Technical Characteristics - Nice PS224 Instructions And Warnings For The Fitter

4) Maintenance, Storage Battery Replacement, Disposal
GB
The PS224 buffer battery does not require any maintenance; how-
ever, in case of long periods of inactivity, it should be disconnected
from the system and stored in a dry location.
Storage batteries should be replaced whenever their autonomy is
significantly reduced as a result of aging. This operation may only be
performed by qualified technicians; please contact NICE customer
service.
!
WARNING: storage batteries contain lead and other
polluting substances; certain electronic components may
contain polluting substances: do not dispose of them with
other common waste. Use the disposal methods estab-
lished by the regulations locally in force.

5) Technical Characteristics

Nice S.p.a., in order to improve its products, reserves the right to modify their technical characteristics at any time without prior notice. In
any case, the manufacturer guarantees their functionality and fitness for the intended purposes.
Note: all the technical characteristics refer to a temperature of 20°C.
Note: the performances of lead-acid storage batteries are affected by their operating conditions: temperature, absorbed current, state of
charge and age of the storage battery may cause significant variations in the data shown below.
