2.6 GROUNDING INSTALLATION

#1 Lug

Connect a #6 THHN bare ground wire to the TOP RIGHT (first) copper lug on the common ground bracket assembly to all RTL kits (make this by taking a length of the #6 THHN wire and stripping it). If multiple surge arrestor boxes are used, run the #6 THHN wire through the lugs of all boxes in a straight line. Tighten all clamps securely using the proper size screwdriver ( 1/4" flatblade).

#2 Lug

It is very important to connect the earth ground wire to lug #2, the lug opposite the CPP Cabinet lug and RTL kits lugs. Refer to Figure 2-5for acorrect

placement of the connections on the common ground bracket assembly. Use #4 THHN wire to connect to the ground clamp.

#3 Lug

Connect a #6 THHN wire to lug #3 (third from top) on the common ground bracket assembly to the ground lug in the CPP cabinet. Refer to Figure 2-5for the location of the ground lug in the CPP cabinet.

#4, #5 Lug

Connect a #6 THHN ground wire from lugs 4, 5, etc. of the ground bracket assembly to the ground lug on each console position. A ground lug and hardware has been furnished with the cable kit for each console.
