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).
Unpack the LMJA-8125/8300 controller and power module and inspect the package contents for damaged or missing components. If
damaged, notify the appropriate carrier at once and return any damaged components for immediate repair or replacement.
Included in this Package
Included in this package you should find the following items:
• (1) DLM LMJA-8125/8300 controller unit with micro SD card
• (1) Controller power supply
• (1) Wattstopper DLM quick reference guide
• (1) Wattstopper installation sheet (28957)
• (1) Accessory wiring and connector accessory pack
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.

Page 2: Material And Tools Required
PREPARATION (continued) Inserting or Removing the Micro SD Card Installation Before mounting a new controller, you must insert the included microSD flash 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. -
Page 3: Physical Mounting
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. •... -
Page 4: Tab Mounting Dimensions
MOUNTING (continued) DIN Rail Mounting Dimensions This diagram shows mounting dimensions of controller and option modules. Electronic and printed versions of this guide may not show the dimensions to scale. Verify all measurements before drilling. Tab Mounting Dimensions Measurements shown below are in inches and (mm). NOTE: DIN rail mounting is recommended over tab mounting. The LMJA-8125/8300 controller. - Page 5 INITIAL LOGIN AND SET UP - AX 3.8 (SEGMAN 2.4) Make sure that you have followed all installation instructions and that the controller is properly powered and connected to the segment network(s). 1. Connect a PC to the LAN 1 connection on the LMJA-8xxx-AX using a standard Ethernet cable (not supplied). Note that some older PCs require the use of a crossover cable for this connection.
