4. Remove the dummy connector cap from the battery board. See the following figure.
NOTE: Newer robots (which includes those with an eCS-ECAT) have
PCAs with only three battery connections, therefore, they do not have
dummy connectors. For those robots, remove and replace all three bat-
teries one at a time. This is the reason that 24 VDC must be left on for this
procedure.
5. Connect a new battery (1st one) to the pin from which you disconnected the dummy
connector cap in the previous step. See the following figure.
