WARNING
! MICROMASTERS 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.
! Motor parameters must be accurately configured for motor overload protection
to operate correctly.
! This equipment is capable of providing internal motor overload protection in
accordance with UL508C section 42. Refer to P0610 and P0335, i
default. Motor overload protection can also be provided using an external PTC
(disabled by default P0601).
! 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 230 V / 460
V / 575 V when protected by a H or K type fuse (see Tables starting on page
109).
! This equipment must not be used as an 'emergency stop mechanism' (see EN
60204, 9.2.5.4)
CAUTION
Only qualified personnel may enter settings in the control panels. Particular
attention must be paid to safety precautions and warnings at all times.
