Securing Contactors
If Battery and Load contactors are in the system, contactor control boards
should be configured so that they do not OPEN during the controller
replacement. To ensure that these contactors do not open, force all LVLD
and LVBD contactors closed.
NOTE: These contactors may have already been forced closed per
customer requirements. If so, then proceed to the next step.
To force LVLD contactors closed, place SW300 in the up position as
shown in figure 6-2 and 6-3.
