Lock Barrel (Option M40); Degree Of Protection Ip41 (Option M41); Separate Installation (M49); Low-Noise Fan (Option M65) - Siemens SINAMICS GL150 Operating And Installation Instructions

3.5.13

Lock barrel (option M40)

The cabinet interlocking is equipped with locking cylinders. All cabinets in the plant must have
the same locking cylinder.
3.5.14

Degree of protection IP41 (option M41)

The degree of protection is increased to IP41.
3.5.15

Separate installation (M49)

The maximum cable length between the open-loop control cabinet and the power unit of the
starting converter is 70 m. The cables to connect the starting converter with the excitation
equipment are not included in the scope of supply of the compact system. The DRIVE-CLiQ
connection is an exception. This is included in the scope of supply for the starting converter.
3.5.16

Low-noise fan (option M65)

Sound pressure is minimized compared to standard setup through the use of special fans.
3.5.17

Customer-specific door stop for control cabinets (option M76)

The customer-specific door stop for the control cabinets ensures that the safety regulations
are complied with – for example escape and evacuation routes.
3.5.18

Line-side surge arresters (option N54)

The surge arrester limits voltage peaks on the line side and prevents overvoltages.
Overvoltages can occur when inductive loads are switched, for example when a transformer
is switched off when it has no load connected to its secondary These overvoltages can pose
a danger to the converter. For indoor systems, spark-gap-free surge suppressors made of
metal oxide are used to limit the overvoltages. They are connected between the phases in a
star configuration.
3.5.19

Machine-side surge arresters (option N56)

The surge arrester limits voltage peaks on the motor side and prevents overvoltages.
Overvoltages can occur when inductive loads are switched, for example when a transformer
is switched off when it has no load connected to its secondary These overvoltages can pose
a danger to the converter. For indoor systems, spark-gap-free surge suppressors made of
metal oxide are used to limit the overvoltages. They are connected between the phases in a
star configuration.
