8. Gain access to supplied HRNS-JMPR AUTO NTRL RLY (P/N: 744369). Locate AUTO NTRL RLY, terminal
strip GNDBRR, breaker F2TR and connector NODE 15-J2. Refer to the diagram in Figure 5 and schematic in
Figure 6a (SR-2215/2216) and 6b (SR-2230).
9. Insert the appropriate end of wire 99TR51AT into relay AUTO NTRL RLY-86 and the other end into connector
Node 15-J2 cavity 10.
10. Insert the appropriate end of wire 99TR51AR to breaker F2TR and insert the other end into connector Node
15-J2 cavity 9.
11. Insert the appropriate end of wire 99TR51AU into relay AUTO NTRL RLY-85 and connect the other end to
