Introduction 2.1.2 Single 5-card Shelf HVI Cabinets and Backboard Both Single 5-card Shelf HVI Backboard (751960/05) and HVI Cabinets (751960/15, 751960/15CU5, 751960/15CU7) have the same functionality and require the same connections and power input. The difference between them being that the HVI Cabinet assemblies have temperature controls and can be installed outdoors as well as indoors while the Backboard can only be installed indoors.
Teleline 5-card Shelf HVI Cabinets and Backboard with Optional NIU HVI Equipment Layout - Concept All equipment that is subject to the effects of the remote ground aspect of the site is grouped and located on the High Voltage Side and the Low Voltage side of the HVI unit.
Page 19
HVI Equipment Layout - Concept stood upon. Therefore care should be taken when handling circuit equipment and or wiring. The Teleline equipment is designed to isolate the personnel and equipment from the effects of the high and the low voltage condition of this site.
Teleline 5-card Shelf HVI Cabinets and Backboard with Optional NIU 300 Volt Point Location 2.3.1 Cable Shields The 300 V point for an installation is defined by the electrical parameters of the substation. This is the point where the Ground Potential Rise of the site is reduced to 300 V or less.
300 Volt Point Location in this closure and routes into the substation switch room will be called the dedicated cable. Any other cables located in this closure will be referred to as other cable(s). Splicing of the general use cable pairs to the dedicated cable pairs in this closure must follow the following rules: All pairs spliced from the general use cable to the dedicated cable must not be spliced using modular connectors.
nonmetallic conduit should not cross or come in contact with any grounded conductive surface. 2.3.3 Cable Routing Station Side Metallic Conduit The station cable(s) that terminate on the HVI backboard should be routed to this backboard utilizing a metallic conduit. If the distance between origination point and the termination point of the HVI backboard is substantial, greater than 30 m (100 feet), then a #2 copper bonding conductor should be run with the station cables either...
