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.
CAUTION
