10.4 Mounting a power pack
If an external power supply is needed, only the power pack designed for our heat meter may be used.
To connect the power pack, first open the meter´s calculator as described above in 10.2. Then remove the battery
from the calculator and plug it into the battery connector in the power pack. Protect the power pack against
unauthorized opening using one of the numbered adhesive seals enclosed. The added bar code label can be used
for the purpose of documentation. (The battery is a backup in case of a power outage.)
The power pack cable (A) has two connectors; plug the one connector onto the contact fingers on the left hand side
of the PC board. Then feed the cable through the meter´s leftmost cable feedthrough (viewed from the front) after
removing the blind grommet. The other connector is to be plugged into the female connector on the PC board.
Only authorized technical personnel may connect the power pack to the 230 V mains supply and check it.
When the meter detects external power supply the pictogram of a mains plug appears in the display lower left.
Close the calculator.
