m

Grease or dirt on the contact surfaces 
form a transfer resistance that will 
shorten the life of the battery. Only touch 
the battery at the edges.

Make sure that the correct type of battery 
is used and observe correct polarity when 
changing it.

If the battery capacity that is displayed by the GridVis 
software is in the "Undervoltage" range, we recommend 
changing the battery.

If the capacity of the battery is too low and a time 
synchronisation via NTP is not set, the device software 
takes the last valid time stamp and resumes it.

The battery is replaced via the battery insert provided on 
the front of the device. Ensure that the correct type of 
battery is used here and observe correct polarity when 
changing it. Information about polarity is provided on 
the battery insert cover.

Procedure
1.  To change the battery, the device must be switched off.
2.  Discharge any electrostatic charge in your body, e.g. 

by touching an earthed cabinet or metal part (radiator) 
connected to the earth of the building.

3.  Open the battery compartment on the front of 

the device.

4.  Remove the battery from the battery compartment, 

e.g. using long-nose pliers.

5.  Ensure that the polarity is as shown on the battery 

compartment and slide the replacement battery into 
the battery compartment. Use a battery compliant 
with the description in the technical data for this. 
The battery must fulfil the safety requirements of 
UL1642. Otherwise, there is a risk of combustion or 
explosion.

6.  Close the battery compartment with the relevant 

cover.

7.  Dispose of the old battery according to the legal 

regulations.
