HMI battery change procedure:

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 nonvolatile EEPROM). The date and time must be reset later since this data is lost when the battery is changed.

• The battery should only be replaced by qualified personnel

Warning!

 The battery is only permitted to be replaced by a Renata CR2477N battery. 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.

SG360-ISM-004 | REV F

Opening the Covers:

1. Power down the unit and follow all lockout tag out procedures.

2. Using an insulated screwdriver, depress latching tab on inside of covers.

DANGER: Power system down and lock out power panel prior to opening the covers. Failure to comply may result in injury or death!

SG360-ISM-004 | REV F

3. While holding in on latching tab press up on covers to release.
