¹⁾ The armature/field supply voltage can be less than the rated supply voltage armature/field (set with Parameter P078; for converters with 400 V rated voltage, input voltages of up to 85 V are permissible). The output voltage is reduced accordingly. The specified output DC voltage can be guaranteed up to undervoltages 5 % below the supply voltage (rated supply voltage armature/field).

²⁾ Values apply to output rated DC current.

³⁾ Load factor K1 (DC current) as a function of the coolant temperature (see P077 Operating Instructions, Section 11). K1 > 1 only permissible where K1 *K2 ? 1st. overall reduction factor K = K1 * K2 (for K2 see Footnote 4)

^a) In spite of derating, converters of ? 400 A with enhanced cooling may be operated at an ambient or coolant temperature of 50 ?C only if the rated supply voltage of the converter fan is safely within the limited tolerance range of 400 V +10 % -15 %.

^b) Not permissible when T400 or OP1S are used.

⁴⁾ Load values K2 as a function of the installation altitude (see P077 Operating Instructions, Section 11). Overall reduction factor K = K1 * K2 (for K1 see Footnote 3).

The supply voltages for all electric circuits are possible for site altitudes up to 5000 m with basic insulation, with the exception of converters for rated supply voltages:

⁸⁾ For UL systems, a Siemens motor protection circuit breaker Type 3RV1011-0KA1 or 3RV1011-1AA1, adjusted to 1.25 A for the fan motor Type RH28M-2DK.3F.1R must be installed in 6RA7090, 6RA7091, 6RA7093 and 6RA7095 converters with a rated voltage of 400 V or 575 V.

⁹⁾ Operation in the extended frequency range of 23 Hz to 110 Hz is possible on request.
