The LMRC-611MCC-A room controller includes an antenna for wireless performance and gasketed sealed connectors allowing it to be
mounted inside a junction box to adhere to local requirements and codes such as Chicago Plenum.
The LMRC-611MCC-A can be installed in a deep junction box with 3/4" knockouts. Recommended junction box for Chicago Plenum or conduit
requirements: Garvin Industries 4-11/16 Chicago Plenum Air Tight Junction Box, 2-1/8 in. Item #72171-3/4-VT or equivalent
NOTE: The LMRC-611MCC-A should be mounted in a vertical orientation as shown in the following wiring diagrams, with the antenna
pointing down.
The included Conduit Adapter is required when installing the LMRC-611MCC-A within a box. An optional 3/4" rigid box spacer (not
included) can be added to help secure the two junction boxes
The included Antenna Gland is used to secure the antenna and can be installed on any 3/4" knockout.
Line voltage wires are #16 AWG. The relay is rated for up to 10A; total load for LMRC-611MCC-A not to exceed 10A. On/Off or 0–10V
dimming loads can connect to any load relay.
For dimming ballasts, either or both the Class 1 and Class 2 0–10V wires may be connected. For Class 1 Dimming, wires are 18# AWG.
Class 1 is preferred in new installations when the purple and pink dimming signal wires are included in the fixture power cable. Class 2
is used for new or existing installation when it is easier to run the purple and pink dimming signal wires outside the fixture cable.
Class 1 and Class 2 wiring should be maintained throughout the installation and cannot
be swapped—appropriate wiring practices should be used. Class 1 and Class 2 circuitry
in the LMRC-611MCC-A units are galvanically isolated.
Before starting installation punch out designated knockouts, as shown.
In addition, adjust the lock nut on the LMRC-611MCC-A nipple so that at least
1/4" will stick out from junction box, once it is inserted into the knockout.
Step 1 Attach the Rigid Box Spacer (Optional)
If using a 3/4" rigid box spacer to help secure the two junction boxes, attach it to the
same side as the conduit adapter, as shown, and secure with lock nut.
Step 2 Attach the Antenna Gland and Mount Room Controller in J-box
Feed the wires from the LMRC-611MCC-A through the knockout as shown, and lower the
room controller into the junction box. Next, slide the lock nut over the antenna, then feed
the antenna through the knockout and then through the antenna gland, as shown. Finally,
insert the antenna gland into the knockout and fasten to the J-box using the lock nut. Pull
antenna through gland if there is excess antenna within the J-box. Make sure that there is
at least 4 inches of exposed antenna beyond the antenna gland.
IMPORTANT: Be careful not to bend the antenna excessively. Doing so may break the
Antenna.
NOTE: If local regulations require no polymeric materials in the plenum space, you will
need to strip the insulation surrounding the antenna. After feeding the antenna
through the antenna gland and securing the gland, mark the antenna where it
exits the gland as, shown in Figure 1.
Unscrew the cap section of the gland and remove the metal washer and rubber
grommet insulator as shown in Figure 2, then strip the insulation at the mark,
using an 18AWG wire stripper. Then reattach the rubber grommet and metal
washer and screw the cap section back on, making sure no insulation exits the
gland, as shown in Figure 4. Ensure that bare antenna does not touch any metal.
