MICROMASTER 411 & COMBIMASTER 411 Operating Instructions
62 6SE6400-5CA00-0BP0
WARNING
When operating electrical devices, it is impossible to avoid applying hazardous
voltages to certain parts of the equipment.
Emergency Stop facilities according to EN 60204 IEC 204 (VDE 0113) must
remain functional in all operating modes of the control equipment. Any
disengagement of the Emergency Stop facility must not lead to uncontrolled or
undefined restarts.
Faults occurring in the control equipment can lead to substantial material
damage, or even grievous bodily injury (i.e. potentially dangerous faults).
Additional external precautions must be taken, or facilities provided, to ensure
safe operation, (e.g. independent limit switches, mechanical interlocks, etc.).
COMBIMASTER 411/MICROMASTER 411 operate at high voltages.
Certain parameter settings may cause the inverter to restart automatically after
an input power failure.
This equipment is capable of providing internal motor overload protection.
Refer to P0610 (level 3) and P0335. I
2 t is ON by default. Motor overload
protection can also be provided using an external PTC via a digital input.
This equipment is suitable for use in a circuit capable of delivering not more
than 10,000 symmetrical amperes (rms), for a maximum voltage of 460 V
when protected by a H or K Class fuse (see Table 7-6).
This equipment must not be used as an ‘Emergency Stop mechanism’ (see
EN 60204, 9.2.5.4)
4.1 Frequency Setpoint
