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 chapters and are repeated or supplemented

at critical points throughout these chapters.

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.

WARNING

 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 suitable 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 modules. The drive unit discharges itself during this

time.

 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 230/460 V

when protected by an H or K type fuse, a circuit breaker or self-protected

combination motor controller.

 Use Class 1 60/75 °C copper wire only with the cross-sections as specified in

the Operating Instructions..

 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.

NOTES

 Before installing and commissioning, please read these safety instructions and

warnings carefully and all the warning labels attached to the equipment.

 Make sure that the warning labels are kept in a legible condition and replace

missing or damaged labels.

 Maximum permissible surrounding ambient temperature is 50°C.

3 Factory setting

The MICROMASTER 420 frequency inverter is set in the factory so that it can be

operated without any additional parameterization. To do this, the motor parameters

set in the factory (P0304, P0305, P0307, P0310), that correspond to a 4-pole 1LA7

Siemens motor, must match the rated data of the connected motor (refer to the

rating plate).

Further factory setting:

The following optional components are additionally required in order to establish

communications between STARTER and MICROMASTER 420:

 PC <-> frequency inverter connecting set

 BOP if the USS standard values (refer to Section 6.2.1 "Serial Interface

(USS)") are changed in the MICROMASTER 420 frequency inverter

NOTE

The USS parameter settings in the

MICROMASTER 420 frequency inverter and

the settings in STARTER must match!

4.2 Establishing communications between the

MICROMASTER 420 ⇔AOP

 Communications between AOP and MM420 are based on the USS protocol,

analog to STARTER and MM420.

 Contrary to the BOP, the appropriate communication parameters - both for the

MM420 as well as for AOP - should be set if the automatic interface detection

was not carried-out (refer to Table 4-1).

 Using the optional components, the AOP can be connected to the

communication interfaces (refer to Table 4-1).
