Storage
21.
The device and its replacement modules must stored temperature -between -25°C
to +65°C.
. This should also done before the device commis-
sioned.
Before voltage applied the device for the first time, should left the operating
environment for least two hours equalise the temperature and prevent the creation of
humidity and condensation.
It also recommended connect the device the auxiliary voltage every two years to
condition the electrolytic capacitors.
The relative humidity may not result the creation condensation ice.
It recommended limit the storage temperature -10 +55 prevent the elec-
trolytic capacitors from ageing prematurely. extreme climatic conditions (in the tropics), this also 'preheats' the device and
prevents condensation. Storage
The devices and spare components must stored rooms that are dry and clean
