Warnings, Cautions and Notes

The following Warnings, Cautions and Notes are provided for your safety and as

a means of preventing damage to the product or components in the machines

connected.

Specific Warnings, Cautions and Notes that apply to particular activities are

listed at the beginning of the relevant sections.

Please read the information carefully, since it is provided for your personal

safety and will also help prolong the service life of your MICROMASTER 420

inverter and the equipment you connect to it.

!Warnings

This equipment contains dangerous voltages and controls

potentially dangerous rotating mechanical parts. Non-compliance

with Warnings or failure to follow the instructions contained in this

manual can result in loss of life, severe personal injury or serious

damage to property.

Only suitably qualified personnel should work on this equipment,

and only after becoming familiar with all safety notices,

installation, operation and maintenance procedures contained in

this manual. The successful and safe operation of this equipment

is dependent upon its proper handling, installation, operation and

maintenance.

The DC link of all MICROMASTER modules remains at a

hazardous voltage level for 5 minutes after all voltages have been

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

that the warning labels are kept in a legible condition and ensure

missing or damaged labels are replaced.

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.

2 Electrical Installation

!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).

When installing the inverter after a period of storage please refer to

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

Note:

Frequency setting: The inverter is delivered as follows:

DIP switch 2:

♦Off position: European defaults (50Hz, kW etc.)

♦On position: North American defaults (60Hz, hp etc.)

4.4 Commissioning with the Basic Operator Panel

With the Basic Operator Panel, which is available as an option, the user can

change the default settings of the MM420 to meet particular application

requirements. Using the BOP it is possible to access level one, two and three

parameter sets. The BOP hosts the following features:

Speed, frequency, motor direction and current etc displayed as required

For direct control, the BOP is mounted directly onto the front panel of the

inverter

For “Quick Commissioning” of the inverter the Getting Started Guide should be

used. For other methods of commissioning, see the Operating Instructions or

Reference Manual.
