Replace the Battery
Replace the back-up battery every four years.
1. Remove the lid on the
power-supply battery
compartment by removing the
two screws.
2. Use a screwdriver to remove the
battery from its compartment.
3. Insert a new battery.
4. Dispose of the old battery in accordance with local regulations.
ATTENTION
Make sure that the GuardPLC 2000 power supply has power applied. Replacing the
back-up battery while the controller is de-energized causes a reset. All data including the
clock settings will be lost.
A risk of fire and chemical burn exists if the battery is not handled properly. Do not crush,
puncture, disassemble, or short external contacts, or expose the battery to temperatures
higher then 60
°C (140 °F).
IMPORTANT
Follow the polarity shown on the battery compartment. Make sure that the
contact pins inside the compartment are not damaged.
ATTENTION
Do not incinerate or dispose of lithium batteries in general trash collection. They
