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.
