9.10 CABLE/UTILITY MANAGEMENT SYSTEM

9.10.1 USAGE WITH ENCLOSED ELECTRICAL/ELECTRONIC EQUIPMENT

In certain locations cable supports and/or enclosures are installed for dedicated usage with

enclosed electrical/electronic equipment. For these situations it is acceptable for these

cable/utility management systems to be utilized for the required purposes of the equipment. This

may include a bundle of cables, hoses, and tubing that is required to be run from the equipment

console to the unit under test. In these situations the use of a cable/utility management system

is considered to be a part of custom-made equipment consisting of enclosed electrical/electronic

equipment, cabling, cable/utility management system, and unit under test with associated

equipment (See Figure 9-6).

In cable/utility management systems where cables other than those of the equipment exist, the

decision should be documented that any risk posed by the situation is acceptable for the

operation to be performed and to the functions of the existing cables.
