7 4x-Frame Sizes Disassembly and Assembly Instructions
7.1 Electrostatic Discharge (ESD)
Frequency converters contain dangerous voltages when connected to mains voltage. No disassembly should be attempted with power applied.
Remove power to the frequency converter and wait at least 20 minutes to let the frequency converter capacitors fully discharge. Only a
competent technician should carry out service.
ELECTROSTATIC DISCHARGE (ESD)
Many electronic components within the frequency converter are sensitive to static electricity. Voltages so low that they cannot be felt, seen or heard can reduce
the life, affect performance, or completely destroy sensitive electronic components.
Use proper electrostatic discharge (ESD) procedures to prevent damage to sensitive components when servicing the frequency converter.
NB!
Frame size is used throughout this manual where ever procedures or components differ between frequency converters based upon the unit's physical size.
Refer to the tables in the Introduction Section to determine frame size definitions. See Section 8 for 5x-frame sizes disassembly and assembly instructions.
