Description Symbol Unit Value
Derating vs. ambient temperature:
The performance data are reduced by the
factor F
Ta
in the ambient temperature range
T
a_work_red
:
F
Ta
= 1 - [(T
a
- 40) × f
Ta
]
Example: With an ambient temperature
T
a
= 50 °C and a capacity utilization factor
f
Ta
= 3 %/K, the rated power is reduced to
P
DC_cont_red
= P
DC_cont
× F
Ta
=
P
DC_cont
× (1 - [(50 - 40) × 0.03]) = P
DC_cont
× 0.7
Operation at ambient temperatures outside of
T
a_work
and T
a_work_red
is not allowed!

Derating vs. installation altitude:
At an installation altitude h > h
nenn
, the available
performance data are reduced by the factor f.
At an installation altitude in the range
h
max_ohne
to h
max
, an isolating transformer has to
be installed at the drive system mains
connection.
Operation above h
max
is not allowed!
