OVERVIEW

The Legrand/Wattstopper LMJA-8125/LMJA-8300 is a network controller
that provides advanced building management and automation features for
customers using Digital Lighting Management (DLM) BACnet-based networks
and devices. Powered by the Tridium Niagara platform, the controller can
be ordered with either the N4 or AX 3.8 (LMJA-8xxx-AX) Segman 2.4
station. The LMJA-8xxx Network controller hardware running are licensed
for use with Wattstopper DLM. When used with a DLM wired or wireless
network segments the LMJA-8xxx series network controllers provide global
control, monitoring, adjustment, scheduling, and support for graphics. Larger
buildings and campus deployments with multiple network controllers can
also communicate to a supervisor software for a single point of BACnet
management and monitoring. The LMJA-8xxx series can be configured to
work with just DLM platform or can be integrated into an existing 3rd party
Building Management System (BMS).

Safety Precautions

The following items are warnings of a general nature relating to the installation and start-up of the LMJA-8xxx. Be sure to heed these
warnings to prevent personal injury or equipment damage.

WARNING

• Disconnect power before installation or servicing to prevent electrical shock or equipment damage.

• Make all connections in accordance with national and local electrical codes. Use copper conductors only.

• To reduce the risk of fire or electrical shock, install in a controlled environment relatively free of contaminants.

• This device is only intended for use as a monitoring and control device. To prevent data loss or equipment damage, do not
use it for any other purpose.

Static Discharge Precautions

Static charges produce voltages high enough to damage electronic components. The microprocessors and associated circuitry within a
Segment Manager are sensitive to static discharge. Follow these precautions when installing, servicing, or operating the system:

CAUTION

• Work in a static-free area.

• Discharge any static electricity you may have accumulated. Discharge static electricity by touching a securely grounded
object.

• Do not handle the printed circuit board (PCB) without proper protection against static discharge. Use a wrist strap when
handling PCBs. The wrist strap clamp must be secured to earth ground.

PREPARATION (continued)

Inserting or Removing the Micro SD Card Installation

Before mounting a new controller, you must insert the included microSD ash memory card. Note the card has the unique Niagara

identity (host ID) for the unit, set at the factory. ALL power to the controller must be removed. If the unit is currently running, initiate a
controller shutdown.

1. Access shutter for microSD card (slide down/up to
open/close)

2. Card carrier inside controller

3. MicroSD card to insert or remove from card carrier

1. Carefully slide the plastic microSD card shutter open. The shutter should remain captive in the base, revealing the microSD card
socket.

2. To insert the microSD card, slide it into the card carrier, label side up, until the spring catch engages. If properly inserted, the card is
behind the shutter track.

3. To remove the microSD card, push it in, until the spring release pushes it partially out of the card carrier. Grasp the card, pull it
completely out of the unit and store it in a static-free protective case.

4. Carefully slide the card shutter back over the card carrier opening, until it clicks into place. When properly closed, the shutter should
not protrude behind the mounting base.

NOTE: Data on the microSD card is encrypted. If you swap in a card from a previously configured unit, you must change the LMJA-

8125/8300 system passphrase on the platform to match the passphrase on the new microSD card. Typically, the microSD card never
needs removal. However, in the case where a controller has been electrically damaged or found faulty, you can remove the card and
install it in another like unit, so it can become a functional replacement.

MATERIAL AND TOOLS REQUIRED

• One of the following:

▸ UL Listed, Class 2, 24VAC transformer, rated at minimum of 24VA. A dedicated transformer is required (cannot power additional

equipment), -OR­ ▸ 24VDC power supply, capable of supplying at least 1A (24W), -OR-
▸ NB-PS1 wall-mount AC power adapter with barrel connector plug

• DIN rail, type NS35/7.5 (35mm x 7.5mm_ and DIN rail end-clips (stop clips), recommended for any installation with option modules.

• Suitable tools, fasteners, and accessories for mounting

MOUNTING

Mount the LMJA-8125/8300 controller in a location that allows clearance for wiring, servicing, and module removal.

Environmental Requirements

Note the following requirements for the LMJA-8125/8300 controller mounting location:

• This product is intended for indoor use only. Altitude to 6,562 ft (2,000m).

• Ambient conditions must be within the range of: Operating Temperature: -4°F to 140°F (-20°C to 60°C), Storage Temperature: -40°F
to 185°F (-40°C to 85°C)

• Relative Humidity: 5% to 95% non-condensing, Pollution Degree 3

• Supply (mains) voltage requirements: Allowable voltage fluctuation +/- 10%

• Do not expose the unit to ambient conditions outside of the range of 0ºC (32º F) to 50ºC (122º F) and relative humidity outside the
range 5% to 95% non-condensing.

• If mounting inside an enclosure, that enclosure should be designed to keep the unit within its required operating range considering
a 24-watt dissipation by the controller, plus dissipation from any other devices installed in the same enclosure. This is especially
important if the controller is mounted inside an enclosure with other heat producing equipment.

• Do not mount the unit:

▸ In an area where excessive moisture, corrosive fumes, or explosive vapors are present
▸ Where vibration or shock is likely to occur
▸ In a location subject to electrical noise, including the proximity of large electrical conductors, electrical machinery, welding

equipment, spark igniters, and variable frequency drives, etc.

MOUNTING (continued)

Physical Mounting

The following information applies to physically mounting the unit.

• You can mount the LMJA-8125/8300 in any orientation. Horizontal mounting (as shown) is strongly recommended to achieve
maximum heat dissipation and meet the operating temperature upper limit. Any other mounting orientation reduces this upper limit.

• Mounting on a 35mm wide DIN rail is recommended. The LMJA-8125/8300 unit base has a molded DIN rail slot and locking clip.
DIN rail mounting ensure alignment of the connectors between all devices.

• If DIN rail mounting is impractical, you can use screws in mounting tabs on the controller (see next page)

• The LMNC-ENC1 is an optional DIN rail equipped enclosure. The LMNC-ENC1 provides an integral 120VAC receptacle, conduit
connection points and protection for the LMJA-8xxx. It is designed for applications where code or the local AHJ requires that low
voltage wiring such as control and communication wiring be run inside conduit, or where needed for customer specifications. See
the instructions provided with the LMNC-ENC1 for more information.

• The LMJA-8125/8300 controller can also be mounted in an LMNC enclosure, where multiple NB-Routers and an NB-Switch are
used

NOTE: To remove a unit from the DIN rail, pull
down its locking clip, then swing the bottom
out and lift the unity away from the DIN rail.

To mount on third-party DIN rail
