Siemens SINUMERIK:  Changing The Battery

Procedure

Proceed as follows to replace the dual fan/battery module but only observe points 3 and 4 if you want to replace the battery as well:

  1. Gently push the dual fan/battery module backwards (by pressing on the pressure point) to release the module from its front interlock (snap-in hooks).

2. NoticeForcibly withdrawing the module can permanently damage itNever pull the dual fan/battery module out abruptly without having released the interlock. This would break the snap-in hooks and you would not be able to reinsert the module.

3. Tilt the dual fan/battery module forward at an angle and pull out the plastic guide from the NCU cutout.

4. Remove the battery by first removing the plug connector and then taking out the battery.

5. Connect the cable plug connector of the new battery to the mating connector in the dual fan/battery module and push the battery in.

6. Tilt the dual fan/battery module forwards at an angle with the open side facing up (battery visible).

7.Push the plastic guide into the cutouts on the underside of the NCU.

8.Tilt the dual fan/battery module up until the front interlock snaps into place. The electrical connection between the dual fan/battery module and the NCU is established automatically.
