Connection of the Uninterruptibe Power Supply

Mounting the UPS

The battery, with which RAM and clock are buffered, has a limited service
life (see chapter "Wear parts" starting on page 4-4).
This lithium battery may not be changed by the user. The battery may only
be exchanged by the Bosch Rexroth Service (see chapter "Service &
Support") or by personnel specially trained and authorized by the Service.
The accessories of Bosch Rexroth include uninterruptible power supplies
(UPS) for the 230 V supply as well as for the 24 V supply (see section
"Accessories" on page 10-2).
These UPS units are able to override brief voltage breakdowns. In case of
longer voltage breakdowns, they initiate and facilitate a proper powering
down of the operating system. Therefore, Bosch Rexroth recommends to
use an UPS.
The uninterruptible power supply is connected to the voltage supply line
and communicates with the VSB 40.1 via the COM interface XCOM.

To mount the UPS for 230 V, a holder is available as accessories. This
holder can be engaged in a top-hat rail or can be fastened to a rear panel
with two M6 screws.
After mounting the holder, lift the angle bracket and insert the UPS. Now,
close the angle bracket and fix it with the enclosed nut.
