• Locate the four (4) Power Bus pieces of the splice kit in DC Link Choke
cabinet and remove shipping wrapping. See
Figure 20 .
• Connect Power Bus M+, L+, M-, L- on the red insulators in the DC Link
Choke cabinet and mating bus pieces in the capacitor cabinet. Hardware
required is pre-attached to bus connections, cabling, and insulators in the
cabinet where the power bus splice kit will attach. Remove and attach as

Figure 20 to Figure 24 .
• Torque M10 carriage bolts connecting bus to bus in the capacitor cabinet
to 29 Nm (21 ft-lb). Torque M12 hardware supplied for cable to bus stab
connections to 50 Nm (37 ft-lb).
• After cable connections have been made, ensure cable connections to
choke stabs are torqued to 50 Nm (37 ft-lb).
• Ensure a minimum of 3" (75mm) clearance exists between Medium
Voltage Bus field connections (including hardware) and all cabinet
sidesheets.
