PRELIMINARY
Mounting the MLC to a  wall or furniture
1.  If you have an MLC 226 IP Series model other than the MLC 226 IP L, remove 
the four faceplate attachment screws and remove the original faceplate, if 
applicable.
2.  If you have a model other than the MLC 226 IP L, attach the optional lectern 
mounting faceplate to the MLC with the screws removed in step 1.
3.  With power disconnected at the source, insert the MLC into the wall or 
furniture.
4.  Fasten the MLC and faceplate directly to the furniture or wall using wood 
screws.
N
  If the MLC (and any accessories such as control modules or an IR Link) is not 
mounted to a grounded metal wall box, 
•  Ground each faceplate directly to an earth ground. Or...
•  Tie each faceplate to its circuit board and power supply via a ground pin on 
one of the connectors.
Do not tie a product’s faceplate to both a separate earth ground and the circuit 
ground (via a connector pin). If you tie a product to two different ground 
sources, you may introduce ground loops or other grounding-related problems 
into the system.
N
  For the installation to meet UL requirements and to comply with National 
Electrical Code (NEC), the MLC must be installed in a UL approved junction 
box. The end user or installer must furnish the junction box; it is not included 
with the MLC. See “Mounting the MLC to an electrical box or mud ring” on 
the previous page.
  Rack mounting an  MLC 226 IP L
1.  Attach an MLC 226 IP L to an optional rack mounting faceplate (UCM-RAAP) 
with the provided mounting machine screws and nuts.
2.  With power disconnected at the source, fasten the MLC and faceplate to the 
rack using the supplied machine screws as shown in the following illustration.
