SIEMENS MICROMASTER ,MICROMASTER 420/430/440 series

MICROMASTER 420/430/440

The MICROMASTER 420s are a range of frequency inverters for controlling the speed of
three phase AC motors. The various models available range from the 120 W single phase
input to the 11 kW three phase input.

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.

The MICROMASTER 420 with its default factory settings, is ideal for a large range of
simple motor control applications. The MICROMASTER 420 can also be used for more
advanced motor control applications via its comprehensive parameter lists.
The MICROMASTER 420 can be used in both ‘stand-alone’ applications as well as being
integrated into ‘Automation Systems’.

Ambient operating conditions
Temperature
Min. operating = -10°C
Max. operating = 50°C
Humidity Range
95% Non-condensing

Altitude
If the inverter is to be installed at an altitude > 1000m, derating will be required.
(Refer to MM420 Reference Manual)

Shock
Do not drop the inverter or expose to sudden shock.

Vibration
Do not install the inverter in an area where it is likely to be exposed to constant vibration.

Electromagnetic Radiation
Do not install the inverter near sources of electromagnetic radiation.

Atmospheric Pollution
Do not install the inverter in an environment, which contains atmospheric pollutants such as dust, corrosive gases, etc.

Water
Take care to site the inverter away from potential water hazards, e.g. do not install the inverter beneath pipes that are subject to condensation. Avoid installing the inverter where excessive humidity and condensation may occur. IP54 and IP56 units offer additional protection.

Overheating
Mount the inverter vertically to ensure optimum cooling. Additional ventilation may be required for horizontal mounting.
Ensure that the inverter’s air vents are not obstructed. Allow 100 mm clearance above and below the inverter.
