Procedure For Changing The Battery - ABB CP1484 Manual

Procedure for changing the battery

1) Touch the mounting rail or ground connection (not the power supply!) in order to discharge
any electrostatic charge from your body.
2) Remove the cover for the lithium battery. To do this, slide the cover down from the CPU.

3) Remove the battery from the holder (do not use pliers or uninsulated tweezers -> risk of short
circuiting). The battery should not be held by its edges. Insulated tweezers may also be
used for removing the battery.
