Electrical Firing of BA-629/U and BA-

630/U:

(a) To fire the battery, an electrical

current must be applied to pins J and K (the two centrally

located pins) of the battery connector. See figure F-3.

(b) Connect a switched power supply to

pins J and K as indicated in figure F-3. Fire the battery by

closing the switch for no more than three (3) seconds.
