Jumper: Potential equalization between different systems and earth ground (shield) for
the bus systems.
Jumper: Equalization of potential between different systems and earth ground (shield).
18 Lithium battery for buffering of static RAM and real time clock (RTC). The battery life
is estimated at 10 years, nevertheless an error message is generated if the voltage
sinks below a preset minimum level.
NOTICE: In order to avoid an error message caused by an earlier voltage drop we
suggest to replace the battery every 8 years. Spare part: VARTA CR 2032 PCB.
