Legrand MR2000 - Manual (Page 3)

WIRING INSTRUCTIONS
1. Disconnect power to the circuit by turning the circuit
breaker OFF before installation.
WARNING
TURN THE POWER OFF AT THE CIRCUIT
BREAKER BEFORE INSTALLING THE DIMMER.
2. Strip existing wire ½” (12.7mm).
3. Wire the LINE (black), NEUTRAL (white) and LOAD lead
wires to the supply/load wires per Figure 2. If installing
in a grounded metal box, the unit will be grounded to
the electrical box. Otherwise, use the green ground
screw to connect to ground as shown in Figure 2. Use
#12AWG copper wire. Depending on the application and
the number of connections, more space may be needed.
If so, use an appropriate size box or box extension.
4. If the MR2000 will be controlled by a wired multilocation
controller (MCD68/DCD68) connect the yellow traveler
wire per the instructions provided with the controller.
If using the MR2000 in a Miro wireless network, the
yellow traveler wire is not used and must be capped.
5. Switch the circuit breaker back ON.
6. If the unit is to be controlled from a Miro wireless
device, refer to “SET HOUSE ID” on the next page.
INSTALL IN COMPLIANCE WITH ALL APPLICABLE CODES
& STANDARDS. Failure to follow these instructions may
cause personal injury or equipment damage.

Figure 2 - Wiring Diagram
A Miro 2000W Dimmer is compatible with wired Miro
devices, as shown above connected by a traveler wire
between the MR2000 and the Multilocation Controller (either
MCD68 or DCD68). It will also communicate with a wireless
Miro network (see Figure 1).
INSTALLATION
The unit must be installed in compliance with the
Environment and Orientation instructions.
CAUTION
Disconnect power when servicing fixture
or changing lamps. Both lighting fixture
and dimmer must be grounded. Use
this device only with copper wire.
Radio communication cannot be guaranteed if the unit is
mounted in a metallic electrical enclosure.
1. Install dimmer in a 21/
8
” minimum deep 4” square (1900)
electrical box with a 1½” extension. Extension must
extend beyond wall such that the heatsink is spaced a
minimum of 1½” from the wall.
2. For both wall and plenum mounting, orient the dimmer
so that the heat sink fins run vertically, allowing natural
upward convection.
3. Allow a minimum of 6” space above and below the unit
and do not block vertical airflow through the heat sink.
Requires 100 BTU/hour ventilation.
