With option M32, you can connect signal and control cables with connection cross-sections of
up to 2.5 mm
2
to a terminal strip via cage clamp terminals.
3.6.21 IP54 degree of protection (option M54)
This option increases the degree of protection of the drive from IP43 to IP54.
3.6.22 Redundant fan in the power unit (option M61)
To increase the plant availability, an additional redundant fan is installed. The differential
pressure sensing function in the cabinet immediately identifies if a fan in the cabinet fails. The
open-loop control system switches on the redundant fan so that the drive system does not fail.
This prevents production failures or interruptions. The replacement of the defective fan can be
postponed to the next planned stoppage.
3.6.23 Suitability for marine use (option M66)
The converter design corresponds to the requirements of the following classification societies.
● Lloyds Register
● American Bureau of Shipping
● Germanischer Lloyd
● Bureau Veritas
● Det Norske Veritas
● Chinese Classification Society
The converter has the following supplementary equipment:
● Salt water resistant paint
● Strengthened mechanical cabinet design
● Handrail below the operator panel
● Mechanical cabinet door locking
● IP44 degree of protection
● Anti-condensation heating
The converter can be welded to the ship's hull plate
3.6.24 Capacitor Modules to increase the DC-link capacitance (option N08)
The N08 option is used to increase the surge-current increase for the switching-frequency
reduction. For this purpose, the DC-link capacitance of the drive is increased by 18 mF.
