DESCRIPTION
LENC panel enclosures are designed specifically to work with all configurations of
LMCP panel interiors containing 8 to 48 relays. The enclosures are provided with
integral mounting studs that are configured to accept the panel interior making the
installation quick and easy. Covers are secured to the tubs with screws and have
keyhole style mounting. This allows the cover to be temporarily hung on the tub during
the construction phase of the project. All covers have hinged doors that expose only the
low voltage (Class 2) section of the panel and are equipped with key locks and two keys
each. All LENC enclosures are NEMA 1 rated.
A complete panel assembly includes:
• An enclosure
• A matching cover
• An interior with relays/contactors and a power supply.
The enclosure can be mounted early to allow conduit installation and rough-in wiring.
Covers are designed for flush mounting or surface mounting.
Enclosures rated for 24 or 48 relay capacity have space provided at the bottom for
optional mounting plates (DMP) to accept DIN rail mounted accessories such as multi-
pole contactors and ELCU-100 Emergency Lighting Control Units. Standard LENC24
and LENC48 enclosures will accommodate up to six four pole contactors (requires DMP
mounting plate) or four ELCU-100 units (requires DMP-1EM mounting plate). LENC8-24
and LENC24-48 enclosures have additional space provided and will accommodate up
to twelve four pole contactors (requires DMP-2 mounting plate) or 12 ELCU-100 units
(requires DMP-3EM mounting plate).
Environment
• Mount in indoor area
• 32° to 131°F (0° to 50°C)
• 10 to 95% relative humidity, non-condensing
• 15 volts/meter, 10 KHz to 2 GHz maximum RFI

MOUNTING AND INSTALLATION
Dimensions are shown on the following page. Be sure to allow adequate surface spacing for the covers.
Step 1 Mount the Enclosure
1. The enclosure should be level, plumb and rigidly installed with hardware sufficient to hold 100 lbs. (46 kg) minimum. The product
label should be in an upright, readable position.
2. Determine the appropriate wire entry locations. Make sure that all line and low voltage wiring entry locations are confined to the
appropriate compartments as shown in the diagram below.
3. Drill or knock out openings to bring wiring conduit into the enclosure. See the drawing below for details on 0-10V and network
wiring.
Multiple panels:
• For surface mounting: Allow a minimum of 0.25” between adjacent enclosures for shoebox cover clearance.
• For ush mounting: The front flange should be flush with the finished wall surface. Allow a minimum of 1.75” between adjacent
enclosures for butt alignment of flush covers.
Step 2 Install the Interior
Do not install the interior assembly until after the LMCP enclosure has been securely mounted to the wall and the conduit/wiring holes
have been drilled or knocked out.
NOTE: If this enclosure includes the optional DMP-1 Din Rail Mounting Plate (to allow for installation of EM-IN Emergency Interior
contactors), place DMP Plate over lower studs before installing the interior.
1. Place the interior in the enclosure and align the interior with the studs provided in the enclosure.
2. Attach the interior assembly to the back of the enclosure using the four sets of nuts and washers provided.
Step 3 Cover Installation
1. Drive the supplied cover mounting screws into the threaded holes until
approximately 3/8” of the thread is still exposed.
2. Hang the cover on the screws by aligning the screw heads with the
keyholes.
3. Tighten the screws to complete the installation.
4. Insert completed relay and circuit schedules and the Lighting Control Panel Interior Instructions in the plastic sleeve affixed to the
inside of the cover to complete the panel installation.
See the LMCP Installation Instructions for details on connecting the power supply and connecting the loads and line voltage to the
relays.
0–10V AND NETWORK WIRING
The Class 2 wire-way at the top of the LMCP panel is designed to provide separation between Class 1 wiring and BACnet/IRB network
wiring. All 0–10V wires must originate as Class 2 or be reclassified. The 0–10V wires are routed through multiple 1.5” openings with
grommets in the top of the Class 1/Class 2 barrier. The BACnet/IRB wires are routed through the wire-way.
