MOUNTING AND WIRING

Installation shall be in accordance with all applicable regulations, wiring practices, and codes. 

Connect to a Class 2 power source only. 

•  Class 2 Device Wiring Only. – Do Not Reclassify and Install as Class 1, 3 or Power and Lighting 

Wiring. 

•  Wire connections shall be rated suitable for the wire size (lead and building wiring) employed.

The LMIO-101 is UL2043 Plenum rated.
All connections to the LMIO-101 are Class 2 low voltage.
If code requires that the LMIO-101 be mounted in an enclosure, it can be mounted inside a 4” x 4” 

junction box, inside a 21/8” deep (or deeper) 2-gang wall box, in a 3” or 4” octagonal box, or on a din 

rail inside a panel. 

Attach the LMRJ Cable

The DLM local network uses free topology low voltage wiring. The LMIO-101 can connect anywhere on the DLM local network.
