Low-Noise Fan (Option M65); Customer-Specific Door Stop For Control Cabinets (Option M76); Line-Side Surge Arresters (Option N54); Machine-Side Surge Arresters (Option N56) - Siemens SINAMICS GL150 Operating Instructions & Installation Instructions

Description
3.5 Options
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, surge arresters without spark gap 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, surge arresters without spark gap are used to limit
the overvoltages. They are connected between the phases in a star configuration.
3.5.20

Line-side fuses (option N58)

The fuses are used for semiconductor protection. They disconnect short-circuit currents that
can destroy semiconductors.

Cabinet lighting in the power unit (option N86)

The power unit is equipped with cabinet lighting. The lighting is switched on using a motion
detector.
