General

!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 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.

♦Risk of electric shock. The DC link capacitors remain charged for five minutes

after power has been removed. It is not permissible to open the

equipment until 5 minutes after the power has been removed.

♦HP ratings are based on the Siemens 1LA motors and are given for

guidance only, they do not necessarily comply with UL or NEMA HP

ratings.

!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 these operating instructions 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

Transport & Storage

!Warnings

♦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 101).

Commissioning

!Warnings

♦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 EN50178 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, DC+, DC-

♦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 2-4 on page 25, to prevent inductive and capacitive

interference from affecting the correct functioning of the inverter.

Operation

!Warnings

♦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.

♦This equipment is capable of providing internal motor overload protection in

accordance with UL508C section 42. Refer to P0610 (level 3) and P0335, I2T

is ON by default. 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 102).

♦This equipment must not be used as an ‘emergency stop mechanism’ (see

EN 60204, 9.2.5.4)

Repair

!Warnings

♦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
