Operation
WARNING
MICROMASTER 411/COMBIMASTER 411 operate at high voltages.
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 operative in all operating modes of the control equipment. Any
disengagement of the Emergency Stop facility must not lead to uncontrolled or
undefined restart.
Wherever 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 or enforce safe operation, even when a fault occurs (e.g. independent
limit switches, mechanical interlocks, etc.).
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 an H or K Class fuse (see Section 7.5).
This equipment must not be used as an ‘emergency stop mechanism’ (see EN
60204, 9.2.5.4)
