Table 2-12: Apply DC Power to BTS Frame
Step Action
6
Confirm that the MAP AMP display continues to indicate between 20 and 60 amps during power
application.
NOTE
No battery charging or heavy RF loading is present at this point.
7
If the frame is equipped with back–up batteries, close (push in) the battery shelf circuit breakers
(NO TAG) for connected batteries only. This process should be completed quickly to avoid excess
charge current draw by individual battery strings.
NOTE
If the batteries are sufficiently discharged, the battery circuit breakers may not engage individually
because of surge current. If this condition occurs, disconnect the batteries from the 27Vdc bus by
setting the MAP power switch to OFF, and then engage all the connected battery circuit breakers. The
MAP power switch should then be turned ON.
