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.
