Procedure
Equalization Procedure
Step Action
1 Remove the battery string pilot fuse.
2 Remove the battery string power fuse.
3 Ensure converter is switched Off and set to desired time
interval (12/24 hours).
4 Install converter.
5 Insert the equalize cable into the battery string fuse block
that was vacated in Step 1.
6 Turn the converter On and adjust the output voltage.
DANGER
High voltage during equalize mode.
7 Verify that the voltage being applied to the battery string
reaches the desired value. When the voltage is first applied
to the battery the converter will usually go into current
limit, and the current limit setting will regulate the voltage.
Once the charge on the battery string has increased to where
the converter is no longer in current limit, the voltage can
be verified using a DVM at the points indicated in Figure
6-1.
