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
To mount on third-party DIN rail
The following procedure provides step-by-step DIN rail mounting instructions for the LMJA-8125/8300. It is recommended to leave 2
inches of clearance above and below the unit.
1. Pull the controller’s locking clip down.
2. Tilt the controller to hook over the DIN rail.
3. Push down and in on the unit, fastening to the rail.
4. Push the locking clip up to secure.
5. Mount any option module (RS-485 Module) onto the DIN rail in the same way.
6. Carefully secure both ends of the final assembly with DIN rail end-clips provided by the DIN rail vendor.
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.
