DESCRIPTION
Leviton Quantran mBus control stations are a flexible, easy to configure control interface to Quantran mBus load control devices. Offered in multiple scene
configurations and finishes, a device is available to fit every lighting control need.
WARNINGS AND CAUTIONS
• WARNING: TO AVOID SERIOUS PERSONAL INJURY never push
objects of any kind into this product through openings, as they may touch
dangerous voltages.
• WARNING: TO AVOID SERIOUS PERSONAL INJURY never touch
uninsulated wires or terminals unless the wiring has been disconnected at
the network interface.
• Read and understand all instructions. Follow all warnings and instructions
marked on the product.
WARNINGS AND CAUTIONS
• Never install communications wiring or components during a lightning storm.
• Never install communications components in wet locations unless the
components are designed specifically for use in wet locations.
• Use caution when installing or modifying communications wiring or
components.
• Do not use this product near water - e.g., near a tub, wash basin, kitchen
sink or laundry tub, in a wet basement, or near a swimming pool.
• SAVE THESE INSTRUCTIONS.

•
Connect Data+, Data-, Common, +V, and shield at every station (see
Table 1).
•
Do not splice control wire
•
Shield shall be connected to ground at the dimmer rack and must only be
connected to ground at one point in the system.
•
Capacitance of wire shall be 15pF/ft. or less.
•
Normal Impedance of wire shall be between 100-120 ohms.
•
A second pair of stranded wire is required for the power.
•
We strongly recommend the use of either Leviton #WIRLN-500, Belden
1502R, or equivalent be used for wire runs.
Table 1
Pin # Function Notes
1 Data + Connect on every station, use one conductor of a twisted pair
2 Data - Connect on every station, use the second conductor of a twisted pair
3 Common Connect on every station – even if not using power
4 +V +12-24Vdc
Use RS485 compatible cable for communications. RS-485 requires a single
Twisted Pair, 24 AWG minimum.
TERMINATIONS
•
Scene buttons are used to recall pre-programmed scenes. Reference
dimmer modules installation instructions for details on programming.
•
Raise/Lower buttons are used to raise or lower the last selected scene.
•
Off turns the lights off.
•
The IR Receiver can be used with the IR remote to execute the above
functions.
OPERATION
Input: mBus Stations Require 8-18VDC
Current draw: 10mA
Standard dc Voltage Drop calculations should be used to ensure that your
voltage is always greater than the minimum. If you’re using 18AWG Belden
1502R with a resistance of 0.0069ohms/foot, the following formula can be
used:
Vdrop=Total Load (Amps) * Run Length (Feet) * 0.0069 Ohms/Foot
NOTE: Assuming you’re using a 12Vdc Supply, and you’ll allow a voltage drop
of 12V-8V=4V, the formula can be simplified to:
Max Run (Feet) =4/(Total Load (Amps)*0.0069)
POWER CONSIDERATIONS
NOTE: The mounting surface must be flat to avoid distortion of the back plate,
which may prevent the cover plate fitting correctly. For the same reason, do
not over-tighten the fixing screws.
INSTALLATION
• Product is designed to fit into a single gang 3” x 3” back box, not included.
• Follow best industry practices for installation
• Product requires commissioning by a Leviton field commissioning agent
after installation.
