Procedure 7
Installing and connecting the power plant frame ground leads
1 If the power system is sharing a frame ground (FG) collector cable with
other equipment, go to step 2. If the power system is not sharing a frame
ground collector cable with other equipment, go to step 3.
2 Use the appropriate two-hole lug to connect one end of a cable to the
frame ground plate at the top of the frame for a top-fed system or at the
bottom for a bottom-fed system, as shown in Figure 34 on
the appropriate torque per Table 4 depending on the size of the bolting
material used. Connect the other end of this cable to the frame ground
collector with a parallel tap connector as shown in the left side illustration
of Figure 33 on
Note: Refer to Note 2 and Table 3 on
cable size.
3 Use the appropriate two-hole lug to connect one end of a cable to the
frame ground plate at the top of the frame for a top-fed system or at the
bottom for a bottom-fed system, as shown in Figure 34 on
the appropriate torque (refer to Table 4 for torque values). Connect the
other end of this cable to the nearest Floor Ground Bar (FGB), which in
some sites may be the Building Principal Ground (BPG) as shown in the
right side illustration of Figure 33 on
4 Repeat step 2 or 3 for any other frame(s) as applicable.
