Changing the lithium metal battery
The battery must be changed depending on the self-diagnosis of the WPM device.
The values can be checked using the WPM configuration software and can be called up using
status information in the Gateway.
To loosen the battery plug, the locking catch on the plug connector needs to be unlocked. This
can be done using the tip of a pen, and the plug must be pulled at the same time.
