Low-Voltage Enclosure Low-voltage enclosures may be either surface-mounted or flush-mounted in an electrical closet or equipment room. Both the number of enclosures and the types of components within them are customized to fit the size, lighting plan, and design of a home. Low-voltage enclosures can be distributed throughout the home near the rooms they are controlling, to provide maximum flexibility during installation of the low-voltage wiring. Low-voltage enclosures cannot house remote power modules (RPMs). 21-inch Low-Voltage Enclosure (Model # HQ-LV21-120) The twenty-one-inch low-voltage enclosure provides a compact housing for mounting up to two HomeWorks QS processors or up to two system interfaces and up to five wire landing boards (QS-WLB). The enclosure accepts one 120 V~ feed to power the panel, which is self-contained in an enclosed area, thus allowing access to only the low-voltage connections when the enclosure cover is removed.

Environment
Ambient operating temperature: 32 °F to 104 °F (0 °C to 40 °C) Ambient operating humidity: 0-90% humidity, non-condensing. Indoor use only.
Mounting
Enclosure may be surface-mounted or recess-mounted. Enclosure fits between standard 16 in (41 cm) on-center stud framing. Mount the enclosure so that line-voltage wiring will be at least 6 feet (1.8 m) from audio or electronic equipment and wiring. Mount Enclosure using one of the following methods (mounting hardware is not provided): a. S urface Mount – Use keyholes with bolts sufficient for 100 lb (45 kg) load, 1/4 in (M6) bolts recommended. b. R ecess Mount – Use screws sufficient for 100 lb (45 kg) through the corners of the enclosure. Mount enclosure fully into the stud bay, with the back flush against the inner wall surface. Enclosure is 4.088 in (104 mm) deep past cover mounting tabs (including pedestal). Enclosure cover dimensions are 21.5 in x 15.386 in (546 mm x 391 mm). NOTICE: This equipment is air-cooled. Mount in a location where the vented cover will not be blocked. 12 in (305 mm) of clearance in front of the vents is required. NOTICE: Power supply will hum slightly and internal relays will click while in use. Mount in a location where such noise is acceptable.
