SRAM backup battery replacement
Only those personnel who have received approved safety and maintenance training may perform
this work.
When replacing the batteries, be careful not to touch the high–voltage circuits (marked
and
fitted with an insulating cover).
Touching the uncovered high–voltage circuits presents an extremely dangerous electric shock
hazard.
NOTE
The CNC uses batteries to preserve the contents of its memory, because it must retain data such as
programs, offsets, and parameters even while external power is not applied.
If the battery voltage drops, a low battery voltage alarm is displayed on the machine operator’s panel
or screen.
When a low battery voltage alarm is displayed, replace the batteries within a week. Otherwise, the
contents of the backupped data will be lost.
Refer to the maintenance manual or maintenance section of the operator’s manual for details of the
battery replacement procedure.
