If the BIC needs to be replaced, the rectifiers will continue to operate
and the system will stay online. The only potential problem occurs when
LVLD or LVBD contactors are present in the system. To ensure that
these contactors do not open during the BIC replacement, force all
LVLD and LVBD contactors closed.
• Place switch SW300 on the EBV Board in the up position as
shown in Figure 8-13 to force all LVLD contactors closed.
• Place switch SW300 on the BJN Board in the down position as
shown in Figure 11-5 for full-height cabinets to force LVBD
contactors closed.
• Place switch SW300 on the BJN Board in the up position as
shown in Figure 11-6 for half-height cabinets to force LVBD
contactors closed.
Once this is accomplished, the BIC may be removed. Remove the two
screws holding BIC to the terminal board, then lift the BIC off of the
terminal board.
