disconnected. Therefore always wait for 5 minutes after
disconnecting the inverter from the power supply before carrying
out work on any MICROMASTER modules.
This equipment is capable of providing internal motor overload
protection in accordance with UL508C section 42. Refer to P0610
(level 3) and P0335. 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 93 of the Operating Instructions).
Class 1 60/75° copper wire only.
Refer to the Operating Instructions for tightening torques.
!Caution
Children and the general public must be prevented from accessing
or approaching the equipment!
This equipment may only be used for the purpose specified by the
manufacturer. Unauthorized modifications and the use of spare
parts and accessories that are not sold or recommended by the
manufacturer of the equipment can cause fires, electric shocks
and injuries.
Notes
Keep this Getting Started Guide within easy reach of the
equipment and make them available to all users.
Whenever measuring or testing has to be performed on live
equipment, the regulations of Safety Code VBG 4.0 must be
observed, in particular § 8 ‘Permissible Deviations when Working
on Live Parts’. Suitable electronic tools should be used.
Before carrying out any installation and commissioning
procedures, you must read all safety instructions and warnings,
including all warning labels attached to the equipment. Make sure

1 Mechanical Installation
!Warning
THIS EQUIPMENT MUST BE GROUNDED.
To ensure the safe operation of the inverter, it must be installed
and commissioned by qualified personnel in full compliance with
the warnings laid down in the MICROMASTER 420 operating
instructions.
Take particular note of the general and regional installation and
safety regulations regarding work on dangerous voltage
installations (e.g. EN 50178), as well as the relevant regulations
regarding the correct use of tools and personal protective gear.
The mains input, DC and motor terminals carry dangerous
voltages even if the inverter is inoperative, wait 5 minutes to allow
the unit to discharge after switching off before carrying out any
installation work.

!Warning
Before electrical installation, set the power supply frequency for
Europe or North America. For operation on the North American
Power Supply, set the DIP-Switch (2) to 60 Hz (up). For operation
on the European Power Supply, leave the DIP-Switch (2) in the
default position 50 Hz (down).

3 Avoiding Electro-Magnetic Interference
The inverters are designed to operate in an industrial environment where a high
level of EMI can be expected. Usually, good installation practices will ensure
safe and trouble-free operation. If you encounter problems, follow the guidelines
stated below.
Actions to Take
Ensure that all equipment in the cubicle is well grounded using short, thick
grounding cable connected to a common star point or busbar
Make sure that any control equipment connected to the inverter (such as a
PLC) is connected to the same ground or star point as the inverter via a
short, thick link
Connect the return ground from the motors, directly to the ground connection
(PE) on the associated inverter
Flat conductors are preferred as they have lower impedance at higher
frequencies
Terminate the ends of the cable neatly, ensuring that unscreened wires are
as short as possible
Separate the control cables from the power connections as much as
possible, using separate trunking, if necessary at 900right angles.
Whenever possible, use screened leads for the connections to the control
circuitry
Ensure that contactors inside the cubicle are suppressed, either with R-C
suppressors for AC contactors or 'flywheel' diodes for DC contactors fitted to
the coils. Varistor suppressors are also effective. This is important when the
contactors are controlled from the inverter relay
Use screened or armored connections for the motor connections and ground
the screen at both ends using cable clamps
!
Warning
Safety regulations must not be compromised when
installing inverters!

4 Commissioning the MICROMASTER 420 Inverter
The MM420 is supplied with a Status Display Panel (SDP). Default parameter
settings cover the following requirements:
The motor rating data, Voltage, Current and Frequency are all compatable
with the inverter data. (A standard Siemens motor is recommended).
Linear V/f motor speed, controlled by an analogue potentiometer.
Maximum speed 3000 min-1 with 50 Hz (3600 min-1 with 60 Hz),
Controllable using a potentiometer via the inverter’s analogue inputs
Ramp-up time / Ramp-down time = 10 s
If more complex application settings are required, please refer to the parameter
listing in the Operating Instructions.
For changing parameters you need one of the optional modules "Basic Operator
Panel" (BOP), "Advanced Operator Panel" (AOP) or communication options.
See Operating Instructions and Reference Manual.
In this Guide, Commissioning with SDP and "Quick Commissioning" with
the BOP (including the neccessary parameters) are explained.
For replacing the SDP by an Operator Panel see Section 6

F0011 Motor overtemperature by I²t calculation
Overcurrent (Fault F0001)
Ramp up time set too short. Increase P1120 accordingly.
Voltage boost too high. Reduce parameters P1310, P1311 and P1312 to
prevent excessive magnetization of the motor.
Overvoltage (Fault F0002)
Ramp down time set too short. Increase P1121 accordingly.
Note
It is possible that the motors’ performance may be affected at low frequencies if
parameter P1310 falls under 50 (default value).
