Repeat this procedure for each additional rectifier. When complete,
verify the plant charge bus is within tolerance and make final
adjustments if necessary.
Warning: Verify that only one wire is terminated on TB2 pins 1 and 2
on the controller. If other wires exist, determine what the leads are
feeding and their function. They may have to be jumpered around before
removing from TB2 or loss of loads may occur. Plants equipped with
ED83018-31GRP 17 low voltage disconnect panels are at risk.
1. Remove, mark or tag and insulate all external wires (office alarms)
terminated on TB1. See Figure 3-6.
2. Use Table 3-I to record wire colors.
Note: Galaxy Controller alarm connections do not require crimped
connections. If desired, cut the existing MCS alarm connections.
Leave adequate length for re-termination to the Galaxy Controller.
