12 AWG or 14 AWG
    (4.0 or 2.5 mm 2) up to the length allowed in the above table.

How to Determine Compatibility Between an LED Driver and LED Load

  1. Review the specifications of the LED load.
  2. Identify the minimum and maximum operating voltage of the LED load at the desired operating current. This “current” will be the rated output current of the LED driver. Consult the LED load manufacturer for any questions.
    Example: An LED load that is rated at 0.7 A and 30 V nominally, has an input (forward) voltage range of
    25 – 35 V (at 0.7 A) due to unit-to-unit variation, temperature, etc.
  3.  Examine the LED driver Load Compatibility graphs below for each output range to ensure that the voltage range of the LED load is within the load compatibility range.
    Example: Lines* marked below indicate two load specifications:
    Load A (25 – 35 V) at 0.5 A
    Load B (25 – 35 V) at 0.7 A

Load A (Compatible)
The operating voltage range for load A is 25 – 35 V at 0.5 A. Since the load specifications are within the operating range, the combination of LED load and LED driver is compatible.

Load B (Not Compatible)
Since the maximum voltage of the load, 35 V, exceeds the 28.5 V allowable at 0.7 A, this combination of LED load and LED driver is not compatible.

Load Compatibility

4.The LED Driver Selection Tool (www.lutron.com/drivers) is a website compatibility tool that allows for a fast compatibility search of all Lutron LED drivers that are compatible with an LED load.
5See T-Series Model Number to create the appropriate model number for the desired driver. T-Series drivers are only available as “BLK” drivers for use with QwikFig Air.

* Lines are an example and not the range of the T-Series LED driver.

Tunable White Considerations

  • The driver will consume two digital addresses:
    – Address N controls intensity*
    – Address N+1 controls color temperature*
  • The highest kelvin light source must be connected to channel 1 (cool white).
  • The lowest kelvin light source must be connected to channel 2 (warm white).
  • The driver can accept LED light sources with a physical CCT value between 1500 K and 6500 K.
  • The driver default minimum intensity level is set to 1%.
    See the Tunable White Capability figure to the right for more information.
  • Operation below 1% may be acceptable in some applications. The minimum level can be adjusted below 1% through the Quantum software. See the Tunable White Capability figure to the right for understanding the general trade-off of dimming range versus color temperature range.
  • For optimal tunable white performance, it is recommended to set high-end and low-end logical trims which reduce the overall CCT range to less than the maximum capacity of the light source.

Tunable White Capability

* This is the default behavior. During commissioning, the system may change the addresses to be non-consecutive.

T-Series Wiring

T-Series Digital Link Overview

  • The T-Series digital link wiring (T1 and T2) connects the digital ballasts and drivers together to form a lighting control system.
  • T1 and T2 (T-Series digital link wires) are polarity-insensitive and can be wired in any topology (e.g., T-tap and daisy-chain).
  • Power is supplied to the T-Series digital link from the control system.
    T-Series Digital Link Wiring
  •  Make sure that the supply breaker to the drivers and T-Series digital link supply is OFF when wiring.
  • Connect the two conductors to the two driver terminals T1 and T2 as shown.
  • Using two different colors for T1 and T2 will reduce confusion when wiring several drivers together.
  • There are two sets of T-Series digital link terminal blocks to support daisy chaining the link.
  • The T-Series digital link may be wired Class 1 or Class 2. Consult applicable electrical codes for proper wiring practices. Please refer to Lutron Application Note #142 (048162) at www.lutron.com for more information.
  • For emergency lighting wiring, please refer to Lutron Application Note #106 (048106) at www.lutron.com

• The T-Series digital link supply does not have to be located at the end of the digital link.
• The Maximum Wire Length table below gives the limits for each of the wires in the T-Series digital link pair.
• The T-Series digital link length is limited by the wire gauge used for T1 and T2 as follows:

Wire Gauge Maximum Wire Length
12 AWG 1000 ft
14 AWG 1000 ft
16 AWG 900 ft
18 AWG 550 ft
Wire Size Maximum Wire Length
4.0 mm2 300 m *
2.5 mm2 300 m *
1.5 mm2 300 m
1.0 mm2 207 m
0.75 mm2 155 m
