6 LIMITS OF USE
OPDE DC-DC has to be installed inside an electrical panel, which can also not be conditioned. In this case, the
environmental limits of use are given below.

The air pressure limits correspond to an operating field of 02000m a.s.l. In fact, over
1000 m above sea level, it is necessary to derate the rated current of the converter by 1%
per 100 m.
(2)
The converter must be installed inside an electrical panel and, therefore, not outdoor.
