Equipment Rack

Incubator. When laboratory work required an incubator with an internal electrical outlet for a mixing machine, such a thing could not be found in the catalogs. Even if it had been available, the

For loading operations the column is clamped to the equipment rack and is connected with flexible polyethylene tubing. The top of the column can either be connected to the feed head tank or be left open for adding resin and solutions directly to the column. Each quartz column is normally reused throughout a complete series of consecutive runs, usually five to nine runs, before it is discarded. 

Typical "plant equipment is shown in Fig. 3. The equipment racks are assembled and tested before being installed in hot cells. This rack, which served for some five years, has one high-pressure pump, a short "loading column, two long elution columns, and appropriate associated valves, feed vessels, product collection apparatus, and plumbing. Resin was periodically replaced by hydraulic transfer. 

FIGURE 10.270 Recommended grounding method for equipment racks. To make assembly of multiple racks easier, position the ground connections and AC receptacles at the same location in all racks. 

Follow similar grounding rules for simple one-rack equipment installations. Figure 10.273 illustrates the grounding method for a single open-frame equipment rack The vertical ground bus is supported by insulators, and individual jumpers are connected from the ground rail to each chassis.

As faculties expand in size and complexity, a set of conventions will no longer answer all of the questions. At some point, a wire leaves an equipment rack and its destination is no longer obvious. Likewise, equipment wUl often require written documentation as to its configuration and purpose, especially if it is utilized in an uncharacteristic way. 

Rack An equipment rack, usually measuring 19 in (48.26 cm) wide at the front mounting rails. 

Any device intended for internal or external carriage, mounted on aircraft suspension and release equipment, and which may or may not be intended to be separated in flight from the aircraft. Stores include missiles, rockets, bombs, nuclear weapons, mines, fuel and spray tanks, torpedoes, detachable fuel and spray tanks, dispensers, pods, targets, chaff and flares including external dispensing equipment, and suspension equipment (racks, pylons). Note that individual rockets, gun rounds, and submunitions are not considered to be stores. 

Most essential facilities are dependent on effective communication after an earthquake. Hard line and ceU telephone may not be functional, and backup systems should be provided. Equipment racks used for communication equipment must be able to withstand the shaking. Radio frequencies should be checked for compatibility with outside entities that must be contacted. Shortwave radio and satellite telephones are possible backup systems. Large or multi-site facilities may also need to maintain internal communication, and the viability of the existing systems should be considered. 

When pallets, loads, ladders, roll cages, and other powered equipment are located in aisleways, it is not unusual for rack damage to occur. This damage is the result of improper clearance between the equipment, racking, and the object. These collisions can also cause racking collapse or lead to future collapse.
