For example, if <br /> the MDF-300(A) is set to address "26", then it will automati- <br /> cally assign itself to addresses "26" and "27" <br /> NOTE: "Ones" addresses on the MDF300(A) are 0, 2, 4, 6, or 8 <br /> only. Terminals 6 and 7 use the first address, and terminals 8 and <br /> 9 use the second address. <br /> Q CAUTION: <br /> Avoid duplicating addresses on the system <br /> Installation <br /> MMF-300(A), MMF-302(A), and MDF-300(A) modules mount <br /> directly to a standard 4" (10.16 cm) square, 2.125" (5.398 cm) <br /> deep, electrical box. They may also be mounted to the <br /> SMB500 surface-mount box. Mounting hardware and installa- <br /> tion instructions are provided with each module. All wiring <br /> must conform to applicable local codes, ordinances, and regu- <br /> lations. These modules are intended for power-limited wiring <br /> only. <br /> The MMF-301(A) module is intended to be wired and mounted <br /> without rigid connections inside a standard electrical box. All <br /> wiring must conform to applicable local codes, ordinances, and <br /> regulations. <br /> Agency Listings and Approvals <br /> In some cases, certain modules may not be listed by certain <br /> approval agencies, or listing may be in process.
