Procedure
Step 1
Using a voltmeter, verify the office battery and ground at the following points on the fuse panel:
a) To verify the power, place the black test lead of the voltmeter to the frame ground. Place the red test lead
on the A-side connection and verify that it is between –40.5 VDC and –57.6 VDC. Place the red test lead
on the B-side connection and verify that it is between –40.5 VDC and –57.6 VDC.
Note
The voltages –40.5 VDC and –57.6 VDC are, respectively, the minimum and maximum voltages
required to power the chassis. The nominal steady state voltage is -48 VDC.
