Each contains:
Horizontal bus bar splice installation instructions for:
Procedure A - (See Note 1)1. Align and mechanically fasten the two shipping
splits or sections together. For access to the rear of the horizontal bus bars, remove the upper rear panels on the two adjacent sections that are to be spliced together. If access from the rear is not possible, remove the top cover panels instead.
2. The horizontal bus bar splices should be installed in the following order: L3, L2 and L1.

Notes:1. When the horizontal bus bars are accessible from the
rear or from the top of the motor control center by removing the rear or top panels, use Procedure A.
2. When the horizontal bus bars are accessible only from the front of the motor control center, use Procedure B.
3. The two adapters and four hex head kits supplied with the kits are required for Procedure B only.

Loose electrical connections can causedeath, serious injury or property damage.
Tighten splice connections and any connectionsloosened to install the splice to 20 lb.-ft. minimum.
3. Refer to Figure 1. Loosen the horizontal and vertical bus bar mounting hardware indicated by X’s. Loosen nuts as far as possible without removing them.
4. Refer to Figure 2.Separate front and rear horizontal bus bars and insert rearbus bar splice for:
L3 from the topL2 from the topL1 from the top
5. Refer to Figure 3.Install front bus bar splice for L3, using hardware shown. Repeat for L2 and L1.
6. Tighten all mounting hardware to 20 lb.-ft.
7. Replace panels removed in Step 1.

Procedure B - (see note 2)1. Align and mechanically fasten the two shipping splits or
sections together. Remove the top cover panels on the
If access from the rear is not possible, remove the top cover
2. The horizontal bus bar splices should be installed in the following order: L3, L2, and L1.
3. Refer to Figure 1.Loosen the horizontal and vertical bus bar mounting hardware
indicated by X's. Loosen nuts as far as possible without removing them.
4. Refer to Figures 2 and 3 (For L3 only).Separate front and rear horizontal bus bars and insert rear bus bar splice L3 from the top. Install front bus bar splice using hardware shown in Figure 3.
5. Refer to Figures 2 and 4 (For L2 only).Separate front and rear horizontal bus bars and insert rear bus bar splice for L2 from the top. Insert bus bar clamps from the rear and install nuts on the lower studs so that the upper studs do not project beyond the front horizontal bus bar (See Figure 4). Do not install front bus bar splice at this time.
6. Refer to Figures 2, 5 and 6 (For L1 only).Insert splice bar adapter on both left and right sections between orange insulator and rear horizontal bus bar as shown in Figure 5. Separate front and rear horizontal bus bars and insert rear bus bar splice L1 from the bottom. Install front bus bar splice using hardware shown in Figure 6.
7. Complete the L2 splice at this time. Pull the bus bar clamps into place and install front bus bar splice to L2 using hardware shown in Figure 3.
8. Tighten all mounting hardware to 20 lb.-ft.
Loose electrical connections cancause death, serious injury or property damage.
Tighten splice connections and anyconnections loosened to install thesplice to 20 lb-ft minimum.
