20.
NOTE:
To measure the battery string voltage accurately, disconnect any battery
strings other than battery string being measured. [To disconnect other
battery strings, unplug the battery string cable connector marked STR
from the battery cable connector marked STR( ).]
On control & distribution panel, connect DMM to BAT( ) (1, 2, 3 or 4) test point
and PVR test point for battery string being installed.
21. Does meter indicate battery string voltage of 50.4 V DC or higher?
If YES, then proceed to Step 21.
If NO, then continue with Step 20.
22. Visually inspect cable assembly between control & distribution panel and bat-
tery string. Replace cable assembly fuse and/or cable assembly until meter
indicates correct voltage.
23. Is this the last battery string to be installed?
If YES, then proceed to Step 22.
If NO, then repeat from Step 1 for next battery string to be installed.
24. Disconnect test equipment. Reconnect any battery strings disconnected for
voltage measurement. Close and lock battery compartment door.
25. Between one and three hours after the rectifiers are installed, measure the
voltage of each battery in the string and record on form 1285 supplied with the
batteries. Meter should indicate between 4.44 V DC and 4.64 V DC for each
battery. Any battery outside this limit should be measured again within one
week. If it is still outside the limit, replace battery.
STOP. YOU HAVE COMPLETED THIS PROCEDURE.
