Warnings
♦ 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.).
♦ MICROMASTERS 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 in
accordance with UL508C section 42. 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 230/460V when
protected by a time delay fuse (see Table on page 102)
♦ This equipment must not be used as an ‘emergency stop mechanism’ (see EN
60204, 9.2.5.4)
