7.5 Mains connection
Select a country-specific power plug and insert it in the power unit.
Check, whether the voltage acceptance on the scales is set correctly.
Do not connect the scales to the power grid unless the information on
the scales (sticker) matches the local mains voltage.
Only use KERN original mains adapter. Using other makes requires
consent by KERN.
Important:

Before starting your weighing balance, check the mains cable for
damage.

Ensure that the power unit does not come into contact with liquids.

Ensure access to power plug at all times.
In order to obtain exact results with the electronic balances, your balance
must have reached the operating temperature (see warming up time chap. 1).
During this warming up time the balance must be connected to the power
supply (mains, accumulator or battery).
The accuracy of the balance depends on the local acceleration of gravity.
Strictly observe hints in chapter Adjustment.
