A2. RTC battery change
In the WIB8000 module a CR2032 type battery serves to provide power for the real time clock, when the WIB
is de-energized. You can activate this battery by the jumper J1. When the jumper is removed the battery is not
connected. Disconnecting the battery could be reasonable for an intermediate storage to save the battery
capacity. This jumper is not set at delivery.
Jumper J1 for battery
connection
A battery change is necessary, when you notice that the date adjusted in menu "Web interface/time" resets to
year 2004.
For changing the battery turn the metal clip, which fixes the battery, to the front side of the WIB. The lithium
cell can be drawn out of the socket. When installing the new lithium cell take care of the right polarity.
