Replacement Of Boards - Siemens SIMOVERT FC Series Operating Instructions Manual

Replacement of Boards

5 Replacement of Boards
The SIMOVERT Master Drives converters are operated on high voltages.
All work on the equipment must be carried out in compliance with national electrical
standards (in Germany: VGB 4).
Maintenance and servicing work must be carried out by qualified personnel.
Only spare parts authorized by the manufacturer may be used.
Owing to the DC link capacitors, the unit remains at a dangerously high potential for at least
5 minutes after disconnection from the supply. The unit must not therefore be opened for at
least 5 minutes after supply disconnection.
Voltage may be present at the power terminals and control terminals even when the motor
is stationary.
If you need to work on the unit when it is switched on:
♦ Do not touch any live parts.
♦ Make sure that you use proper measuring instrumentation and protective clothing.
♦ Stand on a non-earthed, insulated and anti-ESD surface.
Failure to observe this warning can result in death, severe personal injury or substantial
property damage.
Before contacting your Siemens service department with an enquiry, make sure that you know the internal item
number (version) of the T100. You will find this number on the board (see Fig. 3.2).
The boards contain components which can be destroyed by electrostatic discharge. Your
own body must be discharged before you touch an electronic board. The easiest way to do
this is to touch a conductive, earthed object (such as bare metal part of cubicle)
immediately beforehand.
Replacing a T100 board in the electronics box
♦ Undo the board's fastening screws above and below the withdrawing handles (see Fig. 2.2).
♦ Use the handles to withdraw the board carefully out of the electronics box, making sure that the board does
not catch on any adjacent parts.
♦ Insert plug-in jumpers on the new replacement T100 board in the same way as on the old one (see Fig. 3.2
and Chapter 3.4) if you wish the functions to remain the same.
♦ Mount software module on the new technology board (see Chapter 2.2).
♦ Push new board carefully along guide rails into electronics box as far as it will go.
♦ Fix the new board in position by tightening the fixing screws above and below the handles.
♦ The system setting of the technology parameters must be input again for the T100 (see manual of the
software module used).
