0 Check the battery
voltage •Battery voltage should be in 21-27.6 Vdc - - •If battery voltage is less than 21 Vdc, the DRU
module will not operate
in buffering mode.
•Battery voltage 19.2 Vdc min will
enable “Repl. BAT.” relay contact.
(DRU module will not charge the
battery)
- - •Change the battery if
the voltage is less than
19.2 Vdc.

Re-check battery polarity
and connection make
corrections.
Re-check battery voltage
and replace with a new
battery (21-27.6 Vdc).

•Re-check battery
wiring and compare
with “Typical
Application Notes” in
DRU module
datasheet. Make
corrections as needed.
•Re-check battery
