Before connecting the batteries, pull out one rectifier module.
Using a digital volt meter, check for correct polarity and test the battery connection between the negative and
positive battery leads:
a.
Place the red voltmeter lead on the red negative (-) battery lead.
b.
Place the black voltmeter lead on the black positive (+) battery lead.
c.
Verify that the voltmeter reads between -46 and -54 VDC.
d.
Measure the voltage difference between the power system and the battery string. The voltage difference
should be less than 3V. If the voltage difference is greater than 3V, check for connection integrity, replace
bad battery cell as applicable, and retest the voltage. Reconnect the battery power cables to the power
supply
leads.
Install the protective covers (manufacturer-supplied) over the battery terminals.
Connect the string of batteries to the power system by plugging the battery string and the rectifier system out
-
put Anderson connectors together.
Re-install the rectifier module removed in step 8.
Verify that the cabinet heat exchanger fans are running (if the temperature is high enough).
At the AC load center, do the following:
a.
Set the Main breaker to OFF. The heat exchanger fans should continue to run.
b.
Set the Main breaker to ON and verify that power restores to the Alpha shelf.
Slide the battery string into the battery tray.
Replace the battery compartment door.
