charge should be connected to the rest of the plant during this
procedure. One rectifier should be sufficient to supply the
charge. However, the high voltage shutdown levels must be
raised to accomplish the initial charge. The following procedure
describes how to raise the high voltage shutdown levels.
1. Set the ac supply and rectifier controls as shown in Table
5-C.
2. Move the straps provided for options “Q” and “T” (P15
and P16) on the CM1 option board from normal position
to charge position as shown in Figure 6-2.
3. At the ac service panel supplying power to the rectifier,
insert the input fuses assigned to the rectifier or turn the
circuit breaker On.
4. Close the rectifier door and turn the POWER switch On.
The green POWER LED must light. (If not, do not attempt
to turn On the circuit breaker. Troubleshoot the problem as
described in Section 7.) Wait 10 seconds.
