5.9.1.1 Carrying out battery replacement
(1) Save the data as a precautionary measure
(
see Chapter 3.3.3
).
(2) Open up the housing cover and pull it downwards. The battery is then accessible.
F
Do not pull the battery compartment downwards too vigorously, because connected
cables may be broken.
F
Check the type and order number of the new battery.
Tip:
Mark the old batteries, e.g. with a felt-tip pen or sticker before you start the
battery replacement. This avoids any later confusion.
(3) At least one battery must always be connected to one of the two plugs. If this is not the
case, volume pulses may be lost during the battery replacement and the clock may be
slow after battery replacement.
(4) Release the cable tie to enable the battery to be removed.
(5) Insert the new battery and connect to the free plug in parallel to the old battery (both
are electrically isolated). The plugs are polarised against incorrect connection.
(6) Pull off the old battery from the plug and remove.
(7) Fix the new battery with the cable tie and insert its end into the opening in the housing.
(8) Close the device again.
F
Make sure that the connected cables are not pinched.
(9) Check in the display that no message "3" is entered under "Status"!
(10) The initial capacity must be re-entered under "Service" - "Battery capacity" (
→
3.3.3:
BAT.C
) (this is essential even with the same capacity value)! With the use of the size
"D" battery obtainable from ELSTER GmbH, the value 13.0 Ah should be entered ac-
cordingly for
BAT.C
.
(11) Check the operating life calculated by the TC210: For
BAT.R
(
→
3.3.2) at least 96
months must be displayed. Apart from that, carry out step (9) again.
This successfully concludes the battery replacement.
