23.1.2 Charging the rechargeable battery pack
The rechargeable battery is normally shipped in discharged condition.
Fully charge the battery prior to the initial instrument start .
NIVUS recommend charging the battery outside of the instrument by using the power adapt-
er/battery charger to ensure 100 % of charging capacity. If built in, the battery will be charged
only up to approx. 75 %.
WARNING Risk of explosion removing/inserting and charging the battery pack in Ex areas
The rechargeable battery pack shall be removed/inserted and charged only out of Ex are-
as. Never do so within Ex areas since otherwise explosion protection cannot be guaran-
teed.

no. 1; NFM0 ZLAD) (available from NIVUS GmbH at extra costs) only. Observe the specifi-
cations attached on the power adapter/battery charger.
Using inappropriate battery chargers may destroy the battery (e.g. due to leaking of battery
cells, explosion or similar).
