Signal And Control Cable (Max. 2.5 Mm²) (Option M33); Connection Of Auxiliary Voltage And Signal Cable From Above (Option M34); Brass Cable Entry For Power And Signal Cables (Option M36); Degree Of Protection Ip44 (Option M44) - Siemens SINAMICS PERFECT HARMONY GH150 Operating Instructions & Installation Instructions

Description
3.9 Options
3.9.21 Signal and control cable (max. 2.5 mm²) (option M33)
Signal and control cables are connected directly to the terminals on Terminal Module TM31 or
TM15 as standard.
With option M33, you can connect signal and control cables with connection cross-sections of
up to 2.5 mm
3.9.22

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.
3.9.23

Brass cable entry for power and signal cables (option M36)

With this option, the cable entry is manufactured out of brass.
3.9.24

Degree of protection IP44 (option M44)

The degree of protection of the power section is increased from IP43 to IP44. The internal
losses are dissipated by a closed cooling circuit with air-water heat exchanger into the water.
3.9.25

Redundant fan (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 electronic monitoring of the fan.
The redundant fan is connected 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.
3.9.26

Power cable connection at the drive output from above (option M78)

The motor-side power cables can be introduced into the cabinet from the top.
3.9.27

Controlled outgoing circuit for motor fan 3-phase 400 VAC (option N30)

This option includes a controlled outgoing feeder for external auxiliaries (3-phase 400 VAC,
50 Hz, 5.3 to 20.9 kW). The controlled outgoing feeder is protected by a circuit breaker. The
circuit breaker setting range is cos φ = 0.85 (8 A to 32 A).
The option can be used to operate external fans on motors and pumps and oil supply units. The
"ON" command at the drive closes the contactor. The "OFF" command opens the contactor.
