Each of the M4-LHS or Extension consists of three primary enclosure components.
• The Enclosure Display Module: contains the control electronic board, display, buttons, LEDs, and electric wiring terminals.
It has two screws to hold it to the base. A program configuration switch, used to adjust the control settings, is placed above the
terminals. This switch is enclosed with the enclosure wiring cover for security. Wiring terminals are of the plug-in type to ease
installation and removal.
• The Enclosure Base: contains the holes to mount and hold the control against the wall or any flat surface. All other enclosure
components mount on the base. The bottom section of the Enclosure Base contains the wiring chamber with knockouts on the
bottom to ease installation.

secure a lock on the wiring enclosure. A plastic web that separates the wiring chamber into high and low volt sections has been
provided.
