3.6.21 Signal and control cable (max. 2.5 mm²) (option M32)
Signal and control cables are connected directly to the terminals on Terminal Module TM31
or TM15 as standard. The maximum connectable cross-section for these cables to the TM31
and TM15 Terminal Modules is limited to 1.5 mm
2
.
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.
3.6.22 IP54 degree of protection (option M54)
This option increases the degree of protection of the drive from IP43 to IP54.
3.6.23 Redundant fan in the power unit (option M61)
To increase the plant availability, the drive can be fitted with an additional, redundant fan. If a
fan in the drive cabinet fails, this is detected immediately by the differential pressure monitor
in the cabinet. The redundant fan is switched in by the drive controller without this causing the
drive and, in turn, the drive system to fail. This prevents production failures or interruptions.
The replacement of the defective fan can be postponed to the next planned stoppage.
