Replacement Procedure
NOTE:
In the following steps, the top and bottom batteries are referred to assum-
ing a table-mount for the robot, and the orientation is as shown in the figures.

Always leave at least two batteries connected at all times. Failure to do
so may lose the encoder positional data, requiring factory recalibration.
1. Obtain a replacement battery pack, P/N 06126-000.

2. Switch off the SmartController EX, if present.
3. Leave the 24 VDC input supply to the eMB-40R on.
4. Switch off the 200/240 VAC input supply to the eMB-40R.
5. Leave the 24 VDC supply cable from the eMB-40R +24 VDC input connector on. See
Connectors on eMB-40R Interface Panel on page 28 for locations of connectors.
IMPORTANT:
DC power must be supplied to eMB-40R, otherwise
encoder data could be lost.
6. Disconnect the 200/240 VAC supply cable from the eMB-40R AC input connector.
