5.5.10.6 Replacement of Backup Power Supply
You can replace Backup Power Supply SB510 and SB511 on-line, but not during a mains
supply interruption while the battery is used.
Some system functionality provided by the backup power supply is essential to a safe controller
operation. This claim for a very short replacement time. Lost functions during the absence of
backup power supply are:
• Backup supply voltage of RAM.
• Power fail detection which ensure a safe controller shut down in the event of mains supply
interruption.
• Supervision of the 24 V supply A/B for the controller subrack.
System messages is sent and spurious alarm indications is obtained in the node system
status display.
1. The replacement is made on line. That is with the mains supply on. The controller
operation is not disturbed.
2. Disconnect the supply connector on module front.
3. Grip the unit firmly and extract it quickly and decisively.
Use both handles.
4. Check that the new unit can replace the old:
– Check for lowest revision approved variant to be used for the equipment and use
replacement of the same or higher revision number.
5. Insert the new unit carefully without reaching the rear plane contacts.
Ensure that the unit slides in the guides in the subrack.
6. Push in the new unit quickly and decisively.
7. Ensure that the unit contacts mate properly with the contacts in the rear plane.
Fasten the screws in the handles.
8. Connect the power supply on module front.
9. Check the LED indications. F, BF should be OFF while IP should be ON.
The LED FC (Fast Charging) is ON.
10. Store extracted unit in envelope of conductive plastic.
5.5.10.7 Battery Exchange
The battery should be replaced at any fault indicated by the backup power supply diagnostics
and regularly (see Section 5.2.6, Backup Batteries).
1. The replacement of the Battery Unit SB522 is made on line. That is with the mains supply
on. The controller operation is not disturbed.
2. Disconnect the pluggable connector.
3. Unscrew the two fixing screws and remove the battery.
4. Install the new unit in the reverse order. Tighten the fixing screws firmly.
