5600 Free Standing System Enclosures

SST Model 5600 System Enclosures are a convenient way to mount your NOVA-5000 Detection and Control System in locations where a free-standing enclosure is desired. The enclosure provides standard 19 inch wide mounting spaces for Model 5300 16 position module racks. The smaller 28 inch high enclosure is suitable for mounting on a table or control room console. The larger 79 inch high enclosures are for floor mounting. The 79 inch rack is available with a rear door for locations where back access is available. Where rear access to the equipment enclosure is not possible, the front access version is used to mount the module racks on a swingout frame, and the rear door is replaced with a solid panel.

The NOVA-5000 System Racks (Model 5300) should be mounted in the front section, starting at the top. At least one rack mounting space should be allowed above each rack for mounting nameplates and to provide proper ventilation for the module components. Each rack and the associated nameplate space requires 4 rack units (4U) space in the enclosure. If backup batteries are required for the system, it is convenient to leave enough unused space at the bottom of the enclosure to allow the batteries to sit on the bottom pan of the enclosure. The incoming wires from the field devices should connect to terminal blocks mounted on the side panels of the enclosure. Then use smaller, more flexible wires to connect the racks to the field terminal blocks. System power supplies should also be mounted in the lower part of the enclosure.

The system enclosure shall be a free standing (floor or table) mounted unit with arrangement to permit access to all terminals and components on the rear of the module mounting racks. There shall be a key-locked front door with viewing window. Removable gland plates shall be provided on the bottom of the enclosure for field installation of cable glands or conduit connectors. The unit shall be sealed and approved for NEMA12/IP55 applications. Safety Systems Technology Model 5600 Free Standing System Enclosure, or equivalent, shall be supplied.
