Description Symbol Unit Value
Conductive dirt contamination Not allowed
Protected the devices against conductive dirt con‐
tamination by mounting them in control cabinets of
the degree of protection IP54 (in accordance with
IEC 60529).
Degree of protection of the device (IEC 60529) IP20
Use in the scope of CSA / UL For use in NFPA 79 Applications only.

Derating vs. ambient temperature:
In the ambient temperature range T
a_work_red
, the
performance data are reduced by the factor F
Ta
:
F

= 1 - [(T

For the drive connection box KCU, the rated
power (P
out
) is reduced at the output of the 42 V
control voltage. The rated power at the output of
the power section (P
DC_cont
) is not reduced.
Example: With an ambient temperature
T
a
= 50 °C and a capacity utilization factor
f
Ta
= 2 %/K, the rated power is reduced to
P

= P
