Large System Installation and Commissioning

The NT8D64BF Floor Mounting Kit provides the hardware required to 
secure a Large System column to concrete floors for non-seismic 
installations, that is, for a non-Bellcore or OSHPD approved installation.

The kit provides four sets of hardware, however, a minimum of two anchors 
must be used diagonally opposite to secure the column pedestal to the floor. 
The kit also provides four insulating washers that can be used during kit 
installation.

The NT8D6401 Insulating Washer Kit is used for attaching the Large System 
to the floor when the installer is using a third party anchor kit instead of the 
Nortel NT8D64BF Floor Mounting Kit.

In this case, one NT8D6401 Insulating Washer Kit is required for each 
pedestal to electrically insulate the mounting bolts from the pedestal casting. 
Each NT8D6401 Insulating Washer Kit provides four insulating washers.

Follow Procedure 69 to install a Floor Mounting Kit (NT8D64BF).

Mark the position of each Meridian 1 column using the equipment room 
floor plan.

Mark the location of all four anchor holes for each column using a dark 
marking pencil.

Center-punch the center of each hole in the concrete.

Make the hole in concrete by using a rotary hammer drill to the following 
size and depth:

•

hole diameter 16 mm (5/8 in.)

•

hole depth 50 mm (2 in.)
