death or serious injury.
WARNING
indicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury.
CAUTION
used with the safety alert symbol indicates a potentially hazardous situationwhich,
if not avoided, may result in minor or moderate injury.
CAUTION
used without safety alert symbol indicates a potentially hzardous situation which, if
not avoided, may result in a property demage.
NOTICE
indicates a potential situation which, if not avoided, may result in an undesireable
result or state.
NOTE
For the purpose of this documentation, "Note" indicates important information
relating to the product or highlights part of the documentation for special
attention.

Transport & Storage
WARNING
♦Correct transport, storage, erection and mounting, as well as careful
operation and maintenance are essential for proper and safe operation of the
equipment.
CAUTION
♦Protect the inverter against physical shocks and vibration during transport and
storage. Also be sure to protect it against water (rainfall) and excessive
temperatures (see table on page 92).
Commissioning
WARNING
♦Work on the device/system by unqualified personnel or failure to comply with
warnings can result in severe personal injury or serious damage to material.
Only suitably qualified personnel trained in the setup, installation,
commissioning and operation of the product should carry out work on the
device/system.
♦Only permanently-wired input power connections are allowed. This equipment
must be grounded (IEC 536 Class 1, NEC and other applicable standards).
♦If a Residual Current-operated protective Device (RCD) is to be used, it must
be an RCD type B. Machines with a three-phase power supply, fitted with
EMC filters, must not be connected to a supply via an ELCB (Earth Leakage
Circuit-Breaker - see DIN VDE 0160, section 5.5.2 and EN 50178 section
5.2.11.1).
♦The following terminals can carry dangerous voltages even if the inverter is
inoperative:
- the power supply terminals L/L1, N/L2, L3
- the motor terminals U, V, W
- and the terminals DC+/B+, DC-, B- and DC/R+
♦This equipment must not be used as an ‘emergency stop mechanism’ (see
EN 60204, 9.2.5.4)
CAUTION
The connection of power, motor and control cables to the inverter must be carried
out as shown in Figure 2-7 on page 30, to prevent inductive and capacitive
interference from affecting the correct functioning of the inverter.

Operation
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, i2t is ON by
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 460V
when protected by a H or K type fuse (see Tables starting on page 93).
♦This equipment must not be used as an ‘emergency stop mechanism’ (see
EN 60204, 9.2.5.4)
Repair
WARNING
♦Repairs on equipment may only be carried out by Siemens Service, by
repair centers authorized by Siemens or by qualified personnel who are
thoroughly acquainted with all the warnings and operating procedures
contained in this manual.
♦Any defective parts or components must be replaced using parts contained in
the relevant spare parts list.
♦Disconnect the power supply across all poles before opening the equipment
for access
Dismantling & Disposal
CAUTION
♦The inverter’s packaging is re-usable. Retain the packaging for future use or
return it to the manufacturer.
♦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.

1.1 The MICROMASTER 430
The MICROMASTER 430s are a range of 3AC-frequency inverters for controlling
the speed of three phase AC motors. The various models available range from the
7,5 kW input to the 90 kW input.
The MICROMASTER 430 is especially well suited for use with pumps and
ventilators when used with its factory set functions and settings.
The inverters are microprocessor-controlled and use state-of-the-art Insulated Gate
BipoIar Transistor (IGBT) technology. This makes them reliable and versatile. A
special pulse-width modulation method with selectable Pulse frequency permits
quiet motor operation. Comprehensive protective functions provide excellent
inverter and motor protection.
