3.8.37 Connection of auxiliary voltage and signal cable from above (option M34)
This option makes it possible to bring the cables for the auxiliary voltage and signal cables into
the cabinet from the top.
3.8.38 Brass cable entry for power and signal cables (option M36)
With this option, the cable entry is manufactured out of brass.
3.8.39 Stainless steel cable entry for the power cable (option M37)
With this option, the cable entry for the power cables is made of stainless steel.
3.8.40 IP42 degree of protection (option M42)
The degree of protection is IP42. Only for drives with fan.
3.8.41 IP54 degree of protection (option M54)
The degree of protection is IP54. Only for drives with air-air or air-water heat exchangers.
The air-air heat exchanger degree of protection is IP4x.
3.8.42 Arcing fault strength (option M57)
Option M57 is available on request.
A technical check is required on an order-for-order basis. Mechanical design changes may be
required. A technical LoA is required to check the earliest possible delivery time.
The drive corresponds to IEC 62271-200 with internal arc classification IAC AFLR 25 kA 0.5 s.
The designation for the arc classification is described as follows in IEC 62271-200 (definition in
IEC 62271-200, see below).
● IAC AFLR
● Arc fault current 25 kA
● Arc fault duration 0.5 s
● Designation: IAC AFLR 25 kA, 0.5 s
The internal arc classification data specified for the product (IAC) are intended for system
integrators to limit the available short-circuit current and short-circuit tripping time of the main
power supply to a value below the above-mentioned IAC data. This is generally realized using
a current-limiting inductance or a transformer (uK) and a time-limiting main breaker
(discrimination).
