Siemens 420 manual Operation, Repair, Dismantling & Disposal

Issue 07/04 Safety Instructions

Operation

WARNING

♦Motor parameters must be accurately configured for the motor overload protection to operate correctly.

♦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 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 V / 460 V when protected by a time delay fuse (see Tables starting on page 160).

♦This equipment must not be used as an ‘emergency stop mechanism’ (see EN 60204, 9.2.5.4)

Repair

WARNING

♦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 contained in this manual.

♦Any defective parts or components must be replaced using parts contained in the relevant spare parts list.

♦Disconnect the power supply before opening the equipment for access

Dismantling & Disposal

NOTES

♦The inverter’s packaging is re-usable. Retain the packaging for future use or return it to the manufacturer.

♦Easy-to-release screw and snap connectors allow you to break the unit down into its component parts. You can then re-cycle these component parts, dispose of them in accordance with local requirements or return them to the manufacturer.
