Operation
WARNING
¾ MICROMASTERS operate at high voltages.
¾ When operating electrical devices, it is impossible to avoid applying
hazardous voltages to certain parts of the equipment.
¾ 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.
Certain parameter settings may cause the inverter to restart automatically
after an input power failure (e.g. automatic restart).
¾ 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.).
¾ Motor parameters must be accurately configured for motor overload protection
to operate correctly.
¾ This equipment is capable of providing internal motor overload protection in
accordance with UL508C section 42. Refer to P0610 and P0335, i
2
t is ON by
default. Motor overload protection can also be provided using an external PTC
or KTY84.
¾ This equipment is suitable for use in a circuit capable of delivering not more
than 10,000 (Frame Sizes A to C) or 42,000 (Frame Sizes D to GX)
symmetrical amperes (rms), for a maximum voltage of 230 V / 460 V / 575 V
when protected by an H, J or K type fuse, a circuit breaker or self-protected
combination motor controller (for more details see Appendix F).
¾ This equipment must not be used as an ‘emergency stop mechanism’ (see EN
60204, 9.2.5.4)
Repair
WARNING
¾ Repairs on equipment may only be carried out by Siemens Service, by repair
centers authorized by Siemens or by authorized personnel who are
thoroughly acquainted with all the warnings and operating procedures
contained in this manual.
¾ Any defective parts or components must be replaced using parts contained in
the relevant spare parts list.
¾ Disconnect the power supply before opening the equipment for access.
Dismantling & Disposal
CAUTION
¾ The inverter’s packaging is re-usable. Retain the packaging for future use.
¾ Easy-to-release screw and snap connectors allow you to break the unit down
into its component parts. You can then re-cycle these component parts,
dispose of them in accordance with local requirements or return them to
the manufacturer.
