4.5.2.3.2 Primary power source. When a primary power input of 18 VDC to
30 VDC is required for tests, the regulated power supply specified In 4.5.3
shall be connected to the panel assembly as indicated in 3.5.1. The automatic
DC digital voltmeter shall be utilized for the verification of the output
voltage when the power supply is adjusted from 18 VDC to 30 VDC.
4.5.2.3.3 Emergency primary power source. When a primary power input of
6.0 VDC is required for tests, the regulated power supply specified in 4.5.3
shall be connected to the panel assembly as indicated in 3.5.2. The automatic
DC digital voltmeter shall be utilized for the verification of the output
voltage.
4.5.3 Test equipment. In conduction with 4.5.2.2 the following standard
test equipment shall be utilized in the performance of the applicable tests as
specified in 4.6.

4.6 Test methods and procedures.
4.6.1 Shock. The panel assembly shall be shocked in accordance with
Procedure 11 of MIL-F-13926 except, the number of impact shocks and minimum
shock pulse (g's) shall be as specified in 3.4.2. The shock pulses (a series
of 6 total) shall be applied, 1 shock to each of the 6 surfaces of the panel
assembly. At the conclusion of the shock test the panel assembly shall be
subjected to the visual, tactile, and the audible examination of 4.6.4.1. The
panel assembly shall conform to the requirements of 3.4.2. Upon successful
completion of this examination, the panel assembly shall be subjected to the
tests specified in 4.6.2 through 4.6.5.11 Inclusive.
