The hard disk to be installed must already be provided with an in‐
stalled operating system. In any case, it is recommended to have a
completely installed operating system on the hard disk, to shorten
the installation time!
1.
Save all required user data as well as the operating system settings of
your system on an external storage medium or via the network connection!
2.
Shut down the PC.
3.
Disconnect the power supply.
4.
Open the right door on the rear side of the VPP 21.
5.
Remove the hard disk.
6.
Insert the new hard disk.
7.
The new hard disk parameters are automatically recognized by the sys‐
tem. If the operating system does not boot, interrupt the power supply for
at least 10 seconds and restart.
8.
After properly booting the PC the user data and the operating system set‐
tings for the normal operating mode have to be restored.

Display
A fading backlight causes a progressive deterioration of the LCD display's
readability, so that a display exchange is necessary. Exchanging the backlight
is not possible. To exchange the display, please contact the Bosch Rexroth
Service.
8.4
Buffer Battery
The build-in lithium battery buffers the SRAM modules and the clock, if the
power supply (24 VDC) is switched off. The buffer time is at least five years, so
that after five years a battery exchange might occur. To avoid the loss of data
during battery exchange, a gold capacitor provides for the buffering (10 mi‐
nutes).
The battery is permanently checked by a monitoring circuit. If the voltage falls
below its minimum value, LED H4 at the connector panel is activated. Then,
you should exchange the battery. For this, please contact the Bosch Rexroth
service.
If you decide that the battery should be exchanged by your own skilled staff,
consider the following instructions:
DANGER
Fire or explosion hazard by use of wrong battery types!
Replace the battery only by a type for the VPP 21 permitted by Bosch Rexroth.
This is currently: Lithium battery 3.0 V; 2.3 Ah with Bosch Rexroth part number
1070922650.
DANGER
Risk of injury through improper treatment of the battery!
The battery in this device can cause fire or chemical burn, if it is treated
in the wrong way.
The battery must not be charged, opened, heated over 100 °C and burn.
The lithium element is designed for the use under normal temper‐
ature conditions. The temperatures to be expected must not exceed
values of 212.00 °F.
