TeleLite ZOI CFJ Backboard Assembly
with two 7-slot shelves

The TeleLite 724220/05 Backboard Assembly is specially equipped for placement of the Copper Fiber Junction (CFJ) within the zone of influence (ZOI) of a substation. The treated plywood backboard is painted red, is equipped with two 7-slot shelves, ADC Isolation Jacks, two 66-type punch blocks for cross-connect, and has no provision for a local ground connection due to the inherent nature of the hazards associated with a CFJ placed within the ZOI of a substation. Installation technicians must be advised NOT to ground this assembly inside the ZOI unless specifically directed to do so by a competent authority.

The TeleLite 724220/05 Backboard Assembly is designed to be mounted in either a suitable weather resistant cabinet, or onto an interior wall.
