This chapter describes service/maintenance work that can be carried out by a qualified end user.
1 Changing the battery
The lithium battery buffers the internal real-time clock (RTC) and CMOS data.
Information:
•
The product design allows the battery to be changed with the B&R device switched either on or
off. In some countries, safety regulations do not allow batteries to be changed while the module
is switched on.
•
Any BIOS settings that have been made will remain when the battery is changed with the power
turned off (stored in non-volatile EEPROM). The date and time must be reset later since this
data is lost when the battery is changed.
•
The battery should only be changed by qualified personnel.
Warning!
The battery must be replaced by a Type CR2477N Renata battery only. The use of another battery may
present a risk of fire or explosion.
The battery may explode if handled improperly. Do not recharge, disassemble or dispose of in fire.
The following replacement lithium batteries are available: 4A0006.00-000 (1 pc.) and 0AC201.91 (4 pcs.).
