A back-up battery can be installed in the power supply to save configured
values during a power failure (using function block SAV) (nominal voltage,
approx. 3.6 V).
Current load: approx. 10 µA depending on the particular CPU module
It is recommended that the battery is changed every year.
When removing the power supply (the defect, changing the fan) back-up is
no longer possible. If required, the back-up voltage must be provided
through the appropriate contact of the backplane connector.
Lithium battery 3,4 V, 5 Ah
Design C (Baby element)
The monitoring CPU module identifies if there is no back-up battery or if the
back-up battery is discharged (at slot 1; flashing "B").
The battery should be changed with the subrack powered-up to prevent data
loss. If a supply voltage is not available, then a voltage must be applied via
connector X3!
For safety reasons, it is not permissible that lithium batteries are in the
equipment when it is transported unless the battery manufacturer
permits this expressly using an appropriate declaration.
 When the equipment is stored and shipped, the batteries must be
individually and separately packed in a non-conductive material.
 There is a danger of explosion if they are not correctly handled. We
can accept no liability for incorrectly handled batteries.
 Used batteries must be disposed of in compliance with national and
European legislation and regulations.
 The lithium batteries must be removed from the battery holder
before the subrack or power supply is disposed of.
