Do not apply power to the shelf assembly until you complete all installation steps.
Caution
Using a voltmeter, verify the office battery and ground at the following points on the fuse and alarm
Step 1
panel:
a.
b.
Insert the fuse into the fuse position according to site practice. The fuse rating must not exceed 30A.
Step 2
At the bottom rear of the shelf assembly, remove the cover panel to access the power connections.

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 VDC. Place the red
test lead on the B-side connection and verify that it is between –40.5 VDC and –57 VDC.
The minimum and maximum voltages required to power the chassis are –40.5 VDC and
Note
–57 VDC respectively.
To verify the ground, place the black test lead of the voltmeter to the frame ground. Place the red
test lead on the A-side return ground and verify that no voltage is present. The voltmeter must read
0 VDC. Place the red test lead on the B-side return ground and verify that no voltage is present. The
voltmeter must read 0 VDC.
To verify the A-side of the shelf, place the black lead of the voltmeter to the frame ground. Place the
red test lead to the BAT1 (A-side battery connection) red cable. Verify that it reads between
–40.5 VDC and –57 VDC. Then place the red test lead of the voltmeter to the RET1 (A-side return
ground) black cable and verify that no voltage is present.
The voltages –40.5 VDC and –57 VDC are, respectively, the minimum and maximum
Note
voltages required to power the chassis.
