Enclosing the STB Island

Transcription

1 Enclosing the STB Island Open System Requirement All Advantys STB modules meet CE mark requirements for open equipment and should be installed in an enclosure that meets NEMA 250 type 1 requirements and IP 20 requirements conforming to IEC 529. The enclosure should be designed to prevent: unauthorized access personal injury resulting from access to live parts The specific environmental conditions under which the modules must operate should be considered in planning for the enclosure. Special consideration should be given to hazardous locations where a potentially explosive atmosphere (see page 35) may exist. NOTE: The majority of Advantys STB modules are certified for use in explosive environments. Refer to ATEX/FM Certified STB Modules (see page 37) for a complete list of modules. Size of the Enclosure The size of the enclosure is determined by the number of modules that will makeup the island. One NIM and a maximum of 32 I/O modules are permitted per island which can be: standard Advantys STB optional preferred optional standard CANopen In addition, PDMs, and an EOS or termination plate must be included in determining the total size of the island Standard Module Dimensions Advantys STB modules come in three different sizes and the dimensions for each of the sizes are listed in the following table. Module size Width of module alone Height of module in base Depth of module in base with field connectors mm (.55 in.) mm (5.05 in.) 75.5 mm (2.97 in.) mm (.73 in.) mm (5.05 in.) 75.5 mm (2.97 in.) 2-PDM 18.4 mm (.73 in.) mm (5.45 in) 79.5 mm (3.13 in.) mm (1.11 in.) mm (5.05 in.) 70.1 mm (2.76 in) These depth and height dimensions do not take into account the dimensions of external power equipment, preferred modules and/or standard CANopen devices /2009

2 The size and type of base for each of the Advantys STB modules is listed in the table on the following page.

4 Spacing Requirements Adequate clearance must be maintained between the modules installed in the enclosure and surrounding fixed objects such as wire ducts and inside surfaces. The following two illustrations show the spacing requirements within an enclosure /

5 Mounting The island is mounted on one or more 35 mm wide DIN carrier rails. For EMC compliance, a metal DIN rail must be attached to a flat metal mounting surface or mounted on an EIA rack or in a NEMA cabinet enclosure. The physical backplane for the island is established by placing a NIM and a sequence of interlocked base units on the DIN rail (see page 18). The standard DIN rail is 35 mm x 15 mm deep. For DIN rail mounting requirements (see page 74) Wiring Wiring must not obstruct the 100 mm (3.94) of free air space above and below the island segment. All wires must be secured to prevent undue load or strain on the STB modules. As shown in the side view (above), all leads from a harness or cable channel must be dressed with a service loop to reduce strain on the module. Thermal Considerations For proper heat dissipation, allow a minimum clearance of 100 mm (3.94 in) above and below each island segment. The vent openings on top and bottom of the modules must not be obstructed. Listed below are some worst-case values for estimating the wattage dissipation when you plan the cooling for your system and cabinet enclosure: Module Type Module Width Worst-case Wattage Value inputs size W size W size /2009
