IV: Combination of xStart components with DS7-FAN-032 device fan
In this case, the standard values can be achieved (compare with I).
V. Combination of xStart components with DS7-FAN-032 device fan
and higher starting frequencies
If higher starting frequencies are required, the overload curves of the
DS7-34xSX007 soft starter apply.
① At T
x
= 5 s the permissible overcurrent factor is reduced to around X = 2.2
(I
RLP
= 20 A) at a maximum of 40 starts per hour.
② I
RLP
= 27 A: At T
x
= 5 s and X = 3 a maximum of four starts per hour are
permissible here.
￫
The overload curves of the individual DS7 soft starter variants
are listed in the Appendix on page 219.
